Oil Cooler

Find New OEM engine oil coolers for GM vehicles. Our factory-original oil cooler assemblies are sourced from GM surplus — the correct core flow rate, pressure drop, and mounting configuration for your specific engine.

The engine oil cooler maintains oil temperature within the operating range that protects bearing surfaces and maintains oil viscosity under sustained high-load conditions. An OEM cooler provides the factory-specified thermal management capacity for your engine — ensuring oil temperature stability during towing, track use, or hot weather operation.

Verify oil cooler specifications against your engine's cooling system configuration before ordering. Oil cooler replacement requires proper coolant system bleeding after installation.
