The oil cooler absorbs heat, which is vital for engine cooling. Oil cooling uses engine oil as a coolant to remove excessive heat from internal combustion engines. Keeping engine components at their normal working temperatures improves performance and extends service life.

Function Of an Engine Oil Cooler

The oil cooler’s job is to maintain the oil at the proper operating temperature, which is between 230- and 260-degrees Fahrenheit. They are heat exchangers, which act similarly to a car’s radiator. The purpose of their large surface area is to radiate as much heat as possible to the surrounding air or coolant, depending on the kind of oil cooler.
