About this part

Lube Oil Cooler
Oil Cooling Unit
Motor Oil Cooler
What this part does
The engine oil cooler regulates the operating temperature of the motor oil by routing it through a compact heat exchanger, transferring excess heat into the engine coolant circuit. It mounts directly to the engine block, typically integrating with the oil filter housing assembly. Maintaining oil temperature within a specific range is critical to preserve oil viscosity, prevent premature fluid breakdown, and protect internal engine bearings under heavy load. A failing cooler usually develops internal breaches that cause oil and coolant to mix, visible as a milky sludge in the reservoir, or external leaks at the mounting surfaces.

Before you order
You must replace the profile gaskets and O-rings that seal the oil cooler to the housing before installation; reusing compressed rubber seals will immediately cause pressure leaks. If you are replacing this unit due to an internal failure, perform a complete cooling system flush and change the engine oil and filter to eliminate any cross-contamination left behind by the old part.
