This may have been asked before, but I can't find it. It seems to me with all the overheating issues with the Ecodiesel, whether you’re driving in hot weather going up a grade, or towing in hot weather and in most cases towing less than the maximum rated total capacity, this overheating issue should be a recall. If a vehicle overheats under normal driving conditions, and in my opinion, towing or simply driving up a grade in hot weather is a normal driving condition in many parts of this country, the engineering of the vehicle is defective. Does anyone know if this issue has ever been considered for a recall to fix the issue?

I haven't seen many issues with overheating being reported and I haven't had any.

Maybe its a sensor or something. I have one and it got warm enough pulling a trailer to start glitching telling me I’m out of def. Deleting makes them run much cooler.

My 2023 3.0L over heats just looking at a hills. I've added a coolant radiator up front and dual oil bypass filters that add 3 qts of oil to my system. 72 degrees outside going at fwy speeds on flat road and oil temperature reads 225F.

Trying to cool exhaust gasses was a pretty dumb idea with such a small rad area . Like i say deleting makes a huge difference .

Wait what.... your the first I've ever seen mention this... sources, links, receipts ? Been following Wrangler/Gladiator forum since 2021, own a Diesel... never had a problem, never heard of anyone with an issue.
Please elaborate

You did all that? I live in Texas and when my oil cooler failed, the dealer fixed it. lasted 16 miles before I overheated for the first time. They fixed it and I Rin 230 degrees at 75 mph. no more overheating so far. Dealer want to replace all my coolant hoses and quoted me $4k, Told them I would replace them myself.

Its defiantly the Achilles heel of these rigs. I've only been able to "mitigate" the problem, and we'll never see any relief from MoPar. I've done just about everything there things all get in line, it's going to get hot but I NEVER let it derate.

Mine actually is pretty good...BUT, I've got a bigger aftermarket radiator, manual fan control from Z-Automotive and a tune from Green Diesel (amazing!!) with the 190°f thermostat. Between the T-stat and the fan control, it's...pretty OK...
The problem with a turbocharged diesel in a Wrangler is, there is no place for the intercooler except in front of the radiator...thus, turbo heat is directed right into the radiator that is suppose to remove friggn heat.
Rigs with more frontal area move the intercooler somewhere, anywhere away from in front of the radiator.
FYI, I work the shirt out'a this rig and also pull a 18' off road camp trailer.
Get the fan control, het the tune with the 190°f thermostat and you'll be 80% goo to go. It'll never be 100%, but "YOU DON'T ALWAYS GET WHAT YOU WANT.." as the song says...

Where did you get the 190 thermostat?
I'm in CA can't do a tune with smog laws.
3 extra qts of oil did help some with two bypass filters( Amsoil + Insame Diesel).

Green Diesel Engineering, but you gotta have their tune so it won't throw codes. It's an OEM thermostat but from Europe (where they don't try to kill diesels)
Look them up. Worth every penny!

having never had this problem, i have to ask; can you be more specific? what do you consider "overheating" ?
is it derating?
are you seeing coolant spew out?
or are you just not liking the temps you're seeing reported?

i've repeatedly run mine through 8000'+ desert mountains in triple-digit weather @ 80MPH and never had an issue. did it run warmer? of course; but it never failed to function in any way.

running moderately heavy with 37s and a RTT i'd expect that i'm pushing enough load that if i was going to have a problem i'd have had it already, but have to wonder if regearing (4.56s) is helping me avoid whatever issue there might be.
are you running stock size tires? if yes, did you regear to compensate?

i do believe the airflow through the cooling stack is less-than-adequate and did add a ventilated hood a year or so ago which may have made a *tiny* bit of difference at low speeds, but sadly didn't seem to make hardly any difference at speed (if any at all).

My oil temperature will hit 245 and coolant temperature will be around 12 degrees lower. That's when it goes into limp mode. Going up a hill running 37's with stock gears 3.71. I've tried manual down shifts to keep rpm up to 2,500 range. No help.
I haven't tried a big hill after adding two bypass filters that 3 extra qts of oil.

You might have already answered this... but did it overheat, prior to the bypasses and the three extra courts of oil ?

Yes. No extra cooling/filters first time oil temp hit 245.. Low 90's going South on I-5 going up the grape vines at 70mph. Took it into dealer, they replaced turbo and EGR. Still happened so I added the filters and extra coolant radiator in wench spot.
