I've had my fill on a 2016 RAM 3.6. Three replacements of the oil cooler and finally ended up buying factory. The owner brings it to me for oil changes as at least I know the filter torque specs. No metal Dorman units could be purchased at the time. Sold out.

Purging the air from the coolant is really important. FWIW, there was an air purge valve on the thermo housing that was hard to see and get to on the RAM as the engine is so far down into the engine bay. You would have to read or be told it was there to know.

This is actually my second oil filter housing failure on this jeep. First time I just had an oil leak and the dealer replaced with the OEM Mopar plastic filter housing.

I picked up a large funnel kit that attaches to the radiator in lieu of the cap that allows the coolant system to burp the air out of the system with heat on.
