I spoke with the deals, what needs to happen is Chrysler needs to have millions of complains and maybe a few lawsuits before they make corrections or changes. Your laws might be different than CA, but if I have to take into service for more than twice for the same thing and the Jeeps hits at the dealer for 30 days, then I can lemon law it.
I think it is cool that you are completely honest about the Jeep. Many online feel obligated to always be positive. Being fully transparent is appreciated!
Nice vid 👍🏻. We have a 2020 EcoDiesel JL as well. I’m just S of u in Idaho. This summer I noticed the temp of the coolant creeping up high. I didn’t have the engine decrease power, but I didn’t like the temp increase. An old trick my dad taught me worked: make sure the a/c is off and crank your heater to full hot, full fan with all vents open. Keep the Windows down, unless u like hanging out in an oven😁. In about 2 minutes , my coolant temp dropped about 10°F. It’s not the best feeling in the cab when it’s 100°F outside😆, but with the windows down, it’s tolerable (and just temporary). I only used the trick while climbing over a mountain pass. It May be enough to let You keep up with the group, keeping the engine at full power, and keep the coolant temp down 👊🏻. Using your heater core this way is like adding another radiator to expel extra heat while working the engine.
I tow a 5500lb camper behind my Gladiator Eco-Diesel sport lifted 3.5” and 37’s. Over the summer I was towing up a small grade in about 92/93 degree weather and all of a sudden I lost power for a couple mins. It genuinely scared me as I had zero idea what was wrong, but I got over the hill and started down and power came back. I never figured out why and it never happened again so I had forgotten about it until you mentioned it in a previous video. So now I know what to look for. Thanks for this video! P.S. I’ve got just under 10k miles on mine and I’m about to go put my 4th Def fluid jug in. It tows WAY better than I would have expected with my setup but it just guzzles def fluid while doing it.
I’m only going to chime in on this for the readers that might be trying to decide if they want a EcoDiesel or the 3.6L. I have to I find Casey’s conclusion contradictory. If you intended on adventuring with your Jeep and want peace of mind, your way better off with the 3.6L. I run 35” M/T’s and have a 2 1/2” lift on my JTR and it’s a dream to drive on the highway. There is literally zero fuel economy benefit from the the EcoDiesel given the premium of the cost of the motor. The DEF fluid issues guys are having is a hassle I definitely don’t want when I’m in the middle of nowhere on a camping trip! And the last observation I’ve made about the Diesel is the added front end weight of the vehicle, if you like to play in the snow in the winter they tend to submarine from what I’ve seen. From listening to all the issues you guys are having with the Diesels the only benefit I actually have heard is that it has great passing power with bigger tires one your way to the auto parts store to pick up more DEF fluid….just my two cent. If you want a hassle free experience and want to save a nice chunk of change, get the 3.6L
Range is a huge benefit with the diesel . I have 40” tires and heavy oneton axles on my 21 JLURD . My Jk was getting 1/3 the range with the same mods .
For my benefit only, the ecodiesel meets my company requirements of 27 mpg on the hwy. For that reason alone I opted for the ecodiesel. I get $900 per month for vehicle allowance meeting that requirement.
I spend almost half of what Shaun does on fuel when highway driving to our destinations. Mind you in Canada, diesel is almost always cheaper at the pump as well. Just this weekend, we topped off, drove for about 4 hours, and topped off. Mine was $40, and Shauns 3.6L was $72. Im saving a ton on fuel on the highway.
@@Casey250 Diesel in the north is the same cost, your getting a touch better fuel econ. Most guys here have such terrible issues in -35/40c they exaust delete in the first year after it wont start all winter. Premium engine with premium costs.
@@Casey250 I agree with you on fuel savings. On our trip from SF Bay Area to Colorado and back, we all added up our fuel costs. We traveled as a group and always filled up at the same stations. The other rigs in my group spent $950+ on gas. My total was shy of $450 in diesel. Plus $20 to top off my DEF. huge savings.
Coming from a truck driver, with diesel motors TQ doesn’t get you up the hill HP does, TQ just gets you going. So that explains why the 3.6 is passing you up hills. Also def and diesels don’t like cold temperatures, make sure if it’s going to be in the low teens (inFahrenheit) or single digits to use anti gel so the diesel doesn’t gel up. If your idling or going at low speeds you will have more def use than if your going down the highway.
The DEF tank has a sender just like a fuel tank. If you are rock climbing it thinks it's running low due to the steep angle. For the long haul up highway hills, it's best to manually pull the auto back a gear so the rev counter is around 3,000 rpm. The diesel will otherwise hold onto a gear without downshifting, placing more load on the engine and potential overheating, especially with taller tyres! Thanks
I drive a Semi truck. On my truck I have an auxiliary switch that allows me to manually turn on the engine fan if I need to cool down the engine in the event of overheating conditions. It should be possible to do this on the jeep too. I love your videos Casey and I've watched you for while now. I'm also a fan of The Story Till Now. Thank you for sharing.
I have 9k miles on mine bone stock so far and zero issues.... I've been in 112 degree heat this summer in 4 lo and pulling grades out of tahoe which is very steep. Not even a degree change in that heat.... no def issues at all. Seems to burn about average from my experience with def fluid in other vehicles. Absolutely love it! Hope it doesn't have the problems you have had.. oh I have a banks tuner, which is the only upgrade so far since all parts are on back order.
It’s the mods that ruin the vehicle and make it where it won’t cool properly. Ask the car engineers, they will tell you that the vehicle was engineer to work best stock. Any mods the average Joe has little knowledge on how that is going to effect cooling, etc.
Please keep showing your Wrangler/Rubicon ecodiesel in your videos, the good and the bad. I’m the only guy for a couple hundred miles that has a ecodiesel Wrangler Willy’s edition 3.0L Turbo. You’re such a great source. You’ve helped me learn about my Jeep make decisions on what I’m doing/going to do with mine. I really appreciate you sharing your experiences and knowledge with all of out here on UA-cam.
I haven’t seen the limp mode issue while climbing a steep grade and I have climbed up steep grades in 100 deg (f) weather while full loaded out. Although, when my 2021 eco diesel JLUR had about 2k miles, it did go into limp mode randomly on the highway on a trip to Colorado (relatively flat section); maybe 4 different times in one day. During that nights camp, I disconnected the battery for about half hour, then hooked it back up. Shortly after that, the uConnect stereo prompted me to do a firmware upgrade (not sure if that was part of the fix) and 1k miles later I’ve had no issues. As far as DEF, I’m consuming 2.5 gallons every 2k miles-ish. No where near what I expected to go thru. But so far, I love my eco diesel. Lots of power and great fuel mileage compared to what I was getting in my 2015 JKUR (13mpg vs 22mpg).
I'm in Colorado Springs and ordered a JLU Eco diesel. Should be here end of October. Went with the JLU Sport Altitude because I like to build stuff out. Glad to hear it does well in the mountains here. I have a 2017 JKU manual 6 speed that I will miss, but i really wanted the diesel. I hit you with a sub just encase i need to pick your brain after my new Jeep gets here.
@@chickenpermission9969 the 8 speed is great. I don’t miss manuals at all. Literally my first auto vehicle I’ve bought since been driving 16 years. Torque converters multiply and preload driveline without damage.
@@chickenpermission9969 Sorry I meant a JLU. You were able to order a 2021 JLU eco diesel? I'm waiting to order a 2022 JLU eco diesel but as far as I know they aren't taking orders yet.
Few things I'd like to point out to people debating on getting an ecodiesel in general. Having owned a 17 ram. Under 25,000 miles my exhaust and all emissions components (fell off). It ran extremely clean. The tune i had In it produced almost zero soot no matter how much load you gave it. The EPA killed almost all options to do this in today's time 2021. Now knowing the constant issues this engine has been plagued with. EGR failures causing engine fires. Chrysler issiuing recalls on factory tune causing a new flash to be installed basically killing any power the engine may have made before. Severe turbo lag from new recall. Throwing connecting rods thru the block for no reason. Crank position sensor failure. No big deal rite? Wrong. Step 1 pull transmission. They glue the magnets onto a plastic tone ring which is behind the flywheel. And yes they do fail more then it should. It happened to me. Had to pull transmission to change part. Sensors 500 bucks us and tone ring is 100 or so. Plus labor. Cp4 failures from low sulfur fuel ( has low lubricity ). Don't put def in the fuel system. You will need to change everything from it tank pump to the last injector in the engine. Can range over 10k in labor and parts. And warranty won't cover it. It's a user error. Modern diesels aren't worth it to me unless heavy hauling and have a warranty.
Full belly skids are a MUST for the diesels. The stock rubicon “skid plates” don’t cover the exhaust components at all. I haven’t had the DEF reporting issue, you and I got our JLRUDs around the same time. But like you, I am using more DEF than I expected, about 2x more than I expected. Haven’t been in the altitudes you’ve been, but never had an engine heat issue and I book over long hauls 75 mph, easy from NY to PA or NY to ME (similar build, 37s, full beadlocks, steel bumpers, fully belly pan, rhino-rack backbone and pioneer platform). When crawling through rock gardens, I get a high steering fluid temp warning every time. I use my Tazer JL Mini to turn on cool-down mode to gulp air into the engine bay and that fixes it. My biggest PITA isn’t a diesel issue, my JLRUD keeps throwing traction control/ACC errors. I think I have a bad wheel speed sensor. I need to take it in. I know the JKs were notorious for this problem.
You should look into the apex performance power steering cooler. I had the power steering warning crawling with stock tires, installed the cooler and have no issues with my 37s.
@@tomsimard9432 thanks! are you running a diesel JL? Want to make sure it works with them first. Northridge4x4’s site shows it as not fitting, but sometimes that’s just because they haven’t update the site. Will probably have to find a new location for the manifold, itself. Not sure if that will fit with my aftermarket bumper and winch.
@@jeckart3d I have a warn zeon winch with the factory steel bumper. It is a tight fit and you have to play Tetris to get the lines to align. It also requires drilling a couple holes in the frame. It is like anything else on a jeep, your combination of parts may have different results. I think the biggest improvement is the additional fluid and surface area because I wouldn't anticipate much airflow.
@@tomsimard9432 very helpful, Tom. Thanks! I have a warn winch, too but aftermarket steel bumper. Along with fitment, I also know the diesels have a bunch of systematic differences to their gas and electric counterparts. As long as this system is compatible-I can figure out the fitment. Thanks again!
I've got the eco diesel in a 2016 Grand Cherokee. I've had it back to the dealer 3 times now for EGR recall issues. Once, they kept my Jeep for a week in order to get parts from a dealer in Michigan. Plus, I went through the EPA issue where the fuel economy and performance actually decreased after the reprogramming. I haven't had the Def issue on hot days while climbing grades on the highway. And yes, the oil change is crazy expensive. My wife keeps complaining that the higher diesel cost and oil change cost negates the fuel efficiency gains. I also have a 2019 Rubicon 2dr with the 3.6L and manual transmission. While the fuel efficiency sucks on the Rubicon, it's still a blast to drive and the oil change costs are 1/3 of the diesel. I'm happy with the 3.6L in the Rubicon and glad I didn't opt for the diesel.
Outstanding review. We purchased an eco diesel about 3 months ago and have right at 5K miles on it. I’m been paying close attention to your videos outlining issues. I hope Jeep can address these and adopt a fix. So far though, we’ve been absolutely loving the eco diesel.
He bought the first year which is a major no-no imho. 1st year owners are essential testers. They really shouldn’t have killed the EcoDiesel. The new full-float axle could’ve made this a towing/highway road trip monster. On Gladiator even more-so…
Great Info. Just got our 2021 EcoDiesel Gladiator Rubicon a month ago. With only 800 miles on it, we set off on a two week vacation pulling a 19’ Aluminum Boat. Pulled a couple passes and was in the desert heat (85-95 degrees) all of the trip. Knocking on wood, had no problems at all. Didn’t have any idea on the cost of oil changes, glad we are a part of the dealer program and the 1st 5 of them are included. I subscribed and will keep following your updates and post if we run into any issues.
I was thinking of buying a 2015 Jeep Cherokee from Carmax in the lower 48 with only 33,000 miles on it (about 53000 km). The car has an open recall for the high pressure fuel pump which Jeep currently has no fix for. Spent about 20 minutes talking to the service adviser at my local Jeep dealer as this too, is an eco diesel. What that means is these diesels are fitted with an EGR (exhaust gas recirculation) system which, as the name implies, recirculates exhaust (soot). Over time this clogs the EGR system and the engine (like one would expect). And causes fuel system failures and all the rest detailed in your video. The diesel exhaust fluid is added nearer the tailpipe in the exhaust and what ever gases are left are burned by a spark plug there. Turning the soot into ash which eventually still blocks off the exhaust system and if left uncorrected, will destroy the diesel engine, eventually. One need only recall that older diesels in tractor trailers and farm equipment lasted for several millions of miles instead of a 100-150,000 miles before needing major "repairs". In the states the Supreme Court has just ruled that the EPA does not have the authority to make or enforce law. So, bearing in mind this is a $6-8K problem to "fix" many, including myself, have opted for an EGR delete where the soot is not recirculated back into the engine and goes still to the diesel particulate filter (think CAT). Some folks are just doing straight pipes. And the local DMV in my state has decided to give emissions exemptions to ALL diesels based on the Supreme Court ruling (beginning November 1, 2022) and the fact that the expense of near zero emission for diesel is exorbitant and ultimately, doesn't "fix" the problem. It is an untenable system. It does not work. The emissions laws in the EU are much more realistic and that is why diesels remain popular in Europe. For now in North America we are stuck with a dominant political party in California that doesn't care or understand the basic chemical laws of carbon emissions and somehow has managed to dictate their psychotic view of reality to the whole of North America. A brief look at recent emissions/ green history bears this charge out. In about 2000 there was low sulpher diesel at about 115 ppm. Then in 2010 came ultra low sulpher diesel at 15 ppm. In 2015 or so we saw the first signs that the new stricter standards were not working when VW corporation was exposed commiting fraud with the EPA (since 2009) rather than try to force diesels to be ultraclean with EGRs, DEF, DPFs, burn offs of soot and all the rest. They were fined heavily and withdrew diesels from North America entirely. Why? Because the two of the three biggest things about diesels that people love about diesels have been taken away by these ludicrous laws. Reliability and longevity. You still have torque, occasionally if the thing is running correctly. Which is only when they are very new and not choking on their own soot. At this point there is only one solution. Get rid of non-elected organizations mandating unrealistic "solutions" to created "problems" by understanding most of us have to balance the need for clean air with realistic monetary expenditures out here in the real world. Vote those bums out and vote your self in by running for office. Clean at "any cost" only works for elites like Elon Musk and the IT crowd. About 60% of the population of the United States lives on around $40 K US for a family of four. They're having trouble paying for basics let alone an $8,000 annual "repair" on their tractor, semi or ford F350. So, faced with that reality people are moving from places like California and Washington to states where it is no longer illegal to modify their diesels back to something around 2010, That's the fiscal reality that VW realized. And so are we down here in North Carolina. It is time to say "no".
Hey Casey, great channel. Just wanted to share with you I had the same issue here in europe with my diesel 2018 jeep jlu regarding the def warnings. The issue was with the def tank and its sensors not working. Took 9 month to get a replacment tank from Italy but once changed i have no more def issues.
Thanks for another information video on the diesel! I am currently at 10k miles, or 16,100 km, and I have not had many of the issues that you have, likely due to being at a lot lower altitude in the Appalachians. I keep a small container of def fluid in my Jeep, for peace of mind, when I am in remote locations. This is not only due the issues I have seen with def system but in case I were to puncture the def tank. I could repair with patch or steel putty, then put some def in to hold me over. I plan on putting a skid under it soon. When available, I may buy the 392 hood with hydro-guide to get enough airflow to avoid overheating. I haven't decided between that or trying to fabricate my own snorkel, since no one seems to want to make one for diesel.
I have the Eco diesel also. I appreciate your videos on the subject. I'm not 100% with it yet for the reasons you bring to light. Please keep up the good work.
10k miles and happy with my eco diesel. Most of my off-road adventures are in western Colorado at altitude. I've got a lift, 35s, and some other common modifications. No roof top tent and other extra stuff bolted to my rig. Mine is not a daily driver and will probably delete emissions after the warranty expires. Nothings perfect but I do feel the diesel hits the sweet spot for me.
I want to do the delete on my 2020. It is out of warranty. I filled up the DEF 3 weeks ago and could not put anymore in and the gauge told me I was 3/4 full... No warranty .
Thanks for the update on your end. I have just over 4100 miles on my 21 JLURD and the engine has been a true pleasure to drive through the Colorado mountains. I plan on adding 37" Mickey Thompson Baja Boss A/Ts (once they arrive) to accompany the Metalcloak 3.5" lift. The MC lift handles the engine weight far better than the stock springs, which I feel like were far too soft. One issue I did have while off-roading near Ouray, CO was running the AC while on the trails in 4 Low. It caused the power steering to throw an error of decreased performance due to heat issues several times. Mind you, this was stock, except for the Falcon 2.1 steering stabilizer on soft.
I have no issues. My friend in New Mexico has Jeep Wrangler Rubicon Diesel. She is always operating at an altitude of 8000 ft. Near the Sandia Mountains, she had cooling issue 2 times this summer. She was going thru a REGEN phase. I suggested to her to purchase the Mojave/ or the 392 hood. This will help with moving a lot more heat from underneath the hood. Also suggested cutting out some of the plastic that are in the fenders. Easier for the hot air to escape. At the end of the Day she went with the Mojave hood. Had it painted to jeep color and it actually looks sharp. tough looking and better looking. and ZERO ISSUES with limp mode or temperature rising.
As I understand it it’s hard to put in oil cooler in there as there is barely any extra room. And people say you don’t want to block more airflow. Thoughts?
I have a 21' ecodiesel gladiator and love it. Plan to leave it mostly stock and hopefully I don't have any of the problems the early one's had. It's been almost 2 years since the gen 3 came out in the Ram. Think they have revised them a bit.
I noticed with mine that low speeds and towing/offroading will consume more def. I have the ecodiesel but i use eco fuel saving tabs. They improve combustion, give more mpgs, reduce emissions, and less regens. I also run Amsoil motor oil, engine coolant and transmission fluid..... engine operating temps are down with the Coolant and transmissiom fluid. Also get a scan guage or scan tool. It can see temps of turbo, dpf, and soot load.
My diesel is supposed to arrive this week and I’m pretty excited. And yes, load on the engine effects DEF is consumed at a higher rate. I’d put it in the same category as gas. Always bring extra, never be unprepared. But once I get mine I’ll be starting my own channel and will be doing intervals reviews on the truck. And as someone who grew up around 1 ton diesels, oil changes have never been cheap. But damn son are they fun to drive! Happy trails, Casey!
First thank you Casey for your content-the worst thing about horror stories is when numerous people are telling them and you're not the only one that has these issues yet your content with so many others helped me decide to not get the ecodiesel, I settled with the 4cyl 2.0t and was somewhat hesitant but it's gives the right amount of torque and no gremlins thus far.
The diesel has more drawbacks then advantages. The 3.6l has gotten jeeps everywhere the driver tries to take it. You’re real money will start to come when the warranty is up. To each his own though! I enjoy seeing your build process and your journey with the eco diesel!
I love the idea of a diesel but not a modern one with all the sensors....irregardless of how hard I off road I have experience to many issues with my colorado diesel 2.8 duramax and it just wasn't worth it. The wait alone (mind you pre cv19) was 3 weeks no thank you. Then you have limp mode when these issues happens.
I've done a bunch of different off-roading like you have, but I drive a Colorado ZR2 diesel. I've been from sea level to 13,000 ft. I have 60,000 miles on mine now and literally haven't had a single issue with it. That sucks that the eco diesel is so plagued with issues. I can get an oil filter for mine for $14 US.
I got a gas gladiator for one simple reason. Simple proven engine that’s naturally aspirated, makes more power (not torque), and weights less. Less weight means less stress on the vehicle and easier to make it over obstacles. The power is negligible, but it at least gives it the same capability albeit at higher rpm (not a big deal since rpm doesn’t = piston speed or inertia, a lower rpm longer stroke engine can have a higher piston speed or more inertia than a higher rpm shorter stroke engine). Lastly, the pSTAR is a proven engine with excellent durability. It’s simple and doesn’t have many points of failure.
Very interesting comment and one that I agree with. That said this diesel is is a lot of engine for this application and quite literally fills the engine bay. It's a good option for those needing or wanting the extra torque but utilizing it is a problem. Diesels generate more heat from higher compression. Adding lifts, larger wheels with more negative offsets, larger and heavier tires, heavy aftermarket bumpers and roof racks, winches, lights, and hauling around a lot of gear all puts extra strain on both engines and every part of the suspension and drivetrain. And the diesel itself adds several hundred pounds to a vehicle with that option. Re-gearing is appropriate for either engine but getting rid of the extra heat is one important issue. As I recall Jeep engineers widened the front grill slots on the Gladiator to aid cooling for the original 3.6L V6 engine before the diesel option was even available. Maybe the grill will be widened even more along with the addition of various coolers (if they will fit)? I'm mindful that Jeep spends millions and millions on testing and engineering to achieve a balanced drivetrain with reliability. Meeting emissions' mandates hampers that goal and vastly complicates the entire system. While I recognize this overheating issue happens on some stock diesel vehicles changing one crucial component like tire size affects many other components as well as performance. Unsprung weight for instance has a geometric impact on performance and an increase in diameter effectively lowers the numerical gear ratio taking either engine out of it's intended power band. I'm sure Casey knows all this and a lot more but is pushing his vehicle for his channel and willing to put up with the compromises. Perhaps the average Wrangler or Gladiator owner would be well served stock or maybe modestly increasing tire size. But we all know that's not going to happen as aftermarket companies are willing to sell product that compromises the original integrity of the vehicle.
@@dantimber my 3.6 Rubi grill has plastic filler so it’s not fully opened up. . Torque is great. I had a 12v twin turbo Cummins ram. But for my application it only increases range not capacity and reduces performance with the added weight. . If the diesel had a 9k tow rating and 2k payload, then I’d say it’s worth it for the added capacities. For me and my needs the gasser just works better. No turbo lag, deep gearing, and a power train that is easy to maintain and be reliable.
@@KTMcaptain That makes sense. I'm only speculating but Jeep could probably make a number of small changes to increase the towing and load capacity of the diesel engine in the Gladiator like modifying the grill for more air flow and coolers. But that might necessitate frame and suspension components as well as things like the driveshaft and brakes. One change can trigger a bunch of other changes. But as it stands now I agree with you that the gas engine has advantages that may outweigh the diesel. I'm sure Jeep is well aware of the situation.
I've been using Amsoil Signature diesel oil with great lab analyses from Blackstone. I also order the Wix USA made oil filter for my 2016 Ram, 2nd gen diesel. I change at 10,000 miles. I now have 128K after putting it into service at 700 miles.
A lot of my jeep friends were super excited that jeep was FINALLY going to provide a stock diesel option. Only problem, jeep did it WAY too late. If they would have done it in 07 or earlier, it would have been awesome. Unfortunately, with a diesel these days, the EPA has mandated a slew of changes since 08 that chokes the engine and inevitably causes the buyer money out of their pocket. I have a 2015 ford 6.7l diesel. The problem of having to fill the DEF is the least of worries, quite frankly. Not only does it have the filter that requires hard running for long times to clean, If you don't run the vehicle like that, you'll end up having to replace the filter which is 4-6k. Fast forward to last year when I saw my first jeep diesel vid. Not only did they add that silly front axle separator to save a few MPG, there is a ton of wiring and sensors that are just waiting to get ruined or dirty on the trail and fail. Not to mention the actual DPF and DEF tank to break, hit, and ruin. After seeing that and the lackluster HP/TQ that the diesel provides, I would say get a gasser and install a super charger or get the hemi. Diesels, unless you're hauling horses or campers, are pretty much a pass these days.
AZ to Vegas and back with my stock diesel during the last heat wave we had, no temp issues. Kept an eye on them after watching your last video. I do sometimes have a rack and roof top tent that adds a ton of drag and plan on pulling a small camping trailer, so I am a bit concerned. Loved the torque in the hills, so much better than my 2015 Rubicon on the highway and trails. Would by another diesel in a heart beat.
I save a bunch of money on DEF just getting it from the pumps at truck stops. Usually works out to $2.79 @ gallon USD. Also not dealing with spilling DEF etc.
I have owned an Ecodiesel Ram 1500 since 2015. It has the same exact engine as your Jeep and the same exact issues with the EGR. Let me give you a friendly advice (GET RID OF IT as soon as you can!!!) 1. Those EGRs have a tendency to melt and as a result, engine catches fire. The replacement is super expensive (around 5k US). 2. The oil cooler, over time cracks and lets oil sip into the cooling system.(bad design). It took me about 20 flashes of the overall system to clean it. If this happens, depending on the severity, you might not be able to clean the cooling system well enough to continue using the engine. 3. The RAM had decent sound proofing to make the engine sound OK (it gets louder over time). Your Jeep probably already sounds super loud with that diesel and it WILL get worse over time. Cheers and happy wheeling. BTW, I have owned a number of wranglers as well, not the diesel ones of course, but the vehicle is no stranger to me.
Experienced the same issue of power and speed reduction due to increased engine temperature.. Outside air temperature was 90 F while driving I-80 eastbound in Nevada. Climbing a long uphill grade at highway speed (70 MPH) the vehicle suddenly reduced power and limited speed.
Really informative and helpful, great work Casey. Good tip on the Pennzoil 5W-40, we'll be stocking up since our Jeep Wave credits are running out soon 🤙🤙
I do my own oil change on my 2016 Jeep Grand Cherokee Eco diesel. I order everything on Amazon and then use an oil VAC-Pump setup. Supply's= Rotella T6 $35 per x2 and 6 oil filter for $34........ all done for less than $100 US Dollars and with the VAC system is a bit pricy, but I've never had to go underneath and pull the oil plug. Super easy stuff.
Casey, I own a 2021 JKURD. Its equipped with an aev 2.5, aev beadlocks, and 37" nitto ridge grapplers. I do feel like the EcoDiesel is ok with the stock 3.73, but I feel like it lugs in 8th gear, and has a little less to be desired. I was planning on 4.10 gears, but 2K for such a small difference isnt a good investment. The gear calculator shows that a 4.2 ratio will being it back to stock, but with the added rolling mass and heavier items, I believe a 4.56 will be ideal. I wish there was a 4.30 option but nobody makes a 4.30 for the JL 210mm front axle. What has kept you from regearing and if you did regear, what is the ratio you will likely run?
The Epic Adventure Outfitters blue gladiator has 4.56 gears and yes it will hold 8th gear a little better, I don't find it to be a problem. Fuel economy on the trips we have been on is near identical. So for the money to regear, its low on my list of things to buy.
I have a '21 JLUR ED. I tow a 1,500 lb. teardrop camper and overheated climbing from 9,000 to 11,000 ft. on stock wheels/ tires in July on Colorado. I tried all sorts of things to get to the top, but slamming it to the floor and only being able to go 40 mph was ridiculous. Frustrating for sure. Thanks for the oil recommendation! I only have 1 freebie oil change left on the Jeep Wave program. lol
Try tuning it lol. You can get tunes for these. I use fuel saving tablets. They improve combustion, performance, made engine quiter, and have less regens.
I've towed up to 7,000 lbs so far with my EcoDiesel no heat issues it didn't even move any pressures or temps during summer but max elevation was 4,000 ft on that trip and no heavy grades. Also 16.8 to 17.7 MPG
i would run a separate transmission cooler and separate the transmission cooler from the radiator to help with engine temps. those tires are guarantee raising the temp significantly.
I have and haul with my Libby crd. Maybe this might help I had issues with Mtn climbing 3 things: 1 - egr to manifold pipe had a crack. 2 - 4 glo plugs bad with 3 rockers replace. 3 - air flow sensor harness bad. 98% fixed and no more over heating. Now I can pass semis and drive in Tx heat, haha with ac on too. ~Christine
I can attest to the def levels. I went off road with just under half a tank, did about 25 miles up and down a mountain, almost ran completely out. Don’t know how the first half lasted three thousand miles.
I've only had one "high heat" issue, we were on the trail for about 3hrs and popped out on to a road that was 50mph, but steeply uphill. It bogged bad and just wouldn't go. The day was 109F at 6500ft elevation. I added Redline Water Wetter, never had it happen again since and we have really high passes (9,000+ft) and a heavily loaded JT-R on 37s, stock gearing, heavy beadlocks, and a 6" lift. Redline Water Wetter.... If you live somewhere hot or climb high passes, add two bottles your coolant, you'll thank me later. The 3.6L guys can definitely run it as well, just go one bottle in your radiator or overflow. If you live in cold temps, water cools better than coolant, so keep it as weak as possible, your comfort level will vary, but Redline + water + a bit of coolant will treat you right. EcoDiesel powered Jeep....literally nothing better on the trail, so low drama. I live an hour form the Rubicon and I'm up there frequently along with our other incredible trails in NorCal, and they are serious rock crawling. Wouldn't trade it for the world, even a 392.
I've been driving trucks since the 1970s and still to this day. Way back before computers got bolted on to trucks, we had mechanical fuel injection. Meaning, you could actually adjust each injector with a wrench to give your engine more power. This was on a 1976 Mack truck I nicknamed "Flykiller" because of all the black smoke that poured out of the exhaust stack - not to mention all the 10W40 oil it burned. Oh yeah, and no EGR hoses or anything. Any crankcase smoke was vented directly below the engine from the blowby pipe. Polluting yes, but reliable beyond your wildest dreams. Many years later came came DPF filters. First generation DPFs were terrible. They were forever clogging up going from Stage 1 - 2 - 3 - and finally limp mode Stage 4. At this point, your only recourse is to bring the vehicle back to the dealership were they have a special machine to unclog what looks like a coffee can which a bunch of straws inside. I'm not so sure how long your going to keep your Eco-Diesel after the warranty runs out, but it's going to cost you an arm and a leg to keep that thing mobile. Diesel engines are terrific - it's just all the extra, modern junk around it that's the problem.
Good info. I will say I pulled my boat (2500lbs) 360ish miles one way across the state of Virginia from the mountains to the Chesapeake Bay there’s two fairly large mountains with long hauls. I was using a 2021 stock jeep wrangler Sahara with the eco diesel and I didn’t have any over heating problems so far but I’ll keep a Close eye on it. This trip is a fairly common trip I do throughout the summer and fall.
Hello, I'm Ralf from Germany. I have a 3.0 eco diesel Gladiator. Weight 2.9t empty and I'm towing a 3t caravan. I also had temperature problems. Now from an oil temperature of 100 C°, the water is additionally heated via the water oil cooler. I therefore installed an additional oil cooler air/oil cooler. No matter which mountain I can no longer get above 105 C° water/oil temperature. Material costs in Germany approx. 1200 €.
Casey, thanks for the up date. I purchased a 2021 JWURD and have about 2000 miles on it. I haven't done much off roading yet. Im still getting it ready to go out there. Im going to lead the running gear stock to get a feeling for what it can do before I start upgrading wheels and tires. I want to compare the handling as I make upgrades. I watch most if not all your videos. Keep up the good work.
Good information in your video. Thanks. I’ve had a Wrangler with the 3.8l for 12 years and 182k. My only complaint is the lack of power. I’m planning to get a Gladiator within the next year and really hoping the eco diesel was the right engine choice for me. Glad to hear you would buy it again.
Just a heads up. Most of the harnesses connections in the ecodiesels are the weak point. The techs aren't trained how to diagnose them so they throw parts at it. I've had to disconnect, reconnect, and wire tie most connectors in the main harness on my Ram. Cleaning soot from your MAP sensor is a maintenance item unless you tune it. I use GreenDiesel tuning in my Ram.
I wonder how Jeep tuned the EcoDiesel engines? This generation of EcoDiesel has been pretty rock solid in other countries, as well as with the RAM trucks. That covers quite a lot of brands that use the VM Motori EcoDiesel. Either Jeep has tuned it in some funky manner, or it's a combination of how Jeep uses the drivetrain. With the amount of torque that it has, it really shouldn't be overheating when driving on a paved incline road. Something isn't right.
I was excited when I heard they were putting the diesel in the Gladiator because I wanted to do an Overland build but still tow a 5000lb camping trailer to use as a base of operations. Your pros are compelling, but not enough to outweigh the cons that can leave you stranded on the trail or overheated at the side of the road. My Power Wagon with the 6.4L on 37’s loves the gas and only averages 12 mpg but it hauls everything I want and is never lacking in power. I think a Gladiator Rubicon with the 392 is the only thing that is going to get me out of the PW.
Casey, I saw the original video when you had the over-heat issue. It appears that Jeep has undercooled their diesels for high workload environments. Maybe it is time for an external oil cooler, power steering cooler, and/other aux cooling ? Or maybe it is just as simple as a change of the engine thermostat to a lower value for summer or hi-temp environs ? GL and please keep Casey-250 nation updated.
I know a few people working on an oil cooler. That i feel would make the biggest difference. The ecodiesel in the jeeps is the same as the ram, but detuned for less power because of cooling issues.
@@Casey250 It's just that the Jeep does not have the engine room or grille needed to support the ED. Jeep should have put a different grille in it with a larger front fascia. The Ram has no overheating issues. I know that the 2024 Jeep has a new grille with more airflow. Maybe replace yours with it?
1st, thank you Casey for this super informative video. Curious, do you use any after market monitoring like Banks datamonster or Edge cts2? To keep an eye on regeneration cycles, miles between regens, watching exhaust temps/idling down for safe shut down etc? I'd be very interested in your feedback on that as I've often wondered how the ecodiesel handles regens when the Jeep is used at slow speeds over great distances off road. I'm waiting for the release of the 2022 model year to place an order for my wife. We will also use it at times to travel long distances from South Carolina to CO, UT, AZ etc. Towing our Patriot Camper X3 (gross 3,500lbs). Strictly overlanding stuff, no rock crawling. Even though I'm a diesel guy, I've even looked at the 4xe as an option to avoid all the EPA mandated crap and the issues potential that comes with it. Thanks for your time
Depending on how you were loaded down, the the cooling issue could be that you were driving so fast up those grades. The auto industry sizes the radiator and fan based on going 45 mph up a 13 mile long, ~6% continuous grade in Arizona at 38°C, fully loaded to GCW with a trailer. So if you were carrying a lot and trying to push ~80mph up a steeper grade you probably were de-rated. If you don't have the heavy duty fan from the tow package it's not a surprise at all. Also, 118°C is a de-rated temperature for most vehicles because that's the point where the coolant starts to break down. Also, the DEF level issue could be from driving at an extreme angle for a really long time, or if you parked and idled on an angle for a long time. They put some heavy filtering on the level signal from the DEF tanks and it doesn't update quickly like a fuel tank does.
I have a 2019 diesel 2.2 multijet and in that 5 years of extreme wheeling I had NO issues with the DPF / AdBlue system and wiring etc. My car runs almost the identical system as the 3 liter Eco. PS, in Australia we can fill up with AdBlue at the Gas station from a bouser.
Very cool video. Just bought a 2020 EcoDiesel Unlimited Wrangler. Love it. I'm strictly on road so far and found the same regarding the DEF levels. All over the map.
I have a 2020 Gladiator and thought I would get a new one with a diesel but after watching this I’m going to keep what I have , thank you for sharing this 👍
the "derating" and overheating you mention is due to the emissions systems you mentioned earlier in the video. You simply cant have a healthy functioning diesel with emissions attached. Modern emission requirements are too tight for any diesel system and is the major flaw of EGT temps and intake pressures. In order to truly open up the eco diesel it needs a DPF, EGR delete with exhaust and intake mods followed up by a tune.
My Multijet 2.2 JL Rubiconwith 37s it runs cool on the trail even when we get 40 deg C days. I also tow a 2.5 tonne van on 2 hours drives when camping and I have no issues
Mine has overheated and shut off numerous times. First while using cetane booster, second when towing my 6000# camper. Turns out it was overheating meaning over 1500 degree egt temps. I have since getting the banks iDash and derringer and now I can watch my EGTs and I can tow my camper at 65mph without overheating.
I haven’t seen either of these issues with my JT and im on stock gearing with 39” tires. Jeep gets 23 mpg and I use a little less than 2 tanks of DEF per 10,000 miles
My Wrangler diesel has alot of the same issues his does. From what I’ve seen online, it’s about 50% of the first adopted ones. My 35 nittos and a 2.5 lift no armor or rack rubicon nets me about 18.3 combined and 3000 miles per 5 gals def.
@@mattbrew11 I have come to think part of the problem is the turbo doesn’t always kick in. Some times when I’m accelerating I get like 3mph and others I get like 10. It’s wildly inconsistent. Also, randomly, the thing will like flat out act like it’s in limp mode when accelerating with a massive delay and no power even foot to the floor and then all of a sudden out of no where kick in and have power enough toe spin 35 MTs. Almost like the computer didn’t know what to do with the throttle valve. So far, I’ve had the system fleshed. Tried removing my tazer mini, updated the tazer mini, and just recently they issued a service order for a system update to “fix a performance issue” I have noticed a slight improvement in consistency after that and haven’t had the acceleration delay after that. On a side note too, I’ve noticed my best MPG is at 45 mph. I can easily get around 27-32 mpg depending on incline when doing that. Which is weird to me since 65 nets me around 20 mpg. I’ve also had the overheating issue mentioned in the video. Happens to me when going up long steep inclines like mountain passes.
I have the 21 JT Rubicon eco diesel with about 4,000 mikes. Labor Day weekend, I did have the engine get warm as well crawling in the passes of Colorado in the Ouray/Silverton areas. The power steering light came on. We pulled over one time knowing that we still had plenty of trail ahead at low speed. I parked into the wind and opened the hood in 60 degree weather. It cooled down in about 10-15 minutes. Second time a day or two later, we had open trails ahead and picked up the pace and the light went away. Still in love with it, but definitely looking to reduce the heat under the hood.
Casey - what are your thoughts on the 2021 and newer change in grill (they have the larger holes). Is it because they wanted to use the same design used in the JT so they could add a camera or that the diesel needed more air flow? Long time follower as I also own a 2020 and just wanted to see if you had a comment. Thanks
I have a 2014 ecodiesel summit wk2, I did put a gde tune in it when they destroyed it with the emissions mod, but I love this vehicle. It's a beast. I can tow almost 8k lbs, I get 29 mpg on the highway and great torque. Do some more research... Aftermarket filters on Amazon are cheap. Oil changes are quick and easy. Rotella T6 5W-40 is what the dealer uses and its cheap (although hard to find right now). No overheating issues in VA, and I drive it hard all the time.... Off Road and on
Thanks for the info! Think I'll stick with getting the 3.6. The extra torque of the ecodiesel isn't worth all the little hassles to me when the 3.6 is enough for my needs
Liquid-cooled engines don't benefit much from allowing more air into the engine bay. I've been seeing what others have tried and an oil cooler seems to be the best option.
@@Casey250 the i6 engines in cherokees of old benefited a ton from it and the hood scoop on the subarus serves a dual purpose of intercooler but also channeling air past the turbo charger to keep the head and block near it cooler. Might be at least something to try even if its not direct for actual radiator cooling.
Yeah the vented inner fenders really help keep the turbo cooler, mine hasn't de-fueled since. Xj Cherokee's had the same over heating issue's with the gas engine a louvered hood cured it every time.
I'm curious if you're still on the stock 3.73 gears. After driving a JTR gas and diesel, the diesel just put more of a smile on my face driving (I'm a big truck really I am).. So we ordered a Diesel Rubicon and have been happy with it. It makes the 2500ft climb (from 5k to 7.5k) from civilization to our house pretty effortlessly.
I have a 2021 JLUS and love the eco diesel in it! Stock tires it is great for fuel economy. Did a Calgary to Golden then back through Radium to Calgary 900 kilometers at an average of 7.7 liters per 100 kilometers. Just under 8k on it and half a tank of def left in it. Anyone know how many liters the def tanks are on these? And yes the Penzoil is the way to go not the dealerships oil. Canadian Tire or Walmart here in Calgary seem to be the cheapest place to find it often on sale at 20 to 25$ Canadian a jug of 5 liters which I believe you need 9 liters for these engines so 2 jugs will do. Before buying the diesel I did drive all models from the 2.0 turbo, the 3.6 gas and the 2.0 hybrid. I loved the diesel 3.0 the best 👌. And the 1.20 for diesel verses the 1.34 for gas right now is a plus. Had issues with the Uconnect on it many times but nothing else so far 🙏.
On the DEF. When you are off road the fluid is moving around. If the sensor is adjusting for the movement. Could it be like the gas tank. If the fluid goes out the bottom, but the sensor is in the middle when you are climbing or descending down the hill the sensor is going to think that you are almost out. However it should correct itself on level ground. Just a thought.
Girlfriend has a 2014 Grand Cherokee with 3.0 ecodiesel. It's had a few recalls and one was for retuning the ECU due to emissions cheating. Now it has giant hesitation in the throttle pedal response, especially in an emergency situation where you need fast response. Got to take it in for the fifth time now due to the DPF getting clogged. If it wasn't for all the emissions stuff it would be great.
Glad I haven't had ANY of the issues you have had with your diesel Wrangler. I enjoy mine so much, I will be ordering a 2022 diesel JT soon as the new options drop.
Thanks for all the info you provide keep the videos coming. I have a 2021 Rubicon diesel with 5k miles on it only issue I’ve had was the def injector that connects into the exhaust got taken out by a truck tire on the expressway.
In regards to your def fluid, I have a Chevy 2500HD diesel and my shop told me that the Blue def fluid does not work well, he recommended AC Delco! Anyway, there is a UA-cam video on rating different Def fluids, this might solve some of your issues by changing fluids, mine seems to burning cleaner!
Great video....IMHO, way too many issues for a $55k USD 18 month old vehicle. I imagine you would feel differently if it was out of warranty and you had to shell out $4k for the ridiculous exhaust fix.
@@motardforlife2197 deleting what parts though? I think deleting the DEF related stuff is tied to way too many sensors to be worth trying and without getting a CEL. A blocking plate for the EGR seems pretty simple though but probably a computer sensor for that too. Just seems if someone gets a new diesel they bite the bullet, can't believe they wouldn't had known about all this emission crap before purchasing.

You should reach out to Brad from trail recon and see if his Jeep had the same issues with the DEF. I feel like I’ve heard him mention it before
I spoke with the deals, what needs to happen is Chrysler needs to have millions of complains and maybe a few lawsuits before they make corrections or changes. Your laws might be different than CA, but if I have to take into service for more than twice for the same thing and the Jeeps hits at the dealer for 30 days, then I can lemon law it.
I think it is cool that you are completely honest about the Jeep. Many online feel obligated to always be positive. Being fully transparent is appreciated!
Thanks! Just trying to keep it real. When you see something I like you'll know it's authentic as well.
Basically the d e f system sucks and don't go 4 wheeling
Nice vid 👍🏻. We have a 2020 EcoDiesel JL as well. I’m just S of u in Idaho. This summer I noticed the temp of the coolant creeping up high. I didn’t have the engine decrease power, but I didn’t like the temp increase.
An old trick my dad taught me worked: make sure the a/c is off and crank your heater to full hot, full fan with all vents open. Keep the Windows down, unless u like hanging out in an oven😁. In about 2 minutes , my coolant temp dropped about 10°F. It’s not the best feeling in the cab when it’s 100°F outside😆, but with the windows down, it’s tolerable (and just temporary). I only used the trick while climbing over a mountain pass.
It May be enough to let You keep up with the group, keeping the engine at full power, and keep the coolant temp down 👊🏻.
Using your heater core this way is like adding another radiator to expel extra heat while working the engine.
I tow a 5500lb camper behind my Gladiator Eco-Diesel sport lifted 3.5” and 37’s. Over the summer I was towing up a small grade in about 92/93 degree weather and all of a sudden I lost power for a couple mins. It genuinely scared me as I had zero idea what was wrong, but I got over the hill and started down and power came back. I never figured out why and it never happened again so I had forgotten about it until you mentioned it in a previous video. So now I know what to look for. Thanks for this video!
P.S. I’ve got just under 10k miles on mine and I’m about to go put my 4th Def fluid jug in. It tows WAY better than I would have expected with my setup but it just guzzles def fluid while doing it.
Lots of torque for sure on these.
I’m only going to chime in on this for the readers that might be trying to decide if they want a EcoDiesel or the 3.6L. I have to I find Casey’s conclusion contradictory. If you intended on adventuring with your Jeep and want peace of mind, your way better off with the 3.6L. I run 35” M/T’s and have a 2 1/2” lift on my JTR and it’s a dream to drive on the highway. There is literally zero fuel economy benefit from the the EcoDiesel given the premium of the cost of the motor. The DEF fluid issues guys are having is a hassle I definitely don’t want when I’m in the middle of nowhere on a camping trip! And the last observation I’ve made about the Diesel is the added front end weight of the vehicle, if you like to play in the snow in the winter they tend to submarine from what I’ve seen.
From listening to all the issues you guys are having with the Diesels the only benefit I actually have heard is that it has great passing power with bigger tires one your way to the auto parts store to pick up more DEF fluid….just my two cent.
If you want a hassle free experience and want to save a nice chunk of change, get the 3.6L
Range is a huge benefit with the diesel . I have 40” tires and heavy oneton axles on my 21 JLURD . My Jk was getting 1/3 the range with the same mods .
For my benefit only, the ecodiesel meets my company requirements of 27 mpg on the hwy. For that reason alone I opted for the ecodiesel. I get $900 per month for vehicle allowance meeting that requirement.
I spend almost half of what Shaun does on fuel when highway driving to our destinations. Mind you in Canada, diesel is almost always cheaper at the pump as well. Just this weekend, we topped off, drove for about 4 hours, and topped off. Mine was $40, and Shauns 3.6L was $72. Im saving a ton on fuel on the highway.
@@Casey250 Diesel in the north is the same cost, your getting a touch better fuel econ. Most guys here have such terrible issues in -35/40c they exaust delete in the first year after it wont start all winter. Premium engine with premium costs.
@@Casey250 I agree with you on fuel savings. On our trip from SF Bay Area to Colorado and back, we all added up our fuel costs. We traveled as a group and always filled up at the same stations. The other rigs in my group spent $950+ on gas. My total was shy of $450 in diesel. Plus $20 to top off my DEF. huge savings.
Coming from a truck driver, with diesel motors TQ doesn’t get you up the hill HP does, TQ just gets you going. So that explains why the 3.6 is passing you up hills. Also def and diesels don’t like cold temperatures, make sure if it’s going to be in the low teens (inFahrenheit) or single digits to use anti gel so the diesel doesn’t gel up. If your idling or going at low speeds you will have more def use than if your going down the highway.
The DEF tank has a sender just like a fuel tank. If you are rock climbing it thinks it's running low due to the steep angle. For the long haul up highway hills, it's best to manually pull the auto back a gear so the rev counter is around 3,000 rpm. The diesel will otherwise hold onto a gear without downshifting, placing more load on the engine and potential overheating, especially with taller tyres! Thanks
I've also heard there are different qualities of def out there? effecting these issues?
I drive a Semi truck. On my truck I have an auxiliary switch that allows me to manually turn on the engine fan if I need to cool down the engine in the event of overheating conditions. It should be possible to do this on the jeep too. I love your videos Casey and I've watched you for while now. I'm also a fan of The Story Till Now. Thank you for sharing.
Great suggestion, and the Tazer JL Mini lets you do this.
I have 9k miles on mine bone stock so far and zero issues.... I've been in 112 degree heat this summer in 4 lo and pulling grades out of tahoe which is very steep. Not even a degree change in that heat.... no def issues at all. Seems to burn about average from my experience with def fluid in other vehicles. Absolutely love it! Hope it doesn't have the problems you have had.. oh I have a banks tuner, which is the only upgrade so far since all parts are on back order.
It’s the mods that ruin the vehicle and make it where it won’t cool properly. Ask the car engineers, they will tell you that the vehicle was engineer to work best stock. Any mods the average Joe has little knowledge on how that is going to effect cooling, etc.
Please keep showing your Wrangler/Rubicon ecodiesel in your videos, the good and the bad. I’m the only guy for a couple hundred miles that has a ecodiesel Wrangler Willy’s edition 3.0L Turbo. You’re such a great source. You’ve helped me learn about my Jeep make decisions on what I’m doing/going to do with mine.
I really appreciate you sharing your experiences and knowledge with all of out here on UA-cam.
I would recommend using amsoil for the oil, also engine coolant and transmission, differentials as well. This stuff makes everything silky smooth.
I haven’t seen the limp mode issue while climbing a steep grade and I have climbed up steep grades in 100 deg (f) weather while full loaded out. Although, when my 2021 eco diesel JLUR had about 2k miles, it did go into limp mode randomly on the highway on a trip to Colorado (relatively flat section); maybe 4 different times in one day. During that nights camp, I disconnected the battery for about half hour, then hooked it back up. Shortly after that, the uConnect stereo prompted me to do a firmware upgrade (not sure if that was part of the fix) and 1k miles later I’ve had no issues. As far as DEF, I’m consuming 2.5 gallons every 2k miles-ish. No where near what I expected to go thru. But so far, I love my eco diesel. Lots of power and great fuel mileage compared to what I was getting in my 2015 JKUR (13mpg vs 22mpg).
I'm in Colorado Springs and ordered a JLU Eco diesel. Should be here end of October. Went with the JLU Sport Altitude because I like to build stuff out. Glad to hear it does well in the mountains here. I have a 2017 JKU manual 6 speed that I will miss, but i really wanted the diesel. I hit you with a sub just encase i need to pick your brain after my new Jeep gets here.

Few things I'd like to point out to people debating on getting an ecodiesel in general. Having owned a 17 ram. Under 25,000 miles my exhaust and all emissions components (fell off). It ran extremely clean. The tune i had In it produced almost zero soot no matter how much load you gave it. The EPA killed almost all options to do this in today's time 2021. Now knowing the constant issues this engine has been plagued with. EGR failures causing engine fires. Chrysler issiuing recalls on factory tune causing a new flash to be installed basically killing any power the engine may have made before. Severe turbo lag from new recall. Throwing connecting rods thru the block for no reason. Crank position sensor failure. No big deal rite? Wrong. Step 1 pull transmission. They glue the magnets onto a plastic tone ring which is behind the flywheel. And yes they do fail more then it should. It happened to me. Had to pull transmission to change part. Sensors 500 bucks us and tone ring is 100 or so. Plus labor. Cp4 failures from low sulfur fuel ( has low lubricity ). Don't put def in the fuel system. You will need to change everything from it tank pump to the last injector in the engine. Can range over 10k in labor and parts. And warranty won't cover it. It's a user error. Modern diesels aren't worth it to me unless heavy hauling and have a warranty.
Full belly skids are a MUST for the diesels. The stock rubicon “skid plates” don’t cover the exhaust components at all.
I haven’t had the DEF reporting issue, you and I got our JLRUDs around the same time. But like you, I am using more DEF than I expected, about 2x more than I expected.
Haven’t been in the altitudes you’ve been, but never had an engine heat issue and I book over long hauls 75 mph, easy from NY to PA or NY to ME (similar build, 37s, full beadlocks, steel bumpers, fully belly pan, rhino-rack backbone and pioneer platform). When crawling through rock gardens, I get a high steering fluid temp warning every time. I use my Tazer JL Mini to turn on cool-down mode to gulp air into the engine bay and that fixes it.
My biggest PITA isn’t a diesel issue, my JLRUD keeps throwing traction control/ACC errors. I think I have a bad wheel speed sensor. I need to take it in. I know the JKs were notorious for this problem.
You should look into the apex performance power steering cooler. I had the power steering warning crawling with stock tires, installed the cooler and have no issues with my 37s.
@@tomsimard9432 thanks! are you running a diesel JL? Want to make sure it works with them first. Northridge4x4’s site shows it as not fitting, but sometimes that’s just because they haven’t update the site.
Will probably have to find a new location for the manifold, itself. Not sure if that will fit with my aftermarket bumper and winch.
@@jeckart3d I have a warn zeon winch with the factory steel bumper. It is a tight fit and you have to play Tetris to get the lines to align. It also requires drilling a couple holes in the frame. It is like anything else on a jeep, your combination of parts may have different results. I think the biggest improvement is the additional fluid and surface area because I wouldn't anticipate much airflow.
@@tomsimard9432 very helpful, Tom. Thanks! I have a warn winch, too but aftermarket steel bumper. Along with fitment, I also know the diesels have a bunch of systematic differences to their gas and electric counterparts. As long as this system is compatible-I can figure out the fitment. Thanks again!
I've got the eco diesel in a 2016 Grand Cherokee. I've had it back to the dealer 3 times now for EGR recall issues. Once, they kept my Jeep for a week in order to get parts from a dealer in Michigan. Plus, I went through the EPA issue where the fuel economy and performance actually decreased after the reprogramming. I haven't had the Def issue on hot days while climbing grades on the highway. And yes, the oil change is crazy expensive. My wife keeps complaining that the higher diesel cost and oil change cost negates the fuel efficiency gains.
I also have a 2019 Rubicon 2dr with the 3.6L and manual transmission. While the fuel efficiency sucks on the Rubicon, it's still a blast to drive and the oil change costs are 1/3 of the diesel. I'm happy with the 3.6L in the Rubicon and glad I didn't opt for the diesel.
Outstanding review. We purchased an eco diesel about 3 months ago and have right at 5K miles on it. I’m been paying close attention to your videos outlining issues. I hope Jeep can address these and adopt a fix. So far though, we’ve been absolutely loving the eco diesel.
Curious how it'd treating you a year later?
He bought the first year which is a major no-no imho. 1st year owners are essential testers. They really shouldn’t have killed the EcoDiesel. The new full-float axle could’ve made this a towing/highway road trip monster. On Gladiator even more-so…
Great Info. Just got our 2021 EcoDiesel Gladiator Rubicon a month ago. With only 800 miles on it, we set off on a two week vacation pulling a 19’ Aluminum Boat. Pulled a couple passes and was in the desert heat (85-95 degrees) all of the trip. Knocking on wood, had no problems at all. Didn’t have any idea on the cost of oil changes, glad we are a part of the dealer program and the 1st 5 of them are included. I subscribed and will keep following your updates and post if we run into any issues.
I was thinking of buying a 2015 Jeep Cherokee from Carmax in the lower 48 with only 33,000 miles on it (about 53000 km). The car has an open recall for the high pressure fuel pump which Jeep currently has no fix for. Spent about 20 minutes talking to the service adviser at my local Jeep dealer as this too, is an eco diesel. What that means is these diesels are fitted with an EGR (exhaust gas recirculation) system which, as the name implies, recirculates exhaust (soot). Over time this clogs the EGR system and the engine (like one would expect). And causes fuel system failures and all the rest detailed in your video. The diesel exhaust fluid is added nearer the tailpipe in the exhaust and what ever gases are left are burned by a spark plug there. Turning the soot into ash which eventually still blocks off the exhaust system and if left uncorrected, will destroy the diesel engine, eventually.
One need only recall that older diesels in tractor trailers and farm equipment lasted for several millions of miles instead of a 100-150,000 miles before needing major "repairs".
In the states the Supreme Court has just ruled that the EPA does not have the authority to make or enforce law. So, bearing in mind this is a $6-8K problem to "fix" many, including myself, have opted for an EGR delete where the soot is not recirculated back into the engine and goes still to the diesel particulate filter (think CAT). Some folks are just doing straight pipes. And the local DMV in my state has decided to give emissions exemptions to ALL diesels based on the Supreme Court ruling (beginning November 1, 2022) and the fact that the expense of near zero emission for diesel is exorbitant and ultimately, doesn't "fix" the problem. It is an untenable system. It does not work.
The emissions laws in the EU are much more realistic and that is why diesels remain popular in Europe.
For now in North America we are stuck with a dominant political party in California that doesn't care or understand the basic chemical laws of carbon emissions and somehow has managed to dictate their psychotic view of reality to the whole of North America.
A brief look at recent emissions/ green history bears this charge out. In about 2000 there was low sulpher diesel at about 115 ppm. Then in 2010 came ultra low sulpher diesel at 15 ppm. In 2015 or so we saw the first signs that the new stricter standards were not working when VW corporation was exposed commiting fraud with the EPA (since 2009) rather than try to force diesels to be ultraclean with EGRs, DEF, DPFs, burn offs of soot and all the rest. They were fined heavily and withdrew diesels from North America entirely.
Why? Because the two of the three biggest things about diesels that people love about diesels have been taken away by these ludicrous laws. Reliability and longevity. You still have torque, occasionally if the thing is running correctly. Which is only when they are very new and not choking on their own soot.
At this point there is only one solution. Get rid of non-elected organizations mandating unrealistic "solutions" to created "problems" by understanding most of us have to balance the need for clean air with realistic monetary expenditures out here in the real world.
Vote those bums out and vote your self in by running for office. Clean at "any cost" only works for elites like Elon Musk and the IT crowd. About 60% of the population of the United States lives on around $40 K US for a family of four. They're having trouble paying for basics let alone an $8,000 annual "repair" on their tractor, semi or ford F350. So, faced with that reality people are moving from places like California and Washington to states where it is no longer illegal to modify their diesels back to something around 2010, That's the fiscal reality that VW realized. And so are we down here in North Carolina. It is time to say "no".
Hey Casey, great channel.
Just wanted to share with you
I had the same issue here in europe with my diesel 2018 jeep jlu regarding the def warnings. The issue was with the def tank and its sensors not working. Took 9 month to get a replacment tank from Italy but once changed i have no more def issues.
Thanks for another information video on the diesel! I am currently at 10k miles, or 16,100 km, and I have not had many of the issues that you have, likely due to being at a lot lower altitude in the Appalachians.
I keep a small container of def fluid in my Jeep, for peace of mind, when I am in remote locations. This is not only due the issues I have seen with def system but in case I were to puncture the def tank. I could repair with patch or steel putty, then put some def in to hold me over. I plan on putting a skid under it soon.
When available, I may buy the 392 hood with hydro-guide to get enough airflow to avoid overheating. I haven't decided between that or trying to fabricate my own snorkel, since no one seems to want to make one for diesel.
Good call with the extra def small container.
I have the Eco diesel also. I appreciate your videos on the subject. I'm not 100% with it yet for the reasons you bring to light. Please keep up the good work.
Are you experiencing any of the issues Casey is mentioning here? Thanks
10k miles and happy with my eco diesel. Most of my off-road adventures are in western Colorado at altitude. I've got a lift, 35s, and some other common modifications. No roof top tent and other extra stuff bolted to my rig. Mine is not a daily driver and will probably delete emissions after the warranty expires. Nothings perfect but I do feel the diesel hits the sweet spot for me.
I think with a delete this is the best platform in a Wrangler ever.
I want to do the delete on my 2020. It is out of warranty. I filled up the DEF 3 weeks ago and could not put anymore in and the gauge told me I was 3/4 full... No warranty .
Nice that you would buy it again. Similar question is would you keep it when the warranty runs out?
Hard to say. I am already reaching the limits of what I can still warranty as it is lol.
Thanks for the update on your end. I have just over 4100 miles on my 21 JLURD and the engine has been a true pleasure to drive through the Colorado mountains. I plan on adding 37" Mickey Thompson Baja Boss A/Ts (once they arrive) to accompany the Metalcloak 3.5" lift. The MC lift handles the engine weight far better than the stock springs, which I feel like were far too soft. One issue I did have while off-roading near Ouray, CO was running the AC while on the trails in 4 Low. It caused the power steering to throw an error of decreased performance due to heat issues several times. Mind you, this was stock, except for the Falcon 2.1 steering stabilizer on soft.
I have no issues. My friend in New Mexico has Jeep Wrangler Rubicon Diesel. She is always operating at an altitude of 8000 ft. Near the Sandia Mountains, she had cooling issue 2 times this summer. She was going thru a REGEN phase.
I suggested to her to purchase the Mojave/ or the 392 hood. This will help with moving a lot more heat from underneath the hood.
Also suggested cutting out some of the plastic that are in the fenders. Easier for the hot air to escape.
At the end of the Day she went with the Mojave hood. Had it painted to jeep color and it actually looks sharp. tough looking and better looking. and ZERO ISSUES with limp mode or temperature rising.
I love my diesel Gladiator. The torque is amazing when offroad. Have had no issues with it.
Add an engine oil cooler, my coolant temps on my gas jeep ran 18°f cooler
There are a few that have been piecing one together that I am keeping a close eye on.
As I understand it it’s hard to put in oil cooler in there as there is barely any extra room. And people say you don’t want to block more airflow. Thoughts?
I have a 21' ecodiesel gladiator and love it. Plan to leave it mostly stock and hopefully I don't have any of the problems the early one's had. It's been almost 2 years since the gen 3 came out in the Ram. Think they have revised them a bit.
I noticed with mine that low speeds and towing/offroading will consume more def.
I have the ecodiesel but i use eco fuel saving tabs. They improve combustion, give more mpgs, reduce emissions, and less regens.
I also run Amsoil motor oil, engine coolant and transmission fluid..... engine operating temps are down with the Coolant and transmissiom fluid.
Also get a scan guage or scan tool. It can see temps of turbo, dpf, and soot load.
My diesel is supposed to arrive this week and I’m pretty excited. And yes, load on the engine effects DEF is consumed at a higher rate. I’d put it in the same category as gas. Always bring extra, never be unprepared. But once I get mine I’ll be starting my own channel and will be doing intervals reviews on the truck. And as someone who grew up around 1 ton diesels, oil changes have never been cheap. But damn son are they fun to drive! Happy trails, Casey!
First thank you Casey for your content-the worst thing about horror stories is when numerous people are telling them and you're not the only one that has these issues yet your content with so many others helped me decide to not get the ecodiesel, I settled with the 4cyl 2.0t and was somewhat hesitant but it's gives the right amount of torque and no gremlins thus far.
How is the 4 cyl treating you?
The diesel has more drawbacks then advantages. The 3.6l has gotten jeeps everywhere the driver tries to take it. You’re real money will start to come when the warranty is up. To each his own though! I enjoy seeing your build process and your journey with the eco diesel!
Diesel is better than 3.6 in every way I would never go back
I love the idea of a diesel but not a modern one with all the sensors....irregardless of how hard I off road I have experience to many issues with my colorado diesel 2.8 duramax and it just wasn't worth it. The wait alone (mind you pre cv19) was 3 weeks no thank you. Then you have limp mode when these issues happens.
@@justthisguy1948 glad you enjoy it. If it didn’t have all the emissions junk on it, id have one to.
The diesel mechanic in me says buy the gas engine.
@@RiverJunkie too funny, You have the exact same name as my father. I've never seen anybody else with that name
Great Review and this why I even in Germany decided against a Diesel and bought a Jeep where you can fuel Super and Super e10 😉👍
I've done a bunch of different off-roading like you have, but I drive a Colorado ZR2 diesel. I've been from sea level to 13,000 ft. I have 60,000 miles on mine now and literally haven't had a single issue with it. That sucks that the eco diesel is so plagued with issues. I can get an oil filter for mine for $14 US.
I got a gas gladiator for one simple reason. Simple proven engine that’s naturally aspirated, makes more power (not torque), and weights less. Less weight means less stress on the vehicle and easier to make it over obstacles. The power is negligible, but it at least gives it the same capability albeit at higher rpm (not a big deal since rpm doesn’t = piston speed or inertia, a lower rpm longer stroke engine can have a higher piston speed or more inertia than a higher rpm shorter stroke engine). Lastly, the pSTAR is a proven engine with excellent durability. It’s simple and doesn’t have many points of failure.
Very interesting comment and one that I agree with. That said this diesel is is a lot of engine for this application and quite literally fills the engine bay. It's a good option for those needing or wanting the extra torque but utilizing it is a problem. Diesels generate more heat from higher compression. Adding lifts, larger wheels with more negative offsets, larger and heavier tires, heavy aftermarket bumpers and roof racks, winches, lights, and hauling around a lot of gear all puts extra strain on both engines and every part of the suspension and drivetrain. And the diesel itself adds several hundred pounds to a vehicle with that option. Re-gearing is appropriate for either engine but getting rid of the extra heat is one important issue. As I recall Jeep engineers widened the front grill slots on the Gladiator to aid cooling for the original 3.6L V6 engine before the diesel option was even available. Maybe the grill will be widened even more along with the addition of various coolers (if they will fit)?
I'm mindful that Jeep spends millions and millions on testing and engineering to achieve a balanced drivetrain with reliability. Meeting emissions' mandates hampers that goal and vastly complicates the entire system. While I recognize this overheating issue happens on some stock diesel vehicles changing one crucial component like tire size affects many other components as well as performance. Unsprung weight for instance has a geometric impact on performance and an increase in diameter effectively lowers the numerical gear ratio taking either engine out of it's intended power band. I'm sure Casey knows all this and a lot more but is pushing his vehicle for his channel and willing to put up with the compromises. Perhaps the average Wrangler or Gladiator owner would be well served stock or maybe modestly increasing tire size. But we all know that's not going to happen as aftermarket companies are willing to sell product that compromises the original integrity of the vehicle.
@@dantimber my 3.6 Rubi grill has plastic filler so it’s not fully opened up.
.
Torque is great. I had a 12v twin turbo Cummins ram. But for my application it only increases range not capacity and reduces performance with the added weight.
.
If the diesel had a 9k tow rating and 2k payload, then I’d say it’s worth it for the added capacities. For me and my needs the gasser just works better. No turbo lag, deep gearing, and a power train that is easy to maintain and be reliable.
@@KTMcaptain That makes sense. I'm only speculating but Jeep could probably make a number of small changes to increase the towing and load capacity of the diesel engine in the Gladiator like modifying the grill for more air flow and coolers. But that might necessitate frame and suspension components as well as things like the driveshaft and brakes. One change can trigger a bunch of other changes.
But as it stands now I agree with you that the gas engine has advantages that may outweigh the diesel. I'm sure Jeep is well aware of the situation.
I've been using Amsoil Signature diesel oil with great lab analyses from Blackstone. I also order the Wix USA made oil filter for my 2016 Ram, 2nd gen diesel. I change at 10,000 miles. I now have 128K after putting it into service at 700 miles.
A lot of my jeep friends were super excited that jeep was FINALLY going to provide a stock diesel option. Only problem, jeep did it WAY too late. If they would have done it in 07 or earlier, it would have been awesome. Unfortunately, with a diesel these days, the EPA has mandated a slew of changes since 08 that chokes the engine and inevitably causes the buyer money out of their pocket. I have a 2015 ford 6.7l diesel. The problem of having to fill the DEF is the least of worries, quite frankly. Not only does it have the filter that requires hard running for long times to clean, If you don't run the vehicle like that, you'll end up having to replace the filter which is 4-6k. Fast forward to last year when I saw my first jeep diesel vid. Not only did they add that silly front axle separator to save a few MPG, there is a ton of wiring and sensors that are just waiting to get ruined or dirty on the trail and fail. Not to mention the actual DPF and DEF tank to break, hit, and ruin. After seeing that and the lackluster HP/TQ that the diesel provides, I would say get a gasser and install a super charger or get the hemi. Diesels, unless you're hauling horses or campers, are pretty much a pass these days.
This reviewer's take on this diesel is 100% different from what you say. I don't believe you actually watched it or listened to the end question
AZ to Vegas and back with my stock diesel during the last heat wave we had, no temp issues. Kept an eye on them after watching your last video. I do sometimes have a rack and roof top tent that adds a ton of drag and plan on pulling a small camping trailer, so I am a bit concerned.
Loved the torque in the hills, so much better than my 2015 Rubicon on the highway and trails. Would by another diesel in a heart beat.
Ya it rips on the highway when running right.
I save a bunch of money on DEF just getting it from the pumps at truck stops. Usually works out to $2.79 @ gallon USD. Also not dealing with spilling DEF etc.
I have over 13grand on my jt ecodiesel. No a single issue. I use it and have similar stuff you have in California. I love mine. I have 37 tires too.
I have owned an Ecodiesel Ram 1500 since 2015. It has the same exact engine as your Jeep and the same exact issues with the EGR. Let me give you a friendly advice (GET RID OF IT as soon as you can!!!)
1. Those EGRs have a tendency to melt and as a result, engine catches fire. The replacement is super expensive (around 5k US).
2. The oil cooler, over time cracks and lets oil sip into the cooling system.(bad design). It took me about 20 flashes of the overall system to clean it. If this happens, depending on the severity, you might not be able to clean the cooling system well enough to continue using the engine.
3. The RAM had decent sound proofing to make the engine sound OK (it gets louder over time). Your Jeep probably already sounds super loud with that diesel and it WILL get worse over time.
Cheers and happy wheeling. BTW, I have owned a number of wranglers as well, not the diesel ones of course, but the vehicle is no stranger to me.
I have a 2015 ram ecodiesel. I use the k&n oil filter for the last 60k miles. It's 10 bucks with no problems. I now use amsoil heavy duty oil
Experienced the same issue of power and speed reduction due to increased engine temperature.. Outside air temperature was 90 F while driving I-80 eastbound in Nevada. Climbing a long uphill grade at highway speed (70 MPH) the vehicle suddenly reduced power and limited speed.
Really informative and helpful, great work Casey. Good tip on the Pennzoil 5W-40, we'll be stocking up since our Jeep Wave credits are running out soon 🤙🤙
I do my own oil change on my 2016 Jeep Grand Cherokee Eco diesel. I order everything on Amazon and then use an oil VAC-Pump setup. Supply's= Rotella T6 $35 per x2 and 6 oil filter for $34........ all done for less than $100 US Dollars and with the VAC system is a bit pricy, but I've never had to go underneath and pull the oil plug. Super easy stuff.
Casey, I own a 2021 JKURD. Its equipped with an aev 2.5, aev beadlocks, and 37" nitto ridge grapplers. I do feel like the EcoDiesel is ok with the stock 3.73, but I feel like it lugs in 8th gear, and has a little less to be desired.
I was planning on 4.10 gears, but 2K for such a small difference isnt a good investment. The gear calculator shows that a 4.2 ratio will being it back to stock, but with the added rolling mass and heavier items, I believe a 4.56 will be ideal. I wish there was a 4.30 option but nobody makes a 4.30 for the JL 210mm front axle.
What has kept you from regearing and if you did regear, what is the ratio you will likely run?
The Epic Adventure Outfitters blue gladiator has 4.56 gears and yes it will hold 8th gear a little better, I don't find it to be a problem. Fuel economy on the trips we have been on is near identical. So for the money to regear, its low on my list of things to buy.
I have a '21 JLUR ED. I tow a 1,500 lb. teardrop camper and overheated climbing from 9,000 to 11,000 ft. on stock wheels/ tires in July on Colorado. I tried all sorts of things to get to the top, but slamming it to the floor and only being able to go 40 mph was ridiculous. Frustrating for sure.
Thanks for the oil recommendation! I only have 1 freebie oil change left on the Jeep Wave program. lol
Try tuning it lol. You can get tunes for these. I use fuel saving tablets. They improve combustion, performance, made engine quiter, and have less regens.
I've towed up to 7,000 lbs so far with my EcoDiesel no heat issues it didn't even move any pressures or temps during summer but max elevation was 4,000 ft on that trip and no heavy grades. Also 16.8 to 17.7 MPG
i would run a separate transmission cooler and separate the transmission cooler from the radiator to help with engine temps. those tires are guarantee raising the temp significantly.
I have and haul with my Libby crd. Maybe this might help I had issues with Mtn climbing 3 things: 1 - egr to manifold pipe had a crack. 2 - 4 glo plugs bad with 3 rockers replace. 3 - air flow sensor harness bad. 98% fixed and no more over heating. Now I can pass semis and drive in Tx heat, haha with ac on too. ~Christine
I can attest to the def levels. I went off road with just under half a tank, did about 25 miles up and down a mountain, almost ran completely out. Don’t know how the first half lasted three thousand miles.
I've only had one "high heat" issue, we were on the trail for about 3hrs and popped out on to a road that was 50mph, but steeply uphill. It bogged bad and just wouldn't go. The day was 109F at 6500ft elevation. I added Redline Water Wetter, never had it happen again since and we have really high passes (9,000+ft) and a heavily loaded JT-R on 37s, stock gearing, heavy beadlocks, and a 6" lift. Redline Water Wetter.... If you live somewhere hot or climb high passes, add two bottles your coolant, you'll thank me later. The 3.6L guys can definitely run it as well, just go one bottle in your radiator or overflow. If you live in cold temps, water cools better than coolant, so keep it as weak as possible, your comfort level will vary, but Redline + water + a bit of coolant will treat you right.
EcoDiesel powered Jeep....literally nothing better on the trail, so low drama. I live an hour form the Rubicon and I'm up there frequently along with our other incredible trails in NorCal, and they are serious rock crawling. Wouldn't trade it for the world, even a 392.
I've been driving trucks since the 1970s and still to this day. Way back before computers got bolted on to trucks, we had mechanical fuel injection. Meaning, you could actually adjust each injector with a wrench to give your engine more power. This was on a 1976 Mack truck I nicknamed "Flykiller" because of all the black smoke that poured out of the exhaust stack - not to mention all the 10W40 oil it burned. Oh yeah, and no EGR hoses or anything. Any crankcase smoke was vented directly below the engine from the blowby pipe. Polluting yes, but reliable beyond your wildest dreams. Many years later came came DPF filters. First generation DPFs were terrible. They were forever clogging up going from Stage 1 - 2 - 3 - and finally limp mode Stage 4. At this point, your only recourse is to bring the vehicle back to the dealership were they have a special machine to unclog what looks like a coffee can which a bunch of straws inside. I'm not so sure how long your going to keep your Eco-Diesel after the warranty runs out, but it's going to cost you an arm and a leg to keep that thing mobile. Diesel engines are terrific - it's just all the extra, modern junk around it that's the problem.
Waiting for the right rock to knock a few things off ;)
Good info. I will say I pulled my boat (2500lbs) 360ish miles one way across the state of Virginia from the mountains to the Chesapeake Bay there’s two fairly large mountains with long hauls. I was using a 2021 stock jeep wrangler Sahara with the eco diesel and I didn’t have any over heating problems so far but I’ll keep a Close eye on it. This trip is a fairly common trip I do throughout the summer and fall.
Hello, I'm Ralf from Germany. I have a 3.0 eco diesel Gladiator. Weight 2.9t empty and I'm towing a 3t caravan. I also had temperature problems.
Now from an oil temperature of 100 C°, the water is additionally heated via the water oil cooler.
I therefore installed an additional oil cooler air/oil cooler. No matter which mountain I can no longer get above 105 C° water/oil temperature. Material costs in Germany approx. 1200 €.
Casey, thanks for the up date. I purchased a 2021 JWURD and have about 2000 miles on it. I haven't done much off roading yet. Im still getting it ready to go out there. Im going to lead the running gear stock to get a feeling for what it can do before I start upgrading wheels and tires. I want to compare the handling as I make upgrades. I watch most if not all your videos. Keep up the good work.
Good information in your video. Thanks. I’ve had a Wrangler with the 3.8l for 12 years and 182k. My only complaint is the lack of power. I’m planning to get a Gladiator within the next year and really hoping the eco diesel was the right engine choice for me. Glad to hear you would buy it again.
Its definitely fuel-efficient and plenty powerful when you load it up with gear and mods.
Just a heads up. Most of the harnesses connections in the ecodiesels are the weak point. The techs aren't trained how to diagnose them so they throw parts at it. I've had to disconnect, reconnect, and wire tie most connectors in the main harness on my Ram. Cleaning soot from your MAP sensor is a maintenance item unless you tune it. I use GreenDiesel tuning in my Ram.
Good info - I am looking at an eco-diesel now so will be using this in my negotiations.
I wonder how Jeep tuned the EcoDiesel engines? This generation of EcoDiesel has been pretty rock solid in other countries, as well as with the RAM trucks. That covers quite a lot of brands that use the VM Motori EcoDiesel.
Either Jeep has tuned it in some funky manner, or it's a combination of how Jeep uses the drivetrain.
With the amount of torque that it has, it really shouldn't be overheating when driving on a paved incline road. Something isn't right.
I love my 2018 JGC EcoDiesel, haven't let any of these caveats bother me. Cheers!
I was excited when I heard they were putting the diesel in the Gladiator because I wanted to do an Overland build but still tow a 5000lb camping trailer to use as a base of operations.
Your pros are compelling, but not enough to outweigh the cons that can leave you stranded on the trail or overheated at the side of the road.
My Power Wagon with the 6.4L on 37’s loves the gas and only averages 12 mpg but it hauls everything I want and is never lacking in power.
I think a Gladiator Rubicon with the 392 is the only thing that is going to get me out of the PW.
In all fairness, even with a broken emissions system, and guzzling DEF, I've yet to be stranded anywhere.
Casey, I saw the original video when you had the over-heat issue. It appears that Jeep has undercooled their diesels for high workload environments. Maybe it is time for an external oil cooler, power steering cooler, and/other aux cooling ? Or maybe it is just as simple as a change of the engine thermostat to a lower value for summer or hi-temp environs ? GL and please keep Casey-250 nation updated.
I know a few people working on an oil cooler. That i feel would make the biggest difference. The ecodiesel in the jeeps is the same as the ram, but detuned for less power because of cooling issues.
@@Casey250 It's just that the Jeep does not have the engine room or grille needed to support the ED. Jeep should have put a different grille in it with a larger front fascia. The Ram has no overheating issues. I know that the 2024 Jeep has a new grille with more airflow. Maybe replace yours with it?
1st, thank you Casey for this super informative video. Curious, do you use any after market monitoring like Banks datamonster or Edge cts2? To keep an eye on regeneration cycles, miles between regens, watching exhaust temps/idling down for safe shut down etc? I'd be very interested in your feedback on that as I've often wondered how the ecodiesel handles regens when the Jeep is used at slow speeds over great distances off road.
I'm waiting for the release of the 2022 model year to place an order for my wife. We will also use it at times to travel long distances from South Carolina to CO, UT, AZ etc. Towing our Patriot Camper X3 (gross 3,500lbs). Strictly overlanding stuff, no rock crawling. Even though I'm a diesel guy, I've even looked at the 4xe as an option to avoid all the EPA mandated crap and the issues potential that comes with it. Thanks for your time
Depending on how you were loaded down, the the cooling issue could be that you were driving so fast up those grades. The auto industry sizes the radiator and fan based on going 45 mph up a 13 mile long, ~6% continuous grade in Arizona at 38°C, fully loaded to GCW with a trailer. So if you were carrying a lot and trying to push ~80mph up a steeper grade you probably were de-rated. If you don't have the heavy duty fan from the tow package it's not a surprise at all. Also, 118°C is a de-rated temperature for most vehicles because that's the point where the coolant starts to break down.
Also, the DEF level issue could be from driving at an extreme angle for a really long time, or if you parked and idled on an angle for a long time. They put some heavy filtering on the level signal from the DEF tanks and it doesn't update quickly like a fuel tank does.
I’m always grateful to hear other’s stories about why you should avoid abusive long term relationships with Stellantis.
thanks, temperature concerns hopefully get addressed by Jeep!
I have a 2019 diesel 2.2 multijet and in that 5 years of extreme wheeling I had NO issues with the DPF / AdBlue system and wiring etc. My car runs almost the identical system as the 3 liter Eco.
PS, in Australia we can fill up with AdBlue at the Gas station from a bouser.
Just picked up a new eco diesel wrangler this past weekend
This is hugely important information! Thank you for sharing this.
Very cool video. Just bought a 2020 EcoDiesel Unlimited Wrangler. Love it. I'm strictly on road so far and found the same regarding the DEF levels. All over the map.
I have a 2020 Gladiator and thought I would get a new one with a diesel but after watching this I’m going to keep what I have , thank you for sharing this 👍
Thank you for sharing about your ecodiesel
the "derating" and overheating you mention is due to the emissions systems you mentioned earlier in the video. You simply cant have a healthy functioning diesel with emissions attached. Modern emission requirements are too tight for any diesel system and is the major flaw of EGT temps and intake pressures. In order to truly open up the eco diesel it needs a DPF, EGR delete with exhaust and intake mods followed up by a tune.
My Multijet 2.2 JL Rubiconwith 37s it runs cool on the trail even when we get 40 deg C days. I also tow a 2.5 tonne van on 2 hours drives when camping and I have no issues
Mine has overheated and shut off numerous times. First while using cetane booster, second when towing my 6000# camper. Turns out it was overheating meaning over 1500 degree egt temps. I have since getting the banks iDash and derringer and now I can watch my EGTs and I can tow my camper at 65mph without overheating.
I think I’m glad I have a 3.6 now. Even if someday when I do upsize my tires I have to do other changes
I haven’t seen either of these issues with my JT and im on stock gearing with 39” tires. Jeep gets 23 mpg and I use a little less than 2 tanks of DEF per 10,000 miles
My Wrangler diesel has alot of the same issues his does. From what I’ve seen online, it’s about 50% of the first adopted ones. My 35 nittos and a 2.5 lift no armor or rack rubicon nets me about 18.3 combined and 3000 miles per 5 gals def.
@@Maistro69 thats a big difference. My odometer and speedo are dead on. I do add 2oz hot shots EDT at every fill up
@@mattbrew11 I have come to think part of the problem is the turbo doesn’t always kick in. Some times when I’m accelerating I get like 3mph and others I get like 10. It’s wildly inconsistent. Also, randomly, the thing will like flat out act like it’s in limp mode when accelerating with a massive delay and no power even foot to the floor and then all of a sudden out of no where kick in and have power enough toe spin 35 MTs. Almost like the computer didn’t know what to do with the throttle valve.
So far, I’ve had the system fleshed. Tried removing my tazer mini, updated the tazer mini, and just recently they issued a service order for a system update to “fix a performance issue” I have noticed a slight improvement in consistency after that and haven’t had the acceleration delay after that. On a side note too, I’ve noticed my best MPG is at 45 mph. I can easily get around 27-32 mpg depending on incline when doing that. Which is weird to me since 65 nets me around 20 mpg.
I’ve also had the overheating issue mentioned in the video. Happens to me when going up long steep inclines like mountain passes.
I have the 21 JT Rubicon eco diesel with about 4,000 mikes. Labor Day weekend, I did have the engine get warm as well crawling in the passes of Colorado in the Ouray/Silverton areas. The power steering light came on. We pulled over one time knowing that we still had plenty of trail ahead at low speed. I parked into the wind and opened the hood in 60 degree weather. It cooled down in about 10-15 minutes. Second time a day or two later, we had open trails ahead and picked up the pace and the light went away. Still in love with it, but definitely looking to reduce the heat under the hood.
I did over heat the power steering once as well. I mention it in one of my recent videos in the Rocky Mountains.
Casey - what are your thoughts on the 2021 and newer change in grill (they have the larger holes). Is it because they wanted to use the same design used in the JT so they could add a camera or that the diesel needed more air flow?
Long time follower as I also own a 2020 and just wanted to see if you had a comment. Thanks
It has nothing to do with the cooling. Cooling issue exists even with the inserts completely removed.
I have a 2014 ecodiesel summit wk2, I did put a gde tune in it when they destroyed it with the emissions mod, but I love this vehicle. It's a beast. I can tow almost 8k lbs, I get 29 mpg on the highway and great torque. Do some more research... Aftermarket filters on Amazon are cheap. Oil changes are quick and easy. Rotella T6 5W-40 is what the dealer uses and its cheap (although hard to find right now). No overheating issues in VA, and I drive it hard all the time.... Off Road and on
Thanks for the info! Think I'll stick with getting the 3.6. The extra torque of the ecodiesel isn't worth all the little hassles to me when the 3.6 is enough for my needs
Do you have vented inner fenders for the heat they also have aftermarket vented hoods.
Liquid-cooled engines don't benefit much from allowing more air into the engine bay. I've been seeing what others have tried and an oil cooler seems to be the best option.
@@Casey250 the i6 engines in cherokees of old benefited a ton from it and the hood scoop on the subarus serves a dual purpose of intercooler but also channeling air past the turbo charger to keep the head and block near it cooler. Might be at least something to try even if its not direct for actual radiator cooling.
Yeah the vented inner fenders really help keep the turbo cooler, mine hasn't de-fueled since. Xj Cherokee's had the same over heating issue's with the gas engine a louvered hood cured it every time.
I'm curious if you're still on the stock 3.73 gears. After driving a JTR gas and diesel, the diesel just put more of a smile on my face driving (I'm a big truck really I am).. So we ordered a Diesel Rubicon and have been happy with it. It makes the 2500ft climb (from 5k to 7.5k) from civilization to our house pretty effortlessly.
I had the same issue with the over heating. I opened my hood vents up and that seemed to do the trick. however, my engine does gt dirtier faster.
Thanks for your insight! Did you have to adjust anything to add your 37's?
Lifted it
Thank you for sharing. The more I research all the engine options for a Jeep I plan to order.. the more I seem to come back to the 3.6.
I have a 2021 JLUS and love the eco diesel in it! Stock tires it is great for fuel economy. Did a Calgary to Golden then back through Radium to Calgary 900 kilometers at an average of 7.7 liters per 100 kilometers. Just under 8k on it and half a tank of def left in it. Anyone know how many liters the def tanks are on these? And yes the Penzoil is the way to go not the dealerships oil. Canadian Tire or Walmart here in Calgary seem to be the cheapest place to find it often on sale at 20 to 25$ Canadian a jug of 5 liters which I believe you need 9 liters for these engines so 2 jugs will do. Before buying the diesel I did drive all models from the 2.0 turbo, the 3.6 gas and the 2.0 hybrid. I loved the diesel 3.0 the best 👌. And the 1.20 for diesel verses the 1.34 for gas right now is a plus. Had issues with the Uconnect on it many times but nothing else so far 🙏.
And farm diesel is consistently cheaper for a go-fer vehicle
On the DEF. When you are off road the fluid is moving around. If the sensor is adjusting for the movement. Could it be like the gas tank. If the fluid goes out the bottom, but the sensor is in the middle when you are climbing or descending down the hill the sensor is going to think that you are almost out. However it should correct itself on level ground. Just a thought.
Girlfriend has a 2014 Grand Cherokee with 3.0 ecodiesel. It's had a few recalls and one was for retuning the ECU due to emissions cheating. Now it has giant hesitation in the throttle pedal response, especially in an emergency situation where you need fast response. Got to take it in for the fifth time now due to the DPF getting clogged. If it wasn't for all the emissions stuff it would be great.
Got a ram rebel ecodiesel. Need the extra towing. No issues!
Glad I haven't had ANY of the issues you have had with your diesel Wrangler. I enjoy mine so much, I will be ordering a 2022 diesel JT soon as the new options drop.
i was thinking of buying diesel but now thinking getting 392
Thanks for all the info you provide keep the videos coming. I have a 2021 Rubicon diesel with 5k miles on it only issue I’ve had was the def injector that connects into the exhaust got taken out by a truck tire on the expressway.
Curious, I just bought 2021 jeep exciting diesel gladiator. When u bought urs, was jeep offering u the heavy duty cooling system?
In regards to your def fluid, I have a Chevy 2500HD diesel and my shop told me that the Blue def fluid does not work well, he recommended AC Delco! Anyway, there is a UA-cam video on rating different Def fluids, this might solve some of your issues by changing fluids, mine seems to burning cleaner!
Have you re-geared for the 37s? I wonder if that would help reduce the load put on the motor and help prevent overheating
No but the gladiator with us was, and had the same issue
Looking to purchase an ecodiesel gladiator in the not too distant future. I appreciate all your input.
Great video....IMHO, way too many issues for a $55k USD 18 month old vehicle. I imagine you would feel differently if it was out of warranty and you had to shell out $4k for the ridiculous exhaust fix.
Doubt it.
Do you have to add any oil in between oil changes and curious on how many Kilometer intervals before you change your oil. Thanks!
I change it when the gauge says to. Haven't noticed much oil burn off.
In regards to the oil filter I get aftermarket one autozone for $9 and its the 10k mileage 1.
“But, we just can’t talk about it”…😂😂🤣 Best video outro ever! BTW - transfer case swaps are EPA approved….wear that diesel out and get a 392.
I liked that too "just can't talk about it" 👍🤟👀
I think he was referencing deleting.
@@motardforlife2197 deleting what parts though? I think deleting the DEF related stuff is tied to way too many sensors to be worth trying and without getting a CEL. A blocking plate for the EGR seems pretty simple though but probably a computer sensor for that too. Just seems if someone gets a new diesel they bite the bullet, can't believe they wouldn't had known about all this emission crap before purchasing.
@@BennyTygohome The entire emissions system ;)
