Oil Temperature High
 

All,

I have an 05 4.8is and never saw the oil temperature going slightly higher than the middle (210 F), but last week it was right between 210 and 300 F , in the past even if oil temp went up the coolant temp always stayed in the middle, however this time that went higher too.

I went home and added some coolant as it seemed low, since then i have been reluctant to drive the X5 for longer distances, is there anything i can check to see whats could have caused this? at the time I was parked with AC on and engine running.

Thanks for your help

check fan operations and expansion tank fill levels

Thank You StephenVA

I did add more coolant, however not sure about fan operation, is this an Aux Fan? I do not have any Fan in front of the radiator, please let me know.

Thanks for your help.

Since the coolant temp is normal, the oil temp is most likely normal which suggests the problem is the oil temp sending unit. With a laser temp reader you can check the coolant temp at the expansion tank and the oil at the pan.

+1 on the test do not guess approach!
