The engine oil cooler is located on the top of the cylinder block, in the 'V' between the cylinder heads. The cooler is sealed to the cylinder block with a gasket and secured with 18 screws.
There are four ports on the underside of the cooler:
- Engine oil inlet
- Engine oil outlet
- Engine coolant inlet
- Engine coolant outlet.
The engine oil cooler is an aluminum housing comprising louvered fins and plates. The plates allow a cross-flow of engine oil and engine coolant through the cooler but keeping the two fluids separate.
The engine coolant is directed from the engine coolant pump into the cooler via a hose.
The plates are immersed in engine coolant from the engine coolant pump which provides cooling of the engine oil by the 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 of oil when the engine is not running.
