The engine oil cooler is located on the top of the cylinder block, between the cylinder heads. The cooler is sealed to the cylinder block with a gasket and secured with 18 screws.
There are 4 ports on the underside of the cooler:
- Engine oil - intake
- Engine oil - outlet
- Engine coolant - intake
- Engine coolant - outlet
The engine oil cooler is an aluminum housing comprising of fins and plates. The plates allow a cross-flow of engine oil and engine coolant through the cooler but keeping the 2 fluids separate.
The engine coolant is directed from the engine coolant pump into the oil cooler via a hose.
The plates are immersed in engine coolant supplied from the engine coolant pump. This provides cooling of the engine oil by a temperature differential between the engine oil and the engine coolant.
An anti-drain valve is located in the cylinder block and prevents the engine oil cooler draining when the engine is not running.
