Diesel cooling options and ideas

[Tortuga41]

Five 2" holes will have almost no impact on the integrity of a bumper made of 3/16" steel, especially that between the press-brake bend where the lower section is adding strength and the winch plate above the holes. The frame will already be bending by the time enough force is put on that to deform it.

All well and good and creative on your part BUT you've not only compromised the strength of the bumper but also voided any warranty on it at the same time. I appreciate Bulletproof Diesel coming up with the fix which I brought to their attention as a problem early in 2021 when they went over my JT taking pics and measurements then buying their own diesel to experiment on. I was not able to take advantage of their findings and had to pass being the first JT with their.cooler as I have an aftermarket bumper with a 12K winch.. I was not willing to mount a winch above to restrict the already deficient cooling system so I passed. Since then I realized what Jeep already knew and why they stopped selling it, the 3.0 is a total.POS. with now looks like 130 days total in the shop with now over $50k in warranty repairs ALL diesel related. I have written documentation from 2 dealers stating the issues that Jeep knows about but has kept from the public and will soon be seeing them under the Federal Lemon Law. Warning once you have a warranty claim on a part, they will do their best to deny future claims for BS reasons. I think a Class Action suit is in order for those of us that have had serious issues with our 3.0s, something my attorney suggested. End of story......

It is 1/4” aluminum, second hand off of FB marketplace. I added stainless steel reinforcements to the winch area, sandwiching the bumper. I am also not going to live in fear of warranty voiding. Just sharing info, not trying to convince anyone of anything. Sorry to hear your diesel experience hasn’t been great.

I've been told by more than one dealer it was a POS in the Jeep and by a mid manager at Stellantis that it never should have been put in a Jeep. The pump is a common Bosch pump that Jeep stalled and the Feds stepped in. I am on my 4th DPF now and it has cost Jeep.more to.fix all the issues than it cost them to build it. As for the Ram, it was a good motor in the Ram.as it had plenty of engine compartment to keep the engine.cool. .The lack of space in the Jeep and excessive heat is why it is problematic and not reliable in the Jeep.and now they are starting to deny warranty claims on multiple.failures of critical components/systems.which is why I have to sue. I've taken very good.care of, had dealers do.all.oil changes and required maintenance to preserve my warranty and this is how I am repaid. It's been in the shop now going on 3 weeks, all injectors were bad, DPF bad again after being replaced 3 weeks ago and now having to replace that again they have to replace a partial wiring harness and two sensors. Yes it's a POS

Did you dump your POS yet via the lemon law?

I’ve found limits with heat too… it might be time to just get a gasser or a full size pickup if you need to carry that much weight… curious if one of those excuses you received was related to the weight you’ve added?

The EcoDiesel in the Wrangler and Gladiator has some cooling issues, especially when pushed hard, but that's not going to be an issue for most owners.

The pump is a common Bosch pump that Jeep stalled and the Feds stepped in.

The feds didn't force Ram/Jeep to recall the pump. GM and Ford also used the CP4 pump. Ram did an internal investigation and found approximately a 1% failure rate.

I am on my 4th DPF now

You've got something wrong with your Jeep and your dealer hasn't diagnosed it correctly. DPFs fail when they are clogged with ash, which takes about 100,000 - 150,000 miles on the Gen 3 engine. You've got an issue somewhere else in the system that is causing your issues.

Sorry all that happened to you but your bad experience doesn’t mean all other 3.0D are lemons as well. I had a ‘20 Honda Odyssey that had 10 issues in 2 years but that doesn’t mean all other Odysseys were junk. Even Porsche had 911 GT3 engines blowing a few years back so they warrantied it for 10 years (sounds familiar with Stellantis warranty on the 3.0D) and that’s a $175k car. Lastly, Lexus/Toyota is having to replace all their new twin turbo engines in the LX600 (real Land Cruiser) due to manufacturing contaminant problems. We all expect perfection but rarely experience it. What makes this platform so great is the people that drive it. This forum is chock full of ideas and solutions to problems and durability issues…the wealth of information is astounding from actual users of these rigs. In the end I hope you obtain a favorable outcome and get what fits your needs and makes you happy to drive.

One of the excuses was towing. I regularly tow a 2500lb trailer. Blamed that on trans failure and DPF not regen.

Yes every car mfg had issues. The Gladiator and the diesel in particular has a greater instance of warranty issues than any other Jeep model. That with struggling sales that continue to drop year after year is on reason that 2026 will be its expected last year of production. Many diesel owners have issues, I'm not the Lone victim to Jeeps mistakes

NOT just my dealer but dealers all over the country. My usual breakdown is 1000 or more miles from home. 1st DPF issue at 8k miles. This last DPF filter lasted 150 miles and was told that the injectors failing ruined the DPF filter. They fail often enough that many parts departments stock this part.

I remember reading an interview with a Jeep engineer back in 2018. That was when we heard about the cooling limitations due to the narrow front opening of the grille. It was made known back then that the diesel would have a lower towing capacity than the gasoline engine for that reason.

At that time, I had already owned and operated our 2015 Ram EcoDiesel, so I understood some of the cooling limitations due to the radiator/intercooler stacked designed.

At the end of the day, every consumer needs to assess their needs/wants and buy accordingly. We love our 2015 and 2020 Ram EcoDiesels, and use them on a daily basis. Eventually we'll have to add a 3500 Ram Cummins to our arsenal simply because of the towing and payload limitations of the 1/2-ton truck.

I've always wanted a capable midsize truck, so when Jeep released the Gladiator with the diesel, I knew that would be the truck for me. And so far, the Gladiator EcoDiesel has met and exceeded all my expectations for a midsized truck. I remember back when the 2011 Dodge Dakota had a maximum towing capacity of 4,900 lbs.

I think the issue is that some consumers want midsize trucks to do what 1500 trucks do. This cycle of behavior doesn't stop there. I'm guilty of it, too. We want 1500 trucks to do what 2500 trucks do. Then we want 2500 trucks to do what 3500 trucks do. Then we want a 3500 truck to do what a 4500 truck does, etc.

How close or over are you on payload?

Where are you getting your information? 2026 is the expected last year of production? Do you realize that Stellantis (Jeep) revealed that the Gladiator in its current form will be built through 2028 in the UAW agreement?

Yeah, 1/4" aluminum is going to be about the same strength as 3/16" steel - or better, depending on the alloy. That bumper is plenty strong to have a couple speed holes cut in it.

How do you explain those who have run their jeep EcoDiesels over 100,000 miles without issues? You've got some serious issues for sure, but it sounds likes your dealer(s) have misdiagnose your issues from the very beginning.

Did you have a CP4 failure? If so, that would send shrapnel downstream and damage your injectors.

I just wanted a Gladiator nothing to tow or haul heavy loads. 6000lb tow rating and it struggles with 2500 on hills and mountains. However it's now spent over 140 days at dealers and is still in the shop as we speak going on 30 days waiting on parts that have a National back order and won't be available until.some time in Nov. It's been nothing but trouble since 8k miles. Jeep rep said it never should have been put in Wrangler vehicles. Ram ecos don't have the issue Jeeps have because if the huge engine compartment and larger radiators.

Plenty of people have issues, I'm not alone and no never had CP4 failure. Diagnosis from day one have been correct and every dealer that's worked on it say the eco in Jeeps is a POS
