| 2 | Engine coolant inlet from cylinder block |
| 3 | Outlet - Engine oil |
| 4 | Inlet - Engine oil |
The engine oil cooler is located on the side of the cylinder block, below the turbocharger. The oil cooler is sealed to the cylinder block with a metal gasket and secured with 7 bolts.
There are 3 ports on the underside of the cooler:
- An engine oil inlet
- An engine oil outlet
- An engine coolant inlet.
There is a port on the other side of the oil cooler for an 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 keep the 2 fluids separate. The plates are immersed in engine coolant from the variable coolant pump. The variable coolant pump 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 oil draining from the engine oil cooler when the engine is not running.
