When is the best time to change the oil cooler in 06/ 6.0?
I'm also having issues with higher oil temps and I see you also have a GoGo stage I intake...I'd suggest another "fix" before doing the whole replacement. I have recently replaced my oil cooler and still have the EOT/ECT split.
I know now there is an oil cooler bypass plunger/valve/whatever at the bottom of the oil filter housing. I will be replacing this small $9+ (from the dealer) part hoping this is the solution to my issue. Since this plunger would cause the oil to NOT flow into the cooler when activated or stuck I think this is a cheap investment versus doing another replacement (in my case).
I'll post up my results when completed.
