Before you start working on the oil cooler, raise the car on a hoist and drain out the coolant. After that, remove the oil cooler's coolant hoses, remove the
Oil Filter and then get rid of the oil cooler connector bolt. Go ahead and take out the oil cooler when you are finished. It is important to realize that cleaning the oil cooler is forbidden; when either rebuilding or replacing the engine, the cooler should also be replaced.
