Any engine that requires that much concern ain't worth spit, IMO. I love Jeeps and have had 5 4.0s that would have kept going if other things didnt happen. Seen many a "deal" on the 4.7s, and sometimes its tempting, but common sense keeps from a rue the day scenario. I do wonder about one thing though, concerning the cooling fan. The 4.0s have a bolt on version, which is part of the tow package. I added one of those when my electric fan went out and it was the best thing I ever did. Never had a cooling issue after that. Does the 4.7 have a towing package where a fan is added? If so, that might solve all problems related to hydraulic fluid/ power stirring pump scenario - or at least be a back up.
Not really. The hydro fan is considered “HD” by itself. The 99’s had a mechanic fan/e-fan combo before the hydro which is better BUT Chrysler discontinued the parts used so you have to find one in the wild. Not easy as the 4.7 wasn’t popular in 1999 being the first year used.
As for the engine being too much bother to deal with…. Maybe. Haha. Let me preface that I plan to be buried with a 4.0. Hands down my favorite engine because it has EARNED my respect. Amazing piece of iron… BUT it has limitations - specifically the trans it was paired to in the WJ - which the 4.7 fixes. A 4.0 WJ is a bad tow rig. Sad, but true because of the 42re. Also being a more modern engine there is more ability to tune if that is your thing. As a last note.. I am neurotic about my 4.7 and made this video for others like me. Who want to know every quirk and issue. Most drive them for years without knowing about or encountering any issues.
The tow package includes a power steering pump contraption diverter that spins the cooling fan. The engine must be running for it to operate. Mine is well balanced you feel nothing in the steering or feel and the fan speed is directly proportional to engine rpm. The hydro fan is legit. It's only two extra lines and reliable, removing the radiator is a snap, it's a tight fit but stuffing a V8 into a sub-3900lb SUV equals fun to drive. A couple cheep mods and you're at 260 275 hp and 300ftlbs torque. When I'm streeting it I remove. The front shaft and smoke a 01 mustang off the line

Amen to that. that engine is Like a troublesome woman. Just buy a dog and die happy. LOL
Really can't relate. Have a 4.7 sitting at 325k and all I've had to do is fix the attachments that naturally wear out. Love my H.O. block
If you love something you take care of it. If you don't you move on. Just say you don't like jeeps.
I really do believe these engines are some of the most under appreciated engines to ever be created just because of how complicated they can be. But I still love mine and I hope to keep it running as long as possible so thank you for this video
I love mine, but man has it been a journey to truly understand it. The 4.7 is not for the faint of heart, but you will be rewarded if you take the time
FYI for everybody out there with a 4.7 L W J, the fuse for the O2 sensors is the same fuse for the hydraulic fan relay. Found this out the hard way when I changed out my O2 sensor and didn't put the wiring back where it belongs and it shorted out on the exhaust, blowing the fuse, and making the hydraulic fan stop working thus overheating by engine.
You won't believe how perfectly timed this video is - almost destroyed my 4.7 today! I'm paying close attention.
Yikes! Hope something in here helps! email us if you need help dandeoffroad@gmail.com

Maaaaaan, I've got to ask. How do you keep that beard so luscious?
Just destroyed mine a week ago! Got another getting put in as we speak
Same, we unfortunately did destroy our 4.7 a while ago but when the new 4.7 gets installed we aren't making the same mistakes
I'm going to look at a 2005 Jeep Grand Cherokee to buy Monday.
It's a 4.7L V8.
THANKS for this info, super helpful.
Awesome video. I recently purchased a 2004 Durango with a 4.,7. It runs great but after watching all the u-tubes and researching this engine, I decided to get some gaskets to seal up some leaks, especially the valve covers. Getting a little carried away I thought I would get a water pump and serpentine belt as I don’t know the history on this vehicle. So i decided to go a little farther and I pulled the engine out. (I am retired so time doesn’t matter to me:). Anyway, on the back side of the engine it states the engine was rebuilt in 5/14. I had checked the compression before removing the engine and it is between 160 to 170 dry. my vehicle has 123,000 miles. So now I have a new oil pump and decided to remove the heads in order to inspect the valves and seats. All looked fairly clean but I removed all traces of carbon. I replaced the valve seals springs and lifters. the lifters were showing wear as the springs inside were very weak. I am now in the process of replacing the cylinder heads. I also purchased a complete timing chain, guides and gear set as the lower guide was broken.I am replacing all fluids with synthetic oil, Orange coolant as it was green when I got it.
I feel confident that it will run well and with care will last me a very long time. I pretty much have lapped in the valves and replaced all worn parts but did not get into the pistons, connecting rods or crank as it did seem to run good and with the rebuild in 2014 I am confident that the rotating assembly is ok but now I have peace of mind that the rest of the engine will perform and last. (I Hope)
Thank you for inspiring me with your video, oh by the way, my Durango does not have the hydraulic fan assembly, thank God!
Absolute legend , reminds me of my dad
I was wondering how your Durango is running now after 2 years.
I’m thinking to replace the lifters and springs in mine
1 owner 06 dodge Durango SLT AWD 4.7.
I have 180,000 miles on it, it came with green, I only use green.
I have replaced the tires now 4X.
Replaced the water pump in 2016, all new rotors & brake pads and spme lines in 2017, EGR valve in 2018, and speed sensor last month. Everything on the truck works, every button, it just has two rust spots that keep growing. Been one hell of a good vehicle. Im going to rebuild it all and fix the body next year, and keep it. Love the ride, and heated seats....
I did upgrade the air intake and had it retune when it was new.
Very happy with this truck.
Had my 4.7 ram for just over 5 years. Relatively "low mile" at just over 150k. Had many issues with the cooling system but to be honest, the best, I guess you would call it "upgrade" is a mishimoto thermostat and rad. Im sure the rad doesnt matter as it is oem style, but the 10 degree colder thermostat honestly woke the engine up. It used to get up to temp and pretty sluggish, but that 10 degree difference keeps it pretty happy even after an hour or more on the highway. I would recommend this for anyone that lives in a hotter state, (im in houston) as it keeps the engine much happier. When its pretty hot out these engines run hotter than usual and this keeps temps down.
I also found replacing the ac fan with a more powerful one and switching from a steel clutch fan to a aluminum one helped alot too.
Maaaaan. I just replaced my thermostat a couple months ago. I wish I knew about the mishimoto!
@@HbEthan. where did you get yours?
What ac fan did you use?
Where did you get your thermostat at?
My 2003 Durango had the 4.7 V8 - Used it to tow my race car from Florida to New York to Wisconsin to Kansas for 15 years and 360K miles. Never had any issues except for a crank sensor and several vacuum hoses drying up and cracking.
I am curios what maintenance you did on it? What oil and filter and how often you changed.
I had a couple of wj s with the 4.7 and 4.7ho. Used in hot scorching heat and winter. Zero issues with cooling system as long as you change the cooland correctly, it is a well designed system. People that complain are just abusing the 4.7 and then complain about them.
You can't make enough vids on the 4.7 cooling system! Lol. the more I learn the more I'm terrified of digging in to that WJ. I'll totally be picking your 4.7 brain!
Gotta new radiater after going to fast down I 85 one morning,it said ding!!!! check gages!!!
Honestly these procedures are like any other car lol
I appreciate the coolant filling tips! This video made me feel a little more relaxed about my 4.7l cooling system as it has a mechanical fan. At 135k miles right now and still running strong! hope to make it to 200k+
Uk viewer here man. Love your videos. I have the 4.7 in my WJ and I love it. The UK versions haven't had the type of abuse I see the American Jeeps take, but they are still vulnerable to poor maintenance. Mine has thankfully been looked after and soon as I got it I did a full system flush and made sure it was working properly. That was all thanks to your videos on the cooling systems and what to look out for. I've had no issues with the engine or the cooling since. Great advice and information bud. 👍
Hey I really appreciate you taking the time to share what you’ve learned. New to the car and your vids definitely give me a leg up on staying ahead of problems. Keep it up
Love my 4.7 in my 2005 dodge durango didnt have cooling issues till I repalced the rad. Now I am just chasing an never ending issue with overheating but watching you and learning is awsome love it keep it up
My bro, I have an 02, 3.7 KJ and your videos have brought sanity into my life, having felt like the gremlins that attack these motors were just attacking mine lol! Thanks for these videos and sharing your DIY expertise.
Love watching every bit of the motivation of you videos. I look forward to every day I get record my own life and repair my trucks ( 98 dodge Durango 4x4 and 318, 99 Tahoe 4x4 and 5.7 , 05 Chevrolet Avalanche and 5.3 ) I post my day on my channel everyday. OOOOOOOO I can't wait to show you what the future holds.
First and Foremost thank God for guys like you and Martin Built !!! You guys have been a tremendous help while battling my 4.7..Plus Glad too see this post to confirm my sanity after battling the cooling system on my 02 WJ 4.7 for almost the entire 5 years I've owned it..Extremely Temperamental is an understatement.....Feel like I could write a book on what all ive done too my Jeep within the 5 years I've owned it but love my Jeep and felt its was worth fighting for..... So far this Jeep has been through 3-4 t-stats,Water pump ,Ate a few spark plugs, then started getting a constant misfire on #2 and sometimes multiple cylinders miss which took me nearly a year to finally figure out that it was my harmonic balancer failing/coming apart.. it finally exposed itself when a piece of rubber from the damper created a ticking noise one day while running but when you shut it off it looked normal..So since our local repair shop wanted nearly $800 to repair the balancer I did it myself with the help of a good friend whom is a mechanic...I decided to swap in a new Denso radiator since the Hydraulic fan had too come out and my Jeep has over 200k on the clock...Was definitely hands down the hardest swap me or my friend had ever done..He thought it was gonna be a piece of cake and boy was he wrong...Took us an entire weekend to complete ..... So my next upcoming projects on the Jeep are fixing my stripped purge screw, swapping out hydraulic lifters to remedy the lomgtime cold start tick, along with new VC gaskets, plus the Martin Built PCV mod.. I recently found a severely rusted brake line on the rear driver's side before it drops ontop of the axle, while up underneath looking at my E- Brake cables in preperation to fixing that..I'll get her sorted tho ....Excuse my rambling but I wasn't joking when I said I've been battling this sucker..Lol...Question for ya.. What oils are you running in your 4.7 ?
Thanks for the solid info in this video! My first 4.7 WJ dropped a valve seat and I drove it 50 miles home on 7 cylinders (LOTS of blow-by) before it went bye bye. I bought my second 4.7 WJ a few years after that it's doing alright. I'll never get over that fear of dropping a seat though. I am considering doing an electric fan conversion because im worried about the reliability of my power steering setup (service history shows the previous owner swapped the power steering pump so that scares me). Other than that, I freaking love 4.7 WJ's, sometimes you gotta take the good with the bad.....If I get REALLY pissed, i'll buy a 4runner
That’s why! My friends all looked at me weird when I bought a2001 Durango. I see why. I will pay attention. Thanks man.
I have owned (3) 4.7s with over 600k miles between them. People who say these are unreliable make me laugh.
Thank you for all your knowledge and wisdom I'll be putting it to use today because of course I look into my Jeep and it has the lime-flavored coolant
Great job explaining to folks not only the importance of burping the cooling system, but the proper way to do it as well. I have tried many times over the years to let the damn thing idle until the thermostat opens and the heater is blowing warm air and temp gauge is where its supposed to be blah blah blah! Then you stare into their vacant eyes and think, well someone's going to need a head gasket soon! Some listen but most just shake their heads at me like i am stupid and they are humoring me so I'll stop talking.
Finding WJ's not rusted to death with a 4.0 by me is getting nigh impossible, so i was actually considering breaking down and just getting a limited with a 4.7.
This video certainly cured the urge.
Yes I had 34.76 put in my truck they all went within a month now with the new motor the power steering went and they didn't bleed the system right thanks to you video I'm back on the road thank you very much
I’ve owned at least a hundred Chrysler vehicles with 4.7’s. For the most part, I’ve had very good luck with it. I agree that it takes careful maintenance to keep it running.
why have you had so many? do you run a fleet?
I really appreciate your dedication to this I'm a 4.0 lover about to buy a 4.7 so I'll be subscribing
Good luck! Feel free to reach out if you ever need help
I learned all of this along my journey with the 04 overland as well. My plan: I've got a brand new rad with hydro fan and brand new pump sitting on the parts rack. Next is the 08 intake manifold, ported headers, ported exhaust manifold, high flow cat, and downstream deletes!!! Oh, and a trip to Raleigh on the trailer for a hemi fever tune. I take my wj on some remote trips and have no choice but to learn everything about it because help will not be coming. You definitely built my confidence when this all started a few years ago. Thanks for what you do.
I love my hydrocooling fan in my 02 overland and i don't care what u say about it. Ive never overheated ever and it is a solid setup that never failed on me. 14 years of ownership and 188k on the clock and i love it. We all know how grands are with the e fan and faulty resistors and overheating lol. To each there own. Great vid
Fair enough, bud. My experience has been poor, but I am glad to hear some folks are doing alright with them
@@DEInTheGarage im a firm believer that fan is the reason it's still on the road. Ive seen many v8 and i6 cooked because faulty electronic fans. If you maintain the system and do what i did and run a bigger hyro oil cooler its just a trouble free design and really the only system in my jeep that hasent failed once unlike every other system.Don't blame the Germans..toyota used that same fan idea in the early 90s lexus so it's nothing new.u could swap it to whatever u want and sell that hydro setup because its desirable to alot of enthusiasts for off-roading
@@---skynet--- they switched to electric for a reason lol
@@zachs.9600 electric fans are way more cost effective as far as manufacturing goes.
Thank you for sharing your experience and knowledge with us. My wife drives a '03 Durango we purchased in '05. My pastor had a '03 Dakota in which the water pump failed in 2012 around 100K. Ours was at 108K at that time. A mutual friend changed his pump for him. Our friend changed our pump just as a preventative measure (for $30 no less). In 2013 at 116K miles I changed the radiator hoses. In 2017 at 139K miles the the radiator started weeping. I changed it myself. The engine has NEVER been overheated and is not used for towing. We have always used the green stuff because I didn't know. I am not sure what was in it originally. Here now at 155K and 2022 the 5 year old green coolant looks fine. As far as maintenace goes, I have only changed spark plugs twice the whole time I have owned it. I did have to replace the A/C compressor and drier last year (Thanks RockAuto!). The oil has been changed religiously every 3K since we have owned it. A couple of years ago I changed all the fuel injectors just because. This has been a very reliable rig. Heck, I have had the battery last 8 years, twice in a row.
My 2003 Dodge Dakota 4.7 Magnum has just past 271,000 miles still running great. No engine issues other than regular maintenance. It is going through a quart of oil occasionally but with the mileage who could complain. These are pretty common trucks in my area and i have seen several in my local shop getting engines replaced. As for mine it gets good maintenance never have much of a heating problem except when coolant level gets a little low. That's easy to remedy by just adding a little coolant usually about a quart. The key is keeping fluids checked and changing oil at no more than every 5,000 miles if using a synthetic oil if regular oil i advise changing every 3,000 miles.
Thanks so much. A ton of info I will apply in the morning. Hopefully my cooling issues will finally be solved. But first off to the parts store to get orange juice...
Grooms Engines did a big write up on why the 4.7 is so bad and it comes down to cheap valve seats. Worth a read. You can make any engine reliable if you fix enough design flaws.
Valid. haha
Stumbled across your video, and i already love your style. Been thinking about one of these in a truck, to pull a camper, even though my Jeep 3.7 blew up idling on a very cold day last year, in the parking lot at work . So, i am nervous about any more Chrysler engines !
Just got a 2000 Dakota 4.7. I've owned two Durango's before this, a 4.7 and a 5.9, both I felt were great trucks. Seeing this video now I'm happy I've kept up my love for Dodge because like all cars/engines, they need to be treated right or they won't last. My 2000 Dakota history has me as 4th owner and at 155k miles I plan to keep her running like a champ. These tips will definitely be useful, thanks for the video!
My 2000 4.7 Dakota just hit 301k on the original powertrain, maintenance and not driving hard seems to be the key.
I wish I would have known about you earlier this year before I got rid of my 2013 Ram 1500 4.7. Great video
Excellent video! Straight and to the point with humor to keep it entertaining.
Glad you enjoyed it!
Hey big thumbs up man ! 👍😎
I just got caught by this video and i really love the way you explain everything . As a learning from my cars guy , it is helping a lot ! Good continuation !
By the way .. i drive a 2006 4.7 Jeep Commander ( touching wood ) no eat problem !
Hey boss, I just want to let ya know you saved my ass. Much love brother. Thanks for the great content!
Glad to hear it!
These videos are SO AMAZING. So glad I found this bc he did not use the orange coolant. So when I flush it, I will replace the thermostat in it as well. I do not tow anything but a small flatbed. I will look into the cooling fan system
Glad I could help!
I’ve got a 4.7 in a 2000 Dodge Dakota. I haven’t really had any cooling issues with it ever. 152k and still going. Thanks for the video
2005 dakota and same thing never had a issue. I think it's mainly the jeeps and other suvs because there so tucked in and just bake themselves
I too noticed the belt routing, this will spin the water pump the wrong less efficient direction. I have had good luck filling the cooling system using the bleed port with a transmission funnel when air free coolant comes out of the rad. cap you are done. Nice video, good information.
Bought my 4.7 l wj for 850$ driven 12000 miles still running strong like you said hiccups in the cooling system but great car reliable and cheap to fix I recommend the 4.7 if it’s been treated properly
Dad did a mechanical fan and a 4.0 e fan in his WJ. Flawless performance
I've only owned the 3.7 but yes, it's temperamental. But after going through 5 or 6 of them I've finally taken a liking to them.
I love the new flag design!! I saved all this 4.7 info for a friend. Hope you have a great 4th of July!!
I just purchased a 2006 Jeep Grand Cherokee Laredo 4.7 Car fax shows one owner. Proper maintenance. 104k miles. Hoping it treats me well. I want to do the same so here I am. Thanks for the video.
Just bought an '02 Dakota this spring with a 4.7. I had no idea about the potential problems until recently. Glad I found your channel. It runs great but I'll be keeping an eye on things a little more closely now.
Ive owned 3 4.7s none ever had issues. 600k miles between the three of them. Most reliable motor ive ever owned.
@@clarda1 nice got any videos
5 years ago I purchased a 2000 WJ GC with an apparent engine tick. A massive discount due to a spun big end bearing and a new reconditioned engine, it has been running strong ever since. I was meant to be a launch car for my boat but its such a nice car in very good condition I use it for long drives. Its not my daily. I installed a double row all alloy radiator and ditched the mechanical fan.
The AC Electric fan was re-tuned to run as the engine cooling fan and it works a treat. No cooling issues at all. The green coolant was replaced with red/orange coolant with the new engine.
Sounds like you built a beast of a 4.7!
Looking to purchase a 2007 grand cherokee 4.7. Watched this video and I have to day...you definitely got another sub from me. Cramming my head with info. Much appreciated!!
Thanks for the video, i have a jeep and a durango, i use a plain old clutch fan on both and a lower temp thermostat, all is well! Also i use the bleed port to help fill the timing cover after filling the radiator. Finally, I use green antifreeze, knock on wood, but it has been good so far. I was nervous about buying a 4.7 truck as well, but now I have great respect for it, the biggest thing about these is don't use cheap aftermarket parts, especially the timing system and valve train!
The green antifreeze will cause corrosion in the aluminum engine, that is the reason for the different color antifreeze that is formulated to not cause corrosion to aluminum.
I know this video is 3 years old, but I have a 2010 Dakota with a 4.7. Fully stock and towed a 3300lbs Rpod around the country, through the mountains of BC and Yukon, Canada, and then up to Alaska where I live. after 173,000 miles I've had zero issues.
My 2013 (same exact engine as yours as its post 08) just failed @ 166K.
@@TheSavage3.6 shit sorry to hear that!
@@davidsmith9 Yeah, funny part is that i can’t even figure out what’s wrong with it lol.
@TheSavage3.6 man... are you putting another engine in? Mine is in such great shape I think I'd replace the engine if it went.
I literally did my whole system except the core for my 04 Ram! I'm on my 3rd water pump, two since I've owned! The front end suspension is money!
Just added new mechanical fan and electric fan factory tow setup to my Liberty. 15 minute job. Keeps its cool. Good insurance.
Damn glad I saw this video!!!! Thank you for this. I just bought a pristine 2002 Dakota 4.7 Magnum. Had it 2 days and submerging myself with info. 👍👍
I bought an 2006 Dakota 4.7 magnum and I’m doing the same thing rn
SOLID VIDEO!!!! Please make more!
Crazy my 02 started acted up getting hot and leaking never knew there was so much into a simple fluid change I might have screwed it up on the fill up will redo the right way with new housing thanks brotha
Love your sense of humor awesome vid great info thanks man
My 4.7 was just overheating. Thermostat. Then, that didn't work, and had to do a water pump and full flush. Works great now. As a teenager, my first Jeep was a 4.2, then graduated to a 4.0. They were forgiving engines that allowed me to trial and error and learn. I now have a 3.7 and a 4.7 for dailies. I don't mess with them since they are much more picky and I just bring them to my Jeep guy. Probably cheaper too to have an expert do it once than me do it three times. There's value in learning, but not in Alaska in the winter haha
Useful, well delivery, good video learned alot thank you.
My daughter/son-in-law have a well taken care of 02 Columbia edition wj, when the time came for a new water pump, I chose one with an aluminum impeller and an aluminum thermostat housing for replacement, no PLASTICS. It runs perfectly.
I have an 02 wj limited and love the truck. Bought it 6 yrs ago at 101k has 146k on it now. Was leaving work a few weeks back and without warning or an overheat it lost a head gasket. Seats are still in the heads. Currently doing the gaskets on it now with a whole new rebuilt top end. It appears that the gasket at number 8 cylinder was the issue. The heads look great, no pitting or corrosion. The truck to me is worth putting the money into. It still looks great and before this treated me well. I will say this though, I have done heads on 4.6 fords in their passenger cars, I would take them over this job any day. There is no room at all in that engine bay.
I started working on the Jeep 2003 at 52000.and it's always something.
Good vid man!!
absolutely love the 4.7, "does everything I ask, but have to watch the cooling system" well said, my sentiments exactly.
I've had mine since 2017 and she just dropped a valve seat. I blew the radiator. I'm just tearing it apart today and wanted to check out a few videos.
My 4.7 has over 300,000 km on it. Starting to think that I ought to replace the timing gears and chain to prevent disaster. Love my '03 Dakota.
Thank you for the tips.
Three engines replaced in my 4.7 truck within a month of each other then the water pump went. That they did not bleed right thank you for the video I did it myself
I had a 03 ram 4.7 and I loved it... I got 190k out of it b4 I spun a crank bearing... they are extremely picky on the oils. Don't swap from one to another brand or synthetic to standard... they love to gunk up and come apart... I'm currently buying another one, knowing all I know now. I hope to see 300k.
Thx for that . I also have found they are tempermental .but still love the 4.7 . Its like a partner in a relationship for shore .!!!! If you neglect it it wont end well .
Great video! After watching this and reading some of the comments, I feel the need to chime in. I currently own 2 grand cherokees, 1WJ/4.0 4wd, and a 2007 WK w/4.7/4wd. I drove both of these when I was working and traveled on average around 36,000 miles per year. I bought the WJ with approximately 150,000 miles, while the WK had 167,000 miles. As of today, the WJ has 342,000 miles and the WK has 363,000 miles. I am anal about maintenance on both so I would hopefully avoid any downtime when I was working. I keep the WJ as a spare because it starts and runs, and everything works. The WK has been the best vehicle I’ve owned so far, and my wife drives it now and has for the last 3-1/2 years, as I graduated to a 2012 F-150 (with 283,000 miles). I’m living proof that proper maintenance on anything will make it last longer. Most of my repairs consist of replacing worn out parts. That 4.7 has been so good that I plan on replacing it if it ever fails! Not posting this to brag, but just wanted to let others know that the sky’s the limit on these if you maintain them properly. Again, a great video! Thanks!
Great vid bro, I think I'll just get rid of mine, had her for 8yrs with no big dramas but yeah I just want to step up to a 2010 srt8, they have issues to but they look so dam great lol
I was headed home with the wife and kids few days ago when my 4.7 upper radiator hose blew ended up having to use the good orange plus gas station coolant and to my delight the bright green stuff just to get home. I ended up flushing it like three times using radiator flush. Put in supercool and new coolant so far so good
Jeez.. what a mess! Glad you got her home anyway
Yea me too thanks to stores closing early i was lucky id gotten coolant for my 4.0 wj i had with me
I've got a 4.7 in my 00' Durango, I didn't know how temperamental the cooling system was and Im glad I found this video, I will be doing a drain and flush soon now that I do know. I haven't had any issues cooling wise but I do have a pretty bad exhaust leak which I've heard is fairly common, being that the studs on the manifold will snap or back themselves out, but I enjoy my Durango overall, and hope for many more miles, especially with it being my first and only car
yea bud VERY temperamental, but if you understand the things that make it different you will be fine. I have about 5 videos on the 4.7 cooling system. check them out if you have more questions
Did the exhaust leak sound like a tapping noise?
Thanks. And your not joking. I live in San Antonio.
@@jcstevegigs I had a tapping noise on cold start until the engine warmed up with my 4.7. I thought it may be a bad lifter that would finally pump up when warm but my mechanic said it was just a bad exhaust gasket.
Thank you for this video man
Currently thinking about buying a wj with a 4.7. its already been replaced because it did 4.7 things. 😂 Price is good enough, glad i found these vids
Appreciate this video fur sure. I've been eyeballing a 4.7 Durango.
I got a 2000 WJ with the 4.7 230k plus on the odometer runs great doesn't burn oil,no leaks, no smoke on start up, no ticks, no knocks it's mint. In other words you do the basic maintenance it can be reliable
Dude, you are awesome.
Ill be giving you a shoutout on my next video. Thank you for being great!
I had no idea it took the orange fluid!!! 🤦🏼♀️ it’s had green as long as I have had it…..and I just flushed my entire cooling system and put green back in. That’s what was in it when I acquired it a few years back. EXCELLENT INFO!! Thank you for this video. Guess we will be doing another flush and go get some orange 😒 ugh 😑
It happens to SO many of these. somewhere in the past someone switched them to green and no one knows it isnt right
Thank you for the info on the power steering and yes your a funny guy from New Jersey’s:).? I want one of those shirts cool. I have a 06 commander both 5.8 and 4.7.
Running 2005 4.7 and haven't had many issues. Cooling is fine. Normal leaks around trans cooler lines. Just reached 250k miles. Timing chains getting changed this weekend. I'll be instalin new lifters as well. Should be a smooth repair.
Awesome video! Thank you so much!!!!
My 4.7 loves you. Finally gonna get the tlc she needs
Thank you for the great VIDEO!!
Hey man I have a 2001 Dodge Durango with a 4.7 high output motor the good motor it's a really good motor I have 210000 miles on the original owner of that vehicle fully loaded all perspective vehicle to tow a lot of weight and I still have a went ahead 206 thousand miles of Elsie's dropped without using the orange coolant I was using the green coolant from the factory you still got the valve seats
I have a 2002 ram 1500 with the 4.7 and I love the motor, a little weak for a truck but it’s usable still and sounds good. Mine has seemed to be an oddball compared to other peoples 4.7s. Mine for one I have overheated all the way pegged to the red zone on the gauge and never had an issue. My truck has 253k on it but the motor supposedly was replaced with a new one around 70k miles ago. But it has been a great engine for me. Always started even in -40 and run good. Don’t have the head gasket issue and has around 150-160 compression all around very good. This engine is absolutely dead reliable if you take care of it, keep it cool and give it fresh oil every 3k and it will last. Mine doesn’t even barely have the lifter tick, but it’s easy to get to and I’m paying attention so the first time I ever hear it I’ll do the lifters.
Also specifically about the cooling system on mine, you don’t have to bleed mine, rather, you can’t from the bleeder. I have a coolant reservoir that is integrated into the cooling system. It’s much higher than the bleeder port so coolant just pours out of there and when I started it, it geysered like crazy. All you have to do on mine is fill the coolant up in the tank and run it till it’s mostly warm and make sure it’s topped off and it’s just fine. Thai system was very weird and they only used it’s in 2002-2003 rams and then they changed it to a traditional style overflow tank that is literally just an overflow tank instead of a pressurized container that constantly has coolant flowing through it. I have done so much research and learning and experiments on this motor and have come to know a lot. Take care of it and it’s good.
Every cooling component in my 2002 GC 4.7 needed replaced at 130k. I bought it was 123k in 2015ish, and no I didn’t know the history of it’s maintenance - only that it was a 1-owner. In addition to burning 2 quarts of oil every 2500 miles and having the mysterious death wobble (lots of suspensions parts replaced but it never went away). I gave Jeep one last chance when I traded it in for a 2011 V6 with 65k, and that one has been very solid in terms of reliability. The first month I had this one, I replaced all fluids (transmission, diff, coolant, etc), got it aligned, put new tires, pads, rotors, SERP belt, spark plugs, filters etc on it. It not has 100k and hasn’t cost me a dime out of pocket other than the routine preventive maintenance (factory recommended stuff, although with more frequent servicing). I miss the feel of my V8 though. My next vehicle will likely be another GC, a 5.7L Grand Cherokee L. I feel like I can bypass the reliability issues by buying it while it’s still young and keeping it with the preventive maintenance like I do with my current one.
The original green stuff is just fine in fact as far as I’ve ever been able to tell 1999 and 2000 came with it. The problems start when you don’t keep it changed every couple years because the corrosion inhibitors get depleted.
Also 99 and 2000 with towing package got the water pump mounted in addition to the electric fan ... if one fails at least you have one still working.
Welp.. I'm about to get my first 4.7, after running my (Light-A 3.9) for 32 years.. its still running btw, like a champ... at half a million miles, its been over heated to the point of exploding the cap off the radiator and blowing lines clean off the engine, has never needed a re-build and still starts up year round and runs great without burning any oil or antifreeze. Absolutely in-destructible engine that you can not break no matter what you do wrong. SO... adding a 4.7L to the chrysler collection, now I'm glad I saw your videos because I will do the opposite of what I do with my 3.9L L.A. engine. lol I'll have to get the proper coolant, proper power steering fluid, maybe order up an electric fan kit and throw that contraption in the trash.. But thanks for the info. Also I run Signature Series AMSOIL in my half a million mile 3.9, I have no way of knowing whats in the 4.7L.... I just have to assume its probably synthetic, anyway am planning to do the same in both my dakotas 5w30 amsoil + napa brand WIX filters. seems like a good combo, has worked so far. Thanks for the video's. ANY MORE ADVICE is welcome though, my 4.7L truck is a 2005 Laramie, would like to make it last as its a nice fully optioned out truck.
Awesome! Congrats! Wish you the best of luck with it
I had a 2003 4.7 that ran great then had tons of electrical problems. Then I got a 2002 liberty with the 3.7 and it dropped a valve lmao. Said I’d never go back to Jeep’s but now I’m looking at another 4.7👀
Great Video
I’ve had my wj for almost 5yrs and have changed the therm housing and seal twice. Damn plastic housings warp from heat cycles i keep a spare on the shelf. Also have changed one water pump so far. Other than that and regular maintenance it’s been a good vehicle. i bought it with 80k miles it now has close to 150k.
I have had a 4.7 Dakota for 18 yrs. Did not about the need for orange coolant. Thanks for the heads up.
I appreciate that thursday dove there bud
My 4.7 Dakota engine has been dependable as heck for 12 years... I’ve done one service to the cooling system in the life of the truck. A full flush, thermostat, fresh coolant, and a new water pump, maybe 5 years ago... I put in a 185 degree thermostat since I heard these trucks don’t like to get hot. Then again I Never heard of a truck that likes to get hot... I am planning to upgrade the original mechanical fan clutch to a new heavy duty towing fan clutch...
Orange Julius is also my favorite Cool vid 👍
Great video with some great information. I gotta put the orange stuff in there asap I guess...
That information is good to know. Now I have to go through my 4.7 and rid myself of that fan. After I tackle my odd injector codes and running like a Ford issue. Any trouble with injectors yet? I noticed the wiring harness that comes around the passenger side is a horribly tight fit. Man I hope it's just a couple of wires. Thanks for sharing the video though. Helps out alot on what I need to look for on my Jeep.
I'm about to buy a Dakota with a 4.7 and a 6 speed. Loved the video! I run green coolant in everything I own because I learned while working at the dealership that ALL colors and makes of coolant is corrosive when oxygen is introduced into a closed system (e.g leaks) and gm Dexcool is the absolute worst. I like dodge orange or pink just fine but, when I change to the green(it doesn't break down as fast in my case) I completely flush the system at least twice and then I run the great only when I know for sure there is no color left in the block or radiator. Iv had the best luck with my green stuff, and the Mopar pinkish color (that o.a.t stuff). Both for me have never given a problem. I hope my Dakota will be reliable once I go through and catch up with stuff people always neglect
I got a durango 02. Ive fixed it, well im doing it right now for the 4th time. Replaced the motor, fixed that one, did it again 20000 miles ago. I have 365000 miles, original transmission, just replaced ac motor. Ive had it for 14 yrs and people ask why i keep fixing it. Simple. It always starts, never leaves me on the road. Ive towed why over limit and she still runs great. Its upbto me to keep it up, i do that, she will run forever. The 4.7 is temperamental but learn it and you will live it. I may never get rid of it. My 02 has always kept me going. Just learn your car and you will have very little problems. Thanks for the info. Ive been using wrong antifreeze..
Ive had good luck with the 4.7 in my WJ and I'm at 208000 miles definitely get the mech and electric combo fans though. keeps it cool even in super hot weather
Ive been looking into adding the electrical fan on mine since I swapped out the to the mech fan. Honestly I don't think I need an electrical fan because the mech fan keeps it cool with no issues. Even while towing.
@@chewbakka0911 what mechanical fan blade and clutch did you go with I'm thinking about upgrading to a dorman 620-155 fan blade and hayden 2794 fan clutch for my 2000 4.7L with tow package, when I bought the jeep it had the factory steel 5 blade and the electric fan relay was by-passed and the wiring burnt up.
@@richardseaman6221 ya-228 fan blade and clutch from a 97-01 mountaineer F67Z8A616NA
Tip to. I'd run a cycle of water through the cooling system flush all green out before putting in orange. Unless formulas have changed orange coolant reacts with green coolant causes a foaming then dries and corrodes entire system. Hats off to the assistant director she's doing a hell of a job!! Jeep jeeeep!!
