Oil Coolers

Oil Coolers

An oil cooler’s primary function is to cool the engine lubricating oil, which in turn lowers the temperature of critical engine components, primarily the engine bearings. When oil exceeds normal operating temperatures, it loses viscosity and lubricating properties; when this happens, the oil begins to break down and deteriorate very quickly. Oil coolers extend the life of the engine oil and the longevity of your engine. Oil coolers should always be replaced after a catastrophic engine failure or when rebuilding an engine.
