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.
