The deep oil pan is only for the 2014 - 2019 EcoDiesel. I have one on my 2015, which now is a 12-quart capacity.

Yep, saw that … would love one for the JL/JT … what kind of temp reduction did you see with it ? I’d imagine 5-10 degrees… when in motion of course.

It's really hard to know, but I would guess a good 8*F reduction on the longer grades. The extra capacity gives the oil more time to rest and cool before it's cycled back through the engine. Essentially, the oil takes longer for the temps to reach overheat protection.

The 2014 - 2019 EcoDiesel has cooling issues due to the radiator/intercooler stacked design. As long as I slow down, then I can avoid derate on any of the long steep mountain passes in the Mountain West.

Took my jeep to the dealer for oil change, fuel filter blah blah blah, but I mentioned the hot temps and aerate towing a 4000lb airstream . They said they needed my trailer and drive up the hill I noticed the aerate to further diagnose … I told them to escalate because this issue needs to be addressed. Somehow.

perhaps they did fix it by removing the ecodiesel :-/ …

but I’m not going to leave my truck and airstream at the dealer and let them drive up to the mountains to replicate the derate… ridiculous. And they were serious too…
JEEP knows this was and would be an issue before the 1st diesel Jeep.was built, yet they still built it, sold it and gave it an unrealistic tow rating. Anyone who says they tow and never debated is a liar. They all will do this as oil temps rise automatically by the PCM to protect the engine. Any dealer that wants to recreate this is ignorant and has untrained and uninformed techs. Now I have a JT that just went over 100,000 miles and has been at dealer 5 weeks now after breaking down twice after the DPF wad replaced just 150 miles earlier and now claimed has to be replaced again which would make the 4th DPF in 50K miles. All of my diesel and trans related issues have been blamed by my towing of a 2600lb trailer coast to coast twice a year. Most common breakdown failure to regen but 2 turbos replaced, trans replaced at 50K, now 4 DPFs since 50K and exhaust replaced once. It's been in the shop more than a dozen times for more than a.total of 140 days, most breakdowns 1000 miles or more from home and every dealer tells me the same thing....it's due to towing and the diesel in the Wrangler type vehicles is more than a problem than it was worth to try to sell more vehicles when they would have still sold the same number of JTs with or without the diesel option. I've also been told that All Gladiators have a higher instance of warranty repairs of any Jeep model and that 2026 will be the final year of production due to lower sales numbers that go down year after year and to make room for the new midsized Ram truck that was designed from the ground up. RIP Gladiators will be the phrase sooner than later as consumers have seemingly abandoned the Jeep truck fir many reasons.

Why haven’t you dumped it yet?

I’ve just accepted mine will never tow anything like a 1/2 or 3/4 ton and am planing to move on from this truck that I’ve while heartedly loved for 3 years.

I have nearly 50K in adds but am now pursuing a federal lemon law action against Jeep which won't require a buy back but will result in a cash settlement

Generally speaking, I encourage people who plan to do a lot of towing to stay within 70% of the maximum rated capacity to ensure a positive towing experience. The 3rd gen EcoDiesel in the Jeep is unique in that the maximum tow rating is limited by cooling rather than the axle, suspension, chassis, etc. It was the same way in the 2014 - 2019 Ram trucks. The Hemi had a higher tow rating than the EcoDiesel simply due to cooling restrictions.

Staying within that 70% capacity is more of a guideline than a rule, but it does give truck buyers a good starting point when choosing trucks and trim levels. For example, my 2023 Rubicon EcoDiesel is rated for 6,000 lbs of towing capacity. If I were to follow the 70% guideline, then I would want to keep my towing loads at 4,200 lbs or under.

I don't want to pick on @steelponycowboy too much, but he claims to only be towing 2,600 lbs. But if you look at his Rubicon, he's running a lift kit with taller (heavier) tires. Both of those deviations from the factory specification are not ideal for towing and running cooler temperatures. He also has some type of camper shell/rooftop apparatus in his profile picture that will further add additional strain to the engine. It would be interesting to know what his payload is when towing.

Good luck…. My understanding is their financial position is currently rejecting all buy backs, period, a cash settlement isn’t looking much better….

Stock price isn’t the lowest it’s ever been, but uhhh, yeah ;)

So your logic is that because your experience has been shitty, everyone else who hasn’t experienced the same (regardless of different circumstances, use cases, etc.) must be liars?🤔 In other words, 1+1=3 and if you disagree then 🤬 you.

From everything you described you got a lemon. Sucks for you and I would be pissed off too, but that fact doesn’t make them all lemons. Best of luck on your settlement but spare us all the illogical, bombastic BS, you just sound more and more like a crazy person or glitching bot…

Hi my name is RudeJeepin and I'm a LIAR. I tow roughly 4k pounds with my JTRD and have never had a derate. Never ever, not here in the PNW with the JTRD, or when I towed 2k with my JLURD to Moab and back pushing 60 to 70mph most of the time.
Yep, I'm a Liar.🤣


Sorry, couldn't help myself.

I tow 3-4 times a year a very loaded 16ft enclosed trailer from the northern border to the southern tip of texas and I have never derated. My JTRD also is running heavy 38s. I'm just not an idiot and when I see temps start to rise I slow down and I don't use cruise control while towing. Either you got a lemon or you just don't know how to drive. Either way your bitching is quite annoying.

No wish I didn't have to bitch but after owning 36 trouble free Jeeps prior to the Gladiator I do what I can to warn people about buying one based on not only my experiences but those of others documented on this forum. Ive had lots of fun when it runs as one would expect but plenty of heartbreak when it sits at a dealer broke down again and again for the same chit problems. Jeeps failed experiment into a pick up version is coming to an end. in no more being built after 2026 so enjoy while you can.

Well financially speaking Stellantis is hurting which is why they've denied 3 warranty claims that should have been covered. Dealer said they have been rejecting lots of warranty claims because the vehicle was used for off reading WTF

See, that’s the logic I had , so I bought a trailer 66% in my maximum … and it doesn’t perform 😡

It should perform fairly well at 66%. Is your issue overheating (reaching derate)?

Yea, derate up the grades here in AZ. Power is lovely, cooling sucks. 95-100 degrees, AC and small airstream (aerodynamic).

I can’t imagine those EGR coolers (there are 2) help the situation much, if you see where I’m going.

I don’t know if it’s this thread , but I’d like to;
Stage 2 tune
4.56 gears
Auxiliary cooler
And a splash of water wetter.

I’d expect those changes to buy some good margin.

apparently there are aftermarket radiators trickling the market, but in my experience with TJ/LJs is just a gamble in terms of performance or reliability… example, I put a champion radiator in an old LJ that ran hotter than stock but lasted years! And I recently put a cold case radiator in my current LJ that cooled impressively but it leaks at less than a year old.

I’m also considering a bypass oil filter and add a small oil cooler inline.

bottom line, I want this jeep to last and do what it’s built for without slowly dying every time I use it.
