The oil cooler is located on the side of the cylinder block, below the intake manifold. The oil cooler is sealed to the cylinder block with a metal gasket and secured with 7 bolts.
The engine oil inlet and outlet connections are located on the inner side of the oil cooler. The coolant inlet and outlet connections are located on the outer side of the oil cooler.
The oil cooler is an aluminum housing comprising louvered fins and plates. The plates allow a cross-flow of oil and engine coolant through the cooler but keep the 2 fluids separate. The plates are immersed in engine coolant from the variable coolant pump. The variable coolant pump cools the oil with the temperature differential between the oil and the engine coolant.
An anti-drain valve is located in the engine oil inlet connection, which prevents the oil draining from the oil cooler when the engine is not running.
