Question Oil temps cooler than coolant temps

Okay anyone got some insight in temps. How can I be running cooler oil than my coolant? I'll double check the temps but oil temps reading 155* when coolant is 185*-190*.

Any ideas?

If you are still running the EGR cooler your exhaust is heating the coolant.....

Modded EGR up-pipe so the exhaust is bypassing the OEM EGR cooler. Good thinking though.

Water pump problems perhaps.

Mine was doing the same thing......the more I drove the cooler my oil got, my coolant stayed normal.

I replaced the eot sensor and it solved the problem....for like 35$.

I think I'm using the wrong PID with the scan gauge.

I would think water pump possibly aswell. Grab that bottom radiator hose and it should be hot, if not, thats a good sign of a water pump failure.

It's an AreoForce gauge, not the Scan Gauge.
