P012F code for oil cooler

2010 F350 in my shop today. so, before dismantling the entire top of the motor for this inbred oil cooler job, is there anything else responsible for the P012 engine oil temp issue? it throws the wrench icon and cuts power and i pulled the P012F code.
thanks!!

Thermostats on those engines are notorious for failure too. The replacements are updated, but the ones I've replaced have usually set a P00B7 in continuous memory, which will also put the engine into reduced power mode and throw the wrench light, just as well as P012F. Have you monitored your ECT and EOT temps?

If it can monitor engine coolant temperature, there isn't reason why it shouldn't be able to monitor engine oil temperature too.

but if stat was bad it would overheat coolant. this code i believe indicates engine oil temp has risen to within 15 degrees of coolant temp. ill monitor coolant temp but i think oil temp is the problem...

Are you the owner of the truck, or the one doing the work? Either way, as you can clearly see, it is a major undertaking. Not a cheap repair by any means.

My friends truck. He has a tractor/farm shop, experienced mechanic. I just diagnosed for him since he is not internet savvy.
i am an ex caterpillar mechanic and have a shop as well, but he is retired and can handle it easily.
