Description

Oil Cooler Thermostat – the thermostatic control valve in the engine oil cooling circuit.

It regulates oil flow to the oil cooler in response to oil temperature, restricting flow through the cooler while the oil is still cold and opening progressively to route oil through the cooler once it reaches operating temperature. This keeps the lubricant within its target temperature band and prevents over-cooling during warm-up.

Fitted at the oil cooler take-off on both four-cylinder and V8 applications equipped with an engine oil cooler.
