210 coolant temps? do you have a bullet proof oil cooler or anything like that? I don't see the factory cooler giving a 210/164 temp result unless it's crazy plugged, but normally that would cause the temp split to go the other way.

It's an upgraded oil cooler from ford

Is that not the same thing?

Not sure why your oil temp is so low. Might have a stuck thermostat

 

[Pwrcummins]

Wouldn't a stuck t-stat be low coolant temp?

So is 210 too high?

Normal operating temp is around 190* for both oil and coolant temps....210
Seems kinda high but oil at 164* is definitely wrong! May want to look at gettig a new oil sensor...they are cheap and easy to fix

210 is higher than normal but it could be reached under heavy load with high ambient temps. Your fan clutch should be locked and screaming at that point.
Also not sure why your oil temp is so low. Are these readings after you have driven the truck for a decent amount of time to allow it to warm up? Coolant temp will come up faster than oil.

you need to read the EOT and ECT after it sits all night then they should read within a few * something is up with yours

Ya after Iv been driving it reads about a 40* split. Coolants is hot because I just went to a mud bog and got deep in a mud pit. Radiator is clogged. I cleaned it now. As far as oil temp it's always been that low.

maybe a cut wire right at the fan shroud? this is semi common and they even sell a protection sleeve (Ford OEM ) or a bad fan clutch /connection issue
curious to see your deltas this AM

OK, so sounds like you thermostat is stuck open. Low side coolant temps would be around 180-185*F.

That being said oil temp should be no higher than 10-15*F higher than coolant temp under normal driving conditions. High engine load, pulling grades, ect will increase oil temp and not be an accurate test procedure.

For what its worth 210*F oil temp is in no way bad or going to hurt anything.

Max temps should be set around 230*F coolant temp and 250*F oil temp.

Sounds like a possible EOT sensor problem.

EOT and ECT first thing in the morning should be within a few degrees of eachother.
