Filled up DEF from truck stop (my usual method - thinking it is more fresh) and on the way back to the campground we got a P207F Reductant Quality warning. Didn't have anything to swap the DEF in the truck - so we drove back to NC while the computer kept warning us X miles to limp mode. Back at home, used your method to swap the DEF and the warning cleared. Thanks again for the help. Now, I'll keep some transfer tubing in my truck just in case....and will start buying from the box with proper dates.
Yes I think the box is definitely the better way to go, just don't say that on any of the forums R you know how that will turn out, a big discussion. Haha
Very helpful video! I had a problem with the DEF gauge pegging empty when I overfilled the tank a bit using a DEF pump at a gas station. It also threw a check engine light - code P203B: an issue with the DEF level sensor circuit, but gave me none of the warnings about 5 mph mode or anything like that. After draining a gallon or so out, the gauge worked fine and the check engine light was able to be cleared. Before I did that, I stopped in at the dealer who told me I needed a new sensor and pump to the tune of > $2,000. I fixed it easily myself with the help from the video and the price of some tubing and primer bulb. Lesson learned and, needless to say, I won't be trusting that dealership with my business ever again.
Thanks for posting your comment. Mine through a code a few days ago as we set out on our long road trip. I checked the code with my scan tool and did some research and decided to roll the dice and go anyways, but I'm thinking I got the same problem you had. Maybe I overfilled it and it's misbehaving. I guess we'll see when we hit the road today.
Thanks for the video. It made the task simple. Do to Covid, I have hardly used my truck camper in the past year or more and the DEF was already old before then. It is gone and replaced now.
I recently purchased a 2016 Ram Laramie that I will be using to tow an Rv hopefully around North America in the future. I had no idea that my new truck took exhaust fluid. I thought since I owned a 1980’s VW Rabbit Diesel and a 1980’s Audi 5000 diesel I knew a bit about how they worked. Mind you both those vehicles were purchased overseas while serving my country and pickings were limited. Whats even more funny or clueless, depending on how you look at it, is fast forward almost 25 years and while working for Home Depot I would come across those boxes of DEF and I truly thought they were some sort of diesel cleaner or windshield cleaner. Anyways and needless to say I know very little about the workings of my new Ram Truck and I truly appreciate your videos about them. I will admit some of them seem a bit above my pay grade in terms of what you’re talking about but I truly appreciate your knowledge and the way you explain things. Thank you. ✌🏽🇺🇸🙏
Nice video, as are all of Marion's. Love his style and humor. My 2017 seems to use very little DEF when unloaded. Now have 15,000 miles, perhaps half of that towing 35' travel trailer. Have added 2.5 gallons of DEF 5 times. Nothing on dash indicates when a regeneration is in progress. Only way I know is that I can smell the super heated filter outside the truck. It would be nice to know when it's happening so I don't shut off the engine and interrupt the cycle. One would think that Chrysler would have a little light or something to say when it's happening. Dave
Thanks David, Yea, you'll never get an active regen when towing, exhaust gas temp is plenty high enough to burn the soot passively. Around town, maybe every 150 miles depending conditions etc.. thanks.
My 17' has just over 14k and i added my 5th 2.5 gal as you stated. Ive asked the dealer to add my feed back about an regen light for future trucks. I doubt that goes anywhere, but i said it anyway.
Get yourself an Edge CTS2 monitor and you can see everything going on with your truck. Later after the warranty is up you can upgrade it to a tuner if you want to. I run a stealth module on my 2018 ram 2500 and it really woke it up. Eliminates the turbo lag, really improves the throttle response, improves transmission shifting and holds gears better as well as improving fuel mileage. Absolutely worth every penny. I run it in the 90hp mode for unloaded everyday driving and the 60hp mode for towing. Completely safe and leaves no foot print because it does not flash the trucks stock tune as it plugs in downstream of the computer. I just unplug the stealth module and remove it before taking to the dealer and they are none the wiser.
@@hardtruth2039 Would you happen to have any more details about the stealth module running down stream of the computer? Links or more info on that and tuner or are they one in the same? Thank you.
Thanks for your many awesome videos, just discovered you a few days ago and going through them all. I have a 2017 Ram 3500 diesel and should have read the manual, too many things I should already know. Thanks so much!
Yea, I've slowed down a lot also so I thought it would be good insurance. It's pretty simple once you realize you can't get a siphon hose in the fill line, ha.
Another great video and knowledge transfer! Since I am in the warm south; I think I'll not keep the def tank full and let it run down a little past half before refilling. Thank you.
Thank your for this. I have had to replace my sensor at the dealership 2 times now, i am sure it is because i dont drive enough to use up my def before it goes bad. Just did this and got a bunch of white crystals out of the bottom of the tank. Hopefully this solves the problem. Probably nothing ever wrong with the sensor
Thanks for info on draining your tank. I think filling only 1/2 -2/3 way is best plan to prevent old def aging out in your truck. This product is used so slowly it probably ages & goes bad between fill ups. I am still confused on using box vs truck stop def pump. I think refill with good box with good dates might be best
I got a P1D54 code according to my FIXD code reader. Best I've been able to determine, it's an indication of the DEF being bad. Bought a specific gravity reader to check the DEF & it was out of specs. I will need to completely empty the DEF tank and refill. Will using a siphon hose completely empty the DEF tank or do you think it will make any difference if a small amount of the old fluid is left in the tank? Or is there a better way to completely empty the DEF tank? I greatly respect your opinion.
Thanks, I’m thinking of getting a diesel. I’m retired now and live in Texas. Your thoughts were mine too. Not a lot of use and that fluid would expire in the tank.
I took off the crossmember that the DEF tank rests on and pulled the tank out. I will tell you that it is not flat and does not have a low-point on the bottom, it's very bumpy/uneven. The only way I got it all out was to open the big round area where the pump is and then actually wipe it out. You'll never get close to removing it all with that bulb pump.
I like it, has much better throttle response and more positive shifting, no issues. so far. I just use a stock tune or a +30HP tow tune. I went with Double R Diesel, MM3 Tuner, 4" flo-pro downpipe-back exhaust with muffler. It makes a tiny bit of of smoke if I step on it, not bad though.
At start up, mine shows the >122 as well. 2017 2500 here. As soon as it goes to 123, I know the truck has warmed up (takes 10 minutes) and I go on my way
I usually add some when I’ve gone down between 1/4 and 1/2 a tank. And I would say I do that fairly regularly. I’ve had my truck since April 2017 and it’s got 40k miles on it already. I’m guessing with how regularly I have to add def, I shouldn’t have much to worry about, despite being in Texas.
Anyone have any issues with their Def gauge? Filled the tank almost 2 months ago to 100% and it hasn't budged. Watched "Motor City Mechanic's" explanation regarding the sonar system on the DEF pump/gauge. I am probably just being impatient and the fluid hasn't reached the upper sensing limits yet. Just curious if this is a common quirk.
I only put in a 2.5 gallon at a time. I let it get nearly empty. I'm adding about every two weeks now. Used to be once a month. New it was every two months.
i want a 2019 ram 2500 6.7l cummins, i don’t know much about diesel, how would this truck do as a daily driver/short trip truck, 6 miles to work and 6 miles back home? and can you do a manual regen on this truck?
Hi Khalil, I might have replied in another thread but, I think the DPF will handle the regens fine, With that much short trips, you'll want to change the oil more often. If you can get it up to operating temp daily, it should be fine.
Went in to dealer. Bad def injector, they had to order part. Truck has now gone into “count down” to derate. Fortunately I have a beater daily driver. I will let you know how replacement goes.
Was at dealer about 2hrs. They replaced injector, sometimes they go bad they said. Not reassuring or helpful. Haha. DEF was tested and within spec. Covered under warranty.
Do you know what all repairs are done when the dealer completes the "Clean EGR valve - crankcase filter"? I had it done at 68k miles and I now have a little over 120k miles on the truck. The procedure cost me just shy of $700.00 at my Dodge dealer and now that it is out of warranty, I was thinking about doing the next repair myself.
The CCV filter is about $70 and easy to change, Cleaning the EGR is not on the schedule but it's not difficult either. It's a little more involved than changing the CCV. $700 is way too much for doing just those two things. If they changed the diff fluids, transmission fluid, transfer case, engine oil, air cleaner etc... and did the EGR and CCV, that might be worth 700. The CCV doesn't need to be replaced till 135,000 and the EGR is not a maintenance item so you don't do anything to it unless you have a problem. Just the EGR and CCV will cost less than $100 if you do it yourself and is easy to do.
It'll clean itself when it's ready but if you are close to a regen, meaning the differential pressure across the filter is high enough for a regen to start, get out on a stretch of road and lug it a little, say like do 50 and accelerate a few times. Not flood boarding it or anything like that, actually better to stay in the same gear and try to lug/load it. Sometime you can fool it into thinking it's ready for a regen. Do everything at the same speed and check your mpg before you do the above, if you see your mpg drop by about 10 mpg, you've successfully got it into regen. But the short answer is, no, there is no way to manually cause a a regen. These systems are very well designed and you shouldn't have to do that but for fun you can try the above. Another way, if it's close, is get on the freeway and run at 70 or more and watch your mpg, before and after. It's hard to tell without a after market gauge. Some say they can smell it.
Marion Blair thanks for the info, I know on class 7/8 trucks you can do a manual regen by parking and flipping a switch to do it. I was considering buying either the ford 350 or dodge and I just like to be able to do it if necessary to clean the filter.
I totally agree, even a message on the dash or light would be nice to let you know an active regen available with some kind of switch to start it when you want. The big truck have it as you mentioned. The only time RAM gives a message on the EVIC is when the thing is 80% full which could get you in a lot of trouble if you are stuck in Houston traffic etc... My edge insight has a selection on it that allows will start a regen but it has been defeated by edge. Apparently for warranty reasons. I'm thinking there may be a monitor like this that will actually start a regen when you give the command. I'm going to look for that. The truck does a beautiful job of taking care of itself but you can cut off about 10 minutes of regen time if you are running at highway speeds since you are getting so much help from the passive exhaust temp being higher. It would be nice if you could take advantage of that knowing that you are getting ready to do some traffic driving, you could clean it out faster. thanks for the thoughts.
If they're going to use a system with liquids that won't last very long, they should put a drain plug on the tank. My Cummins 3500 truck needed a clutch and due to Covid, we had trouble finding one. By the time I got it back on the road, my DEF is apparently contaminated. About to go into limp mode in another 150 miles. I'll try to siphon it out. Thanks for the video. I just wonder if the computer will reset itself if I replace with new DEF. Does anyone know?
Marion, question for you: What is your opinion of these newer SCR emissions systems? I know the older systems (without SCR) had DPF and EGR issues and fuel efficiency suffered. Are the newer systems more reliable? Also, I've heard a lot of people say that you need to tow heavy with these newer diesels in order to keep the emissions systems functioning and clean? Is this true? I plan on buying a Ram 6.7l Cummins truck; I'll likely only tow occasionally, but I will be on the highway a lot (sometimes carrying heavy payloads for camping, hunting, wood clearing, ect.). Will that kind of usage be sufficient to keep the emissions systems happy. I know there are other diesel trucks (1/2 tons and midsized) which are perhaps better suited to my needs. I just really like the overkill nature of these 3/4 and 1 ton diesel trucks; it seems the big OEM's put a lot more effort into making them reliable and long-lasting.
Kal, I have a video on this exact subject, see below. But the short answer is no problem using it as a daily driver. There is a misconception that the diesel has to be loaded all the time or the EGR valve will clog up the system. In the old days, that was more or less true but the newer engines have closed EGR loop systems which run exhaust gas thru the system regardless or load or engine speed. So don't worry about that. If you drive mostly stop and go, the DPF will regenerate more (active regen) which uses diesel fuel to create oxidation to burn off soot in the DPF. On the highway, even empty, there's plenty enough heat so that passive regens will take care of the DPF soot. The system is really well designed. Once you own a 2500, you'll never go back to a 1500, I promise. It'll handle grocery get just fine just make your trips long enough for the oil temp to come up to full operating temp so any moisture etc.. can burn off. The egr/dpf system works in the background, so nothing really to worry about. ua-cam.com/video/dWscJr0VYQI/v-deo.html
Hoping this picture loads up but if not, what mine did was to initially start setting the reductant tank heater circuit high code. Then the dash gauge began reading empty although it was not. And of course the computer only knows what the tank unit is telling it. Which of course results in 5mph max when the mileage timer runs out. I drop the tank to find a white foamy layer in the bottom of it and the rubber parts on the pump,heater unit to be swollen. 900.00 later for the pump unit , wash out the tank and it's all good.
No there was what I would guess to be about 1/2 cup of a white somewhat thick layer of crud in there. I used hot water to wash it out and even had to use a few drops of dish soap on a rag to get a film off it that the hot water wouldn't dissolve.
If your trucks are still goin to dealers for repair i would be careful about deleteing the def/emmissions stuff...Im sure the dealer are working up to it as they are in effect with the big truck world but dealers will not work on it/void warranty and tell you to replace as it was before its touched..
@@MarionBlair I know for example that freightliner will tell you to replace ex and such in the same was it was built..So imagine you spend a small boatload to delete it all only to have dealer make you replace it then cost of repair on top of that..Expensive as hell..Actually a fella on youtube(dont remember his ch)was contact by epa and told to replace his pick ups ex n such to factory...Seems he had a epa viewer on his channel..
@@craig_sez8534 yeah that's a big reason why I probably won't delete because the EPA seems to be cracking down on this stuff. And I don't even want to think about having to reinstall that crap
It's only a problem if your truck doesn't get used much and you are in a very hot environment such as Las Vegas or the like. Within 6 months of installing a new tank of DEF you could have bad DEF which plugs the injector. Codes, Codes dealer visits, change injector, clean out tank etc... If you use your truck a lot and run a tank every few months, forget this video.
Someone’s UA-cam video confirms the facts presented here regarding Blue DEF and other brands. However, their video actually showed a container of Mopar DEF having an actual, straight-forward, imprinted date on the container with no whoopee cushion string of characters being necessary to decode!
Yes, I'm starting to see that also. The standard ISO/API is the whoopee cushion string however apparently some are deviating from that. I believe I saw a Walmart jug with a date on it also.
the Julian calendar is used by the Army for all maintenance records. it is used because it is unambiguous. Either you have to write out the date as DD Month YYYY, or you can end up with an ambiguous date because the Army uses DDMMYYYY while some use MMDDYYYY A Julian date is sometimes used to refer to a date format that is a combination of the current year and the number of days since the beginning of the year. For example, January 1, 2007 is represented as 2007001 and December 31, 2007 is represented as 2007365. Thus the Julian date is unambiguous.
All the time, it mixes with the NOX the engine produces and the two turns the exhaust into Nitrogen and Oxygen. By using the DEF, MPG increases 5% and also reduces NOX. (nitrogen oxide from combustion)
Like the video, but I fill at truck stop, they have and auto size nozzle and low fill pressure, then I put 2 gal, so mine stays fresh every 5 mths I add another 2 gal, and at 1/4 of the price a jug of money Walmart gets. I would worry about contamination of dirt going in the tank, I wouldn't ever do this
Why in the hell make the date code so complicated??? Why not just post month, day year......i.e. 05/23/2023. That would be soooo much simpler to use without needing a decoder ring!!
I've been watching a lot of these videos about the new diesels and I'm the kind of guy who doesn't want to get wrapped around the axle for lack of a better expression so the bottom line is I'm of the opinion now you don't buy a diesel unless you absolutely have got to because of towing or however you're going to use the truck. Cuz after watching all this bullshit I'm going to stick with a gas engine thank you very much LOL
@@MarionBlair just seems owning a Modern Diesel is actually maintenance intensive between additives and everything else I'm seeing in these videos. Everybody's bitching and moaning about something so I'm just saying stick with the gas engine and then just bitch and moan about only one thing... lack of fuel mileage LOL
Great video Marion! Thanks for taking the time to show us. I'm trying to siphon out DEF from my 2017 Ram 3500 right now. Did you siphon out a FULL DEF tank or was that tank partially full? I'm worried that DEF might come squirting out at me if I remove the fill line.
It's unlikely that will happen. It's got to be really full to do that though. I fill mine 100% in the Walmart parking lot in Texas and then drove home about 600 miles and drained it and it didn't overflow. So doubt that it's that full but keep a bucket underneath just in case, ha.
Ok people, seriously DEF is not going to cause any issues other than a few codes. Get an inexpensive code reader that allows you to delete the code if one pops up. Worst case scenario would be major scaling in the tank and at that point you would have to remove the tank and lines.
Marion Blair my 2017 Ram will be very similar. I have a company work truck so my RAM normally will just sit in the garage until summertime when we start camping and boating. During the winter months I will try at least a couple times every couple weeks to get it out on the highway and open her up. But I figure the DEF will be my only issue that I have due to not driving it. Still trying to figure out if it’s better to leave the tankful or about half full during the winter months.
I think I’ve read this on your channel before but does the engine exhaust system use a little bit of DEF all the time or is it just during regeneration?
Hot weather and def do not mix well, been there done that. The dosing system quit working one summer here in Vegas, right before the recall came out for the cats on the 14s, dealer made me pay for flushing the def....once a month make sure you put the truck through it's paces and burn some of that def off. Also, do yourself a favor and buy def from the diesel island at truck stops if you can. You know that stuff gets turned over frequently and it's roughly the same price as diesel instead of 7/8 dollars per gallon
Yea, As long as it's a full delete, just deleting the DEF will not fly on these trucks. It's the EGR that I'd like to see gone. DEF goes in downstream of the engine, it's not a big deal.
@@MarionBlair thanks sir so your saying 1000 mpg so I should get maximum 5000 miles out of a tank of def according to what your saying. If I understand what your saying my diesel brother.
Sell it private, with the delete it will be worth far more. Not to mention the better fuel mileage you will get. The bonus is no more DEF to buy. Have seen nothing but problems with this system. The company I work for bought one, it spent more time in the shop getting fixed because of DEF problems than it did working. In the winter it would fail ever time the temp went below -10 C, tail it into a warm shop, thaw it out and it would go out and fail again with in a hour.
I don't agree that it's worth more. Try selling a deleted truck privately in California and a lot of other states with similar laws. Not going to happen. Only a fool would buy a truck you can't register. Also, you come out better sometimes when you trade because you don't pay sales tax on the trade in. RAM says they will give me 41K for my 2014 as is. (totally stock Laramie, Paid 48K). That's $2870 and I don't have to deal with people coming to the house to test drive etc...
I guess being Canadian and not having to deal with those stupid EPA laws is the difference. Up here a deleted truck is worth 2to4 grand more. Infact having the DEF system actually makes them far less desirable. Same as any truck with the particulate filter system, with about half the price you can get without.
Disagree, Canada and US have the same EPA collaboration, I don't know how Canada does it but in the US, enforcement it's state by state. Some states, are more slack at enforcement, others like California, they mean business. I suspect all the states as well as Canada will gradually increase their enforcement. Canada is no different, you delete a truck with a warranty and you have no warranty. The only different is the trucks cost about 25% more in Canada due to exchange rates. So when you say, "just delete it", you need to consider the loses you could incur, the least being the cost of DEF which is next to nothing. Don't get me wrong, I'd love to "just delete it fool" as you put it and as I say i might at some point but it's not as simple as that unless you are willing to buy a new or used truck with no warranty. IMO, that would be the fool. My truck is over 4 years old and haven't had 1 single problem with DEF (but I did have to change out an entire rear axle under warranty). I don't know anything about -10 deg weather but I know there is a lot of RAMs running around Canada that's not deleted and doing fine. DEF system has a heater so I don't know what's going on with your company's truck but probably related.
TooTall's Vlog Yes, deleted my 2018 with 500 miles on her. Edge Insight CTS2, EGR & cooler delete, DEF delete, DPF delete, EFI live, S&B cold air intake, Banks monster intake & a 5" Flo Pro turbo back exhaust. No transmission tune needed cause I have a G56 transmission. Truck sounds like it's got a set of balls on it & I'm not destroying the engine with all the emissions bullshit.
I only put in a 2.5 gallon at a time. I let it get nearly empty. I'm adding about every two weeks now. Used to be once a month. New it was every two months.

Just did this and got a bunch of white crystals out of the bottom of the tank. Hopefully this solves the problem. Probably nothing ever wrong with the sensor
thanks EPA you are ruining engines
Thanks for info on draining your tank. I think filling only 1/2 -2/3 way is best plan to prevent old def aging out in your truck.

I got a P1D54 code according to my FIXD code reader. Best I've been able to determine, it's an indication of the DEF being bad. Bought a specific gravity reader to check the DEF & it was out of specs. I will need to completely empty the DEF tank and refill. Will using a siphon hose completely empty the DEF tank or do you think it will make any difference if a small amount of the old fluid is left in the tank? Or is there a better way to completely empty the DEF tank? I greatly respect your opinion.
Sir I really like your videos they are very informative thank you.
Thank you!
Thanks, I’m thinking of getting a diesel. I’m retired now and live in Texas. Your thoughts were mine too. Not a lot of use and that fluid would expire in the tank.
Also thank you as I always look to you for instructions they are much appreciated
Thanks
I have not looked at it yet. It’s going in for DEF service. P2048 code. I don’t drive it much so fluid sits. Need to think of ways to keep it fresh.
Yes same with me.
Great video as always. Thank You
Do you know something about to replace the external def pump on a ram 3500 Cummings 2011
I thought 2013 was the first year for DEF?
Oh man! I was at 1/2 a tank on def and decided to fill it prior to a trip to a week long trip to Arizona! 100 degree weather everyday 😭😭
Have u ever done a video regarding P020E???
No haven't, sorry.
I run through the DEF fluid so damn fast id never have to worry about dumping it
I took off the crossmember that the DEF tank rests on and pulled the tank out. I will tell you that it is not flat and does not have a low-point on the bottom, it's very bumpy/uneven. The only way I got it all out was to open the big round area where the pump is and then actually wipe it out. You'll never get close to removing it all with that bulb pump.
Thanks Christian, appreciate the info. I suspected I'd leave some behind. Why did you have to take the tank out?
You're welcome Marion. I didn't have to, but since I did a delete I didn't want it just sitting in there for years.
Yea, I'd do the same. How do you like the delete? What equip.../ tuner etc did you go with? Any transmission hard shift problem after delete.
I like it, has much better throttle response and more positive shifting, no issues. so far. I just use a stock tune or a +30HP tow tune. I went with Double R Diesel, MM3 Tuner, 4" flo-pro downpipe-back exhaust with muffler. It makes a tiny bit of of smoke if I step on it, not bad though.
Another great video. I notice that your 2014 shows oil temp even as low as the double digits. Mine just shows a
That's interesting, what year is your's?
At start up, mine shows the >122 as well. 2017 2500 here. As soon as it goes to 123, I know the truck has warmed up (takes 10 minutes) and I go on my way
I believe I over filled my def tank and worried about damage. Should I siphon some out?
No, won't hurt nothing. I've done it several times. There's a lot of unmeasured area in that tank.
I usually add some when I’ve gone down between 1/4 and 1/2 a tank. And I would say I do that fairly regularly. I’ve had my truck since April 2017 and it’s got 40k miles on it already. I’m guessing with how regularly I have to add def, I shouldn’t have much to worry about, despite being in Texas.
Nah. You're good. I've run a lot this summer and with winter on us, it'll be good into the summer.
Anyone have any issues with their Def gauge? Filled the tank almost 2 months ago to 100% and it hasn't budged. Watched "Motor City Mechanic's" explanation regarding the sonar system on the DEF pump/gauge. I am probably just being impatient and the fluid hasn't reached the upper sensing limits yet. Just curious if this is a common quirk.
Yes, they are all like that. The gauge is not linear. You can run it down to a half tank and add 2 1/2 gals and it will take it all.
Same issue, they just said I’d need to replace the def pump, $2,200, any suggestions?
I only put in a 2.5 gallon at a time. I let it get nearly empty. I'm adding about every two weeks now. Used to be once a month. New it was every two months.
Same here. Best thing to do imo.
i want a 2019 ram 2500 6.7l cummins, i don’t know much about diesel, how would this truck do as a daily driver/short trip truck, 6 miles to work and 6 miles back home? and can you do a manual regen on this truck?
Hi Khalil, I might have replied in another thread but, I think the DPF will handle the regens fine, With that much short trips, you'll want to change the oil more often. If you can get it up to operating temp daily, it should be fine.
Went in to dealer. Bad def injector, they had to order part. Truck has now gone into “count down” to derate. Fortunately I have a beater daily driver. I will let you know how replacement goes.
Yes, I'd like to follow up, thanks.
Was at dealer about 2hrs. They replaced injector, sometimes they go bad they said. Not reassuring or helpful. Haha. DEF was tested and within spec. Covered under warranty.
Good vid....better than some doofus telling you to rip off the emissions.
Lol why wouldn't you delete your truck?
Do you know what all repairs are done when the dealer completes the "Clean EGR valve - crankcase filter"? I had it done at 68k miles and I now have a little over 120k miles on the truck. The procedure cost me just shy of $700.00 at my Dodge dealer and now that it is out of warranty, I was thinking about doing the next repair myself.
The CCV filter is about $70 and easy to change, Cleaning the EGR is not on the schedule but it's not difficult either. It's a little more involved than changing the CCV. $700 is way too much for doing just those two things. If they changed the diff fluids, transmission fluid, transfer case, engine oil, air cleaner etc... and did the EGR and CCV, that might be worth 700. The CCV doesn't need to be replaced till 135,000 and the EGR is not a maintenance item so you don't do anything to it unless you have a problem. Just the EGR and CCV will cost less than $100 if you do it yourself and is easy to do.
I’m curious, Is there anyway to do a manual regen on the dodge rams? My father has one and I wanted to clean his dpf filter.
It'll clean itself when it's ready but if you are close to a regen, meaning the differential pressure across the filter is high enough for a regen to start, get out on a stretch of road and lug it a little, say like do 50 and accelerate a few times. Not flood boarding it or anything like that, actually better to stay in the same gear and try to lug/load it. Sometime you can fool it into thinking it's ready for a regen. Do everything at the same speed and check your mpg before you do the above, if you see your mpg drop by about 10 mpg, you've successfully got it into regen. But the short answer is, no, there is no way to manually cause a a regen. These systems are very well designed and you shouldn't have to do that but for fun you can try the above. Another way, if it's close, is get on the freeway and run at 70 or more and watch your mpg, before and after. It's hard to tell without a after market gauge. Some say they can smell it.
Marion Blair thanks for the info, I know on class 7/8 trucks you can do a manual regen by parking and flipping a switch to do it. I was considering buying either the ford 350 or dodge and I just like to be able to do it if necessary to clean the filter.
I totally agree, even a message on the dash or light would be nice to let you know an active regen available with some kind of switch to start it when you want. The big truck have it as you mentioned. The only time RAM gives a message on the EVIC is when the thing is 80% full which could get you in a lot of trouble if you are stuck in Houston traffic etc... My edge insight has a selection on it that allows will start a regen but it has been defeated by edge. Apparently for warranty reasons. I'm thinking there may be a monitor like this that will actually start a regen when you give the command. I'm going to look for that. The truck does a beautiful job of taking care of itself but you can cut off about 10 minutes of regen time if you are running at highway speeds since you are getting so much help from the passive exhaust temp being higher. It would be nice if you could take advantage of that knowing that you are getting ready to do some traffic driving, you could clean it out faster. thanks for the thoughts.
If the DEF is bad. It can mess up the DEF pump and DEF injector - what else can it damage?
That's about it. If NOX isn't in range, it'll start throwing codes.
If they're going to use a system with liquids that won't last very long, they should put a drain plug on the tank. My Cummins 3500 truck needed a clutch and due to Covid, we had trouble finding one. By the time I got it back on the road, my DEF is apparently contaminated. About to go into limp mode in another 150 miles. I'll try to siphon it out. Thanks for the video. I just wonder if the computer will reset itself if I replace with new DEF. Does anyone know?
Yea, computer don't care,
Marion, question for you:
What is your opinion of these newer SCR emissions systems? I know the older systems (without SCR) had DPF and EGR issues and fuel efficiency suffered. Are the newer systems more reliable?
Also, I've heard a lot of people say that you need to tow heavy with these newer diesels in order to keep the emissions systems functioning and clean? Is this true? I plan on buying a Ram 6.7l Cummins truck; I'll likely only tow occasionally, but I will be on the highway a lot (sometimes carrying heavy payloads for camping, hunting, wood clearing, ect.). Will that kind of usage be sufficient to keep the emissions systems happy.
I know there are other diesel trucks (1/2 tons and midsized) which are perhaps better suited to my needs. I just really like the overkill nature of these 3/4 and 1 ton diesel trucks; it seems the big OEM's put a lot more effort into making them reliable and long-lasting.
Kal, I have a video on this exact subject, see below. But the short answer is no problem using it as a daily driver. There is a misconception that the diesel has to be loaded all the time or the EGR valve will clog up the system. In the old days, that was more or less true but the newer engines have closed EGR loop systems which run exhaust gas thru the system regardless or load or engine speed. So don't worry about that. If you drive mostly stop and go, the DPF will regenerate more (active regen) which uses diesel fuel to create oxidation to burn off soot in the DPF. On the highway, even empty, there's plenty enough heat so that passive regens will take care of the DPF soot. The system is really well designed. Once you own a 2500, you'll never go back to a 1500, I promise. It'll handle grocery get just fine just make your trips long enough for the oil temp to come up to full operating temp so any moisture etc.. can burn off. The egr/dpf system works in the background, so nothing really to worry about.

Thanks. I'll check the video out. Your content is very helpful!
Hoping this picture loads up but if not, what mine did was to initially start setting the reductant tank heater circuit high code. Then the dash gauge began reading empty although it was not. And of course the computer only knows what the tank unit is telling it. Which of course results in 5mph max when the mileage timer runs out. I drop the tank to find a white foamy layer in the bottom of it and the rubber parts on the pump,heater unit to be swollen.
900.00 later for the pump unit , wash out the tank and it's all good.
Good Lord! $900
Yup, and I get my parts wholesale at the dealer. Otherwise it was 1100 something. At least it's an easy job though
@@redstagriding295 that's painful. How did the tank look? Clean?
No there was what I would guess to be about 1/2 cup of a white somewhat thick layer of crud in there. I used hot water to wash it out and even had to use a few drops of dish soap on a rag to get a film off it that the hot water wouldn't dissolve.
I have a picture but apparently cant upload it here
The number to check production is called a lot code
If your trucks are still goin to dealers for repair i would be careful about deleteing the def/emmissions stuff...Im sure the dealer are working up to it as they are in effect with the big truck world but dealers will not work on it/void warranty and tell you to replace as it was before its touched..
Yeah that's true for the powertrain for sure.
@@MarionBlair I know for example that freightliner will tell you to replace ex and such in the same was it was built..So imagine you spend a small boatload to delete it all only to have dealer make you replace it then cost of repair on top of that..Expensive as hell..Actually a fella on youtube(dont remember his ch)was contact by epa and told to replace his pick ups ex n such to factory...Seems he had a epa viewer on his channel..
@@craig_sez8534 yeah that's a big reason why I probably won't delete because the EPA seems to be cracking down on this stuff. And I don't even want to think about having to reinstall that crap
This is a problem? My truck gulps def down!
It's only a problem if your truck doesn't get used much and you are in a very hot environment such as Las Vegas or the like. Within 6 months of installing a new tank of DEF you could have bad DEF which plugs the injector. Codes, Codes dealer visits, change injector, clean out tank etc... If you use your truck a lot and run a tank every few months, forget this video.
Someone’s UA-cam video confirms the facts presented here regarding Blue DEF and other brands. However, their video actually showed a container of Mopar DEF having an actual, straight-forward, imprinted date on the container with no whoopee cushion string of characters being necessary to decode!
Yes, I'm starting to see that also. The standard ISO/API is the whoopee cushion string however apparently some are deviating from that. I believe I saw a Walmart jug with a date on it also.
Good tips before removing def tank thanks :)
How many times a year do you change your def
If it's more than a year old and I haven't used it then I try to change it
We need to question WHY “THEY NEED TO DATE CODE WAY
Because over time the urea in the fluid def crystallizes and plugs the injector in the exhaust and plugs the SCR catalytic converter.
I will let you know what they come up with. Next Friday.
I live in lower ny and it gets f#@%&mg HOT here in the summer too
the Julian calendar is used by the Army for all maintenance records. it is used because it is unambiguous. Either you have to write out the date as DD Month YYYY, or you can end up with an ambiguous date because the Army uses DDMMYYYY while some use MMDDYYYY
A Julian date is sometimes used to refer to a date format that is a combination of the current year and the number of days since the beginning of the year. For example, January 1, 2007 is represented as 2007001 and December 31, 2007 is represented as 2007365.
Thus the Julian date is unambiguous.
Does the DEF squirt in the system continuously every time the engines running or just when the screen is clogged to a certain point?
All the time, it mixes with the NOX the engine produces and the two turns the exhaust into Nitrogen and Oxygen. By using the DEF, MPG increases 5% and also reduces NOX. (nitrogen oxide from combustion)
Thanks Marion I wasn't that sure about it.
@@MarionBlair so you are saying that keeping the Def increase your MPG?
My understanding was the opposite.
100% the time engine is running
Good information 👍🏻
Great video as always sir. Much appreciated!
Like the video, but I fill at truck stop, they have and auto size nozzle and low fill pressure, then I put 2 gal, so mine stays fresh every 5 mths I add another 2 gal, and at 1/4 of the price a jug of money Walmart gets. I would worry about contamination of dirt going in the tank, I wouldn't ever do this
Thanks for the info....now I want to go check dates...lol
Why in the hell make the date code so complicated??? Why not just post month, day year......i.e. 05/23/2023. That would be soooo much simpler to use without needing a decoder ring!!
I've been watching a lot of these videos about the new diesels and I'm the kind of guy who doesn't want to get wrapped around the axle for lack of a better expression so the bottom line is I'm of the opinion now you don't buy a diesel unless you absolutely have got to because of towing or however you're going to use the truck. Cuz after watching all this bullshit I'm going to stick with a gas engine thank you very much LOL
I've always been a diesel lover so I would probably own one even if I didn't tow just listen to that baby purr. And the fuel mileage doesn't hurt.
@@MarionBlair just seems owning a Modern Diesel is actually maintenance intensive between additives and everything else I'm seeing in these videos. Everybody's bitching and moaning about something so I'm just saying stick with the gas engine and then just bitch and moan about only one thing... lack of fuel mileage LOL
Very good info Marion, thanks.
Great video Marion! Thanks for taking the time to show us. I'm trying to siphon out DEF from my 2017 Ram 3500 right now. Did you siphon out a FULL DEF tank or was that tank partially full? I'm worried that DEF might come squirting out at me if I remove the fill line.
It's unlikely that will happen. It's got to be really full to do that though. I fill mine 100% in the Walmart parking lot in Texas and then drove home about 600 miles and drained it and it didn't overflow. So doubt that it's that full but keep a bucket underneath just in case, ha.
Urea is basically cat piss. Notice the cat checking it out. lol
Ok. No wonder he took off. lol
Andrew Mackle maybe bring a cow with you then you don't have to worry about a use by date ! LoL 😅
I wonder how my wife would feel having a pet cow instead of that little dog.
Only one way to find out. Just make sure its house broken!
Ha, maybe I'll stick with the cat piss.
Nice job.. Great tip.. tks
Marion: What do you do with the old DEF after it has been removed?
Kevin Kunkle pour it down the drain it's harmless. Just don't drink it
Marion, I have the same question. What do I do with my used def? Can we really just pour it down the drain?
Pour on the grass it will make grass greener
I'm confused. I think you said in the video to just keep topping the DEF off instead of draining out all of it first?
Doesn't matter if you use a lot.
Thank you sir. You make great videos
Ok people, seriously DEF is not going to cause any issues other than a few codes. Get an inexpensive code reader that allows you to delete the code if one pops up. Worst case scenario would be major scaling in the tank and at that point you would have to remove the tank and lines.
Marion: I’m sorry if I overlooked the answer to this but how often are you going to perform the service?
I don't understand your question, what service are you talking about Gump?
I’m sorry: Draining & refilling the DEF tank.
Oh sorry, Only when my truck doesn't get much usage. If I can't add a 2 1/2 gal. DEF can every 6 months, I'm thinking I'll do it again.
Marion Blair my 2017 Ram will be very similar. I have a company work truck so my RAM normally will just sit in the garage until summertime when we start camping and boating. During the winter months I will try at least a couple times every couple weeks to get it out on the highway and open her up. But I figure the DEF will be my only issue that I have due to not driving it. Still trying to figure out if it’s better to leave the tankful or about half full during the winter months.
I think I’ve read this on your channel before but does the engine exhaust system use a little bit of DEF all the time or is it just during regeneration?
Great video,
Hot weather and def do not mix well, been there done that. The dosing system quit working one summer here in Vegas, right before the recall came out for the cats on the 14s, dealer made me pay for flushing the def....once a month make sure you put the truck through it's paces and burn some of that def off. Also, do yourself a favor and buy def from the diesel island at truck stops if you can. You know that stuff gets turned over frequently and it's roughly the same price as diesel instead of 7/8 dollars per gallon
Thanks for your input..
Why not just put a F-ing "Best By Date" on the bottle? This damn calculus deciphering system is ridiculous.
Yeah that's too screwed up for simpleton like me just put the freaking use by date
North it can freeze and break the plastic pumps
Hey man, dumb question. What are you removing the def fluid?
It has a shelf life. If you have it in higher temps, you'll have DEF problems if it goes bad.
Marion Blair did not know that. Thanks!
Def delete is the solution.
Yea, As long as it's a full delete, just deleting the DEF will not fly on these trucks. It's the EGR that I'd like to see gone. DEF goes in downstream of the engine, it's not a big deal.
Amen
Sitting in the sun has nothing to do with it. The def tank is always in the shade. Ambient temp is the only factor here.
Thank you!!!
Uses little that’s hilarious mine is a daily driver never tow and I can’t keep def in it!
should use 1000 MPG +-
@@MarionBlair thanks sir so your saying 1000 mpg so I should get maximum 5000 miles out of a tank of def according to what your saying. If I understand what your saying my diesel brother.
don’t use peak blue def. it’s complete shit cause of its high corrosion content.
Tell me about it. Just had to completely replace my tank. $2200.00. Ain't happy!
I use a full tank about every 3k miles.
Great info. Thanks.
Def delete it buddy let the truck breathe i deleted mines no regrets and also gets you from worrying about if the liquid is good 😂
Along with DPF/ EGR
Why can’t they use normal dates!! 😒
Yea, I don't get it either.
DEF FLUID
Diesel Exhaust Fluid Fluid.
Thank you, I also say DPF filter. I failed the 8th grade.
@@MarionBlair ATM Machine... automated teller machine machine
Yeah I do the same thing with DPF filter
Why not just run distilled water? A dealer wants $400 to drain that tank.
It'll throw a code and put you in limp mode
@@MarionBlair that’s why you delete it.
Why not just delete the whole DEF system and be done with it fool? That’s a far better idea
That may be in the cards at some point but deleting it rules out a trade in so for now I'm ok.
Sell it private, with the delete it will be worth far more. Not to mention the better fuel mileage you will get. The bonus is no more DEF to buy. Have seen nothing but problems with this system. The company I work for bought one, it spent more time in the shop getting fixed because of DEF problems than it did working. In the winter it would fail ever time the temp went below -10 C, tail it into a warm shop, thaw it out and it would go out and fail again with in a hour.
I don't agree that it's worth more. Try selling a deleted truck privately in California and a lot of other states with similar laws. Not going to happen. Only a fool would buy a truck you can't register. Also, you come out better sometimes when you trade because you don't pay sales tax on the trade in. RAM says they will give me 41K for my 2014 as is. (totally stock Laramie, Paid 48K). That's $2870 and I don't have to deal with people coming to the house to test drive etc...
I guess being Canadian and not having to deal with those stupid EPA laws is the difference. Up here a deleted truck is worth 2to4 grand more. Infact having the DEF system actually makes them far less desirable. Same as any truck with the particulate filter system, with about half the price you can get without.
Disagree, Canada and US have the same EPA collaboration, I don't know how Canada does it but in the US, enforcement it's state by state. Some states, are more slack at enforcement, others like California, they mean business. I suspect all the states as well as Canada will gradually increase their enforcement. Canada is no different, you delete a truck with a warranty and you have no warranty. The only different is the trucks cost about 25% more in Canada due to exchange rates. So when you say, "just delete it", you need to consider the loses you could incur, the least being the cost of DEF which is next to nothing. Don't get me wrong, I'd love to "just delete it fool" as you put it and as I say i might at some point but it's not as simple as that unless you are willing to buy a new or used truck with no warranty. IMO, that would be the fool. My truck is over 4 years old and haven't had 1 single problem with DEF (but I did have to change out an entire rear axle under warranty). I don't know anything about -10 deg weather but I know there is a lot of RAMs running around Canada that's not deleted and doing fine. DEF system has a heater so I don't know what's going on with your company's truck but probably related.
One more reason why Im not buying anymore diesel trucks.
They are certainly more complicated than they used to be. If you need the torque you got to put up with that crap.
Or delete the emissions crap & enjoy your diesel truck
Did you delete? If so, what system did you go with to reprogram the ECM? And did you include a transmission tune?
TooTall's Vlog Yes, deleted my 2018 with 500 miles on her. Edge Insight CTS2, EGR & cooler delete, DEF delete, DPF delete, EFI live, S&B cold air intake, Banks monster intake & a 5" Flo Pro turbo back exhaust. No transmission tune needed cause I have a G56 transmission. Truck sounds like it's got a set of balls on it & I'm not destroying the engine with all the emissions bullshit.
Greg Chamberlain just don't buy a newer diesel truck, buy one that's pre 2007.
Def means diesel exhaust fluid. You don't need to say def fluid.
What did I say?
Lol you delete the entire system
Yeah that's the solution
Then not be able to get an inspection within the next 18-24 months. No Thanks!!!!!!!!
@@pauldelesbore2788 yeah I know that's true in California and probably the fear of other states coming to us
When you spent all your money on the truck and now you don’t have money to go places you replace the DEF fluid
Do the same thing with a diesel
If that's one's situation, I wouldn't buy one. It's not mine.
Very helpful. Thanks for sharing
I only put in a 2.5 gallon at a time. I let it get nearly empty. I'm adding about every two weeks now. Used to be once a month. New it was every two months.
