Ecodiesel Overheating Issue a Recall?

[wwtucson]

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

I switch to manual and down shift to get the same rpm's as if I re-geared where it over heats on hills. No difference. I've also used the Tazer to put the fan into high speed mode. No change.

@TimO

any chance we might get your response to the questions for you in this thread you started?

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).

No regear. Running 37's. I go to manual and down shift so RPM equal to regear 4.56. No help.

Maybe I wasn't clear. The original purpose of my post wasn't to revisit the the well established issue of the eco-diesel overheating and derating under what many consider normal driving conditions. I was simply wondering if anyone knows if this issue has been submitted and/or considered for a recall by either Stellantis or the National Highway Traffic Safety Administration.

answer to your original question; if there had been, we would have heard about it.

still trying to determine your idea of "normal driving conditions"; are you running stock size tires? if yes, did you regear to compensate?

“we would've heard about it’, not necessarily. If a potential recall was pending with the national safety transportation board, I doubt if we would have heard about it. I was thinking if one of the forum members had an inside track on any pending recalls regarding the ecodiesel’s overheating issue they could let us know.

The definition of normal driving is subjective. To me normal driving is any type of driving related to a jeep’s intended purpose (within reason) without having to fix, modify or repair in order to do so. For example, I should be able to drive from Sacramento to Lake Tahoe, pulling a small trailer less than 4000 pounds without the engine derating and having to drive slower than the flow of traffic or dangerously pulling over to the side of the road. I should not have to fix an engineering or design flaw from the factory. Particularly if it potentially results in a dangerous driving situation.

agreed; "normal driving" could be considered subjective.

that's why the question; does your include no tire size changes, with or without regearing?

Less than 4,000 pounds? Are you also over the (stupidly low) load limit?

I live in Sacramento area and drive over the sierras often. Sometimes towing a small trailer which is about 2k lbs dry, maybe 2.5k loaded normally. I just shift into manual mode while maintaining between 2.3-2.6k rpms on the tach while monitoring the oil temps. I seem to be able to maintain a minimum of 55-60 while towing through the steepest stretch and about 60-65 without the trailer doing that. Speed limit towing is 55 regardless. Trick is to downshift earlier than you would think.

Like I've wrote about a dozen times...the Jeep Eco Diesel is amazing and pulls like a locomotive, get stupid good fuel mileage but...it gets HOT when it starts to blow boost. The intercooler is in front of the radiator and the small engine bay is not any help at all.

All that heat from the intercooler, which on any other application, is designed to be dumped elsewhere just keeps building up...fact of life.

I have an early build 2020, absolutely love it but have learned how to mitigate the issue...

1.) Don't boost and never work the turbo more than 15 psi. (Ya, that will work but what's the point...LOL)

This is where I get serious...

2.) Get the Z-automotive TAZER JL. The ONLY feature of any use is the fan control and the restart defeat. If you are in a situation where it's gonna heat up, RUN THE FAN...period...RUN THE FAN.
2a.) If the ambient is in the 30°f's or 40°f's it's not a huge problem, get any higher, watch it.

3.) Get the larger mor efficient aluminum radiator. It only helps marginally, but is a step in the right direction.

3.) Cut out the hood vents and make them functional, again, marginal...

4.) Get the Green Diesel tune with the 190°f thermostat. HUGE improvement when used with the fan control.

5.) Get a RAM 3500 with the Cummins...(insert humor here).

I presently have 70k miles on mine and have pulled a 5k GeoPro trailer for probably 30k of that, ya, 30,000 miles. East of the Rockies I never had ANY issues but once ya get out west, watch out.

It's just the way it is with this rig. If you aren't up to the challenge just dump it and get something that fit's your needs better.

JMHO

1.) Don't boost

A turbo without boost. An interesting concept.

...That was a bit of humor, sorry

Thanks, everyone. My original post was simply to ask if anyone knew of any pending recalls related to heating issues with the EcoDiesel. I didn't intend to open up a discussion on how to diagnose or fix overheating problems—I already have a pretty good handle on that.

That said, I truly appreciate everyone who took the time to offer suggestions and share their experience. It's clear this is a group that genuinely wants to help, and I appreciate all of the input. Thanks again, everyone!
