Engine temp disparity

Has anyone looked at the differences in engine temps between Jeep and Dodge eco diesels? Look at this thread:
Towing temps. Ram needs to spec a larger radiator

And they are complaining? I think we need to take a good look at what is making ours run so much hotter.

Re: Engine temp disparity

Quoting " engine temps at 230". What does that mean coolant or oil? Unless you go into limp mode you are fine.
Diesels are designed to run hot and this isn't a SuperDuty or Cummings engine which both run cold in comparison.
FCA wants the engine and transmission to run hot for efficiency. Note that the Ram was towing a 7800 pound trailer too.
Oil temps below 270F are not an issue.

No where did this guy say he was in limp mode.
By the way 7660 is the typical max weight towing for a RAM 1500 Ecodiesel.

Re: Engine temp disparity

These small light diesels will run hot in warm weather and under towing load. I have a 2006 VM Motori 4 cyl CRD ( Jeep KJ) did the same thing...towed 4500 lb TT in 110 ' heat going up 6% grades at 65 mph and never got to limp mode but coolant got hot. Only thing I added was a tranny cooler for the 545RFE. So I expect "the same thing " with my 3.0 but scaled up a bit ( max 6500 lbs)...as we all know just slow down for a bit and temps drop very fast. Heck I am 62 and there is nothing wrong like driving like an old man!

The Ram 1500 Ecodiesel engine holds 10 quarts of oil and the Jeep GC Ecodiesels only hold 8 quarts. The difference is probably why they have the larger capacity more towing...just my 2cents
