Description
An oil cooler is a device that might not be common knowledge for most people, but it is a part that, if it goes bad, can seriously damage your car. An oil cooler is a separate, smaller radiator from an engine's main radiator, which maintains an oil supply at a consistent, optimal temperature. Essentially, oil that is cool prolongs the life of your engine or transmission.
Engine and transmission failures start to occur when oil cannot dissipate its collected heat fast enough and rises past this threshold. As it begins to break down, oil loses its lubricating, as well as its cooling properties.
