Structure
The heat exchanger (oil-water) (2) consists of multiple plates (P) in which the engine oil circulates.
Function
As from an engine oil temperature of 115 °C, when the oil thermostat closes the bypass to the oil filter, the engine oil is guided through the heat exchanger (oil-water) (2). Coolant circulates around the heat exchanger (oil-water) (2), thereby cooling the engine oil.
