Description

Thermostat Housing for the 2.5L 300TDi 4-cylinder turbo diesel engine.

This housing secures the engine thermostat within the cooling circuit and forms the junction between the engine coolant outlet, the upper radiator hose connection, and the bypass circuit. A cracked or leaking housing will cause coolant loss and disrupted thermostat operation. Replacement of the housing gasket and thermostat is recommended when refitting.
