Oil cooler — removal and installation

On a vehicle with a diesel engine, the oil cooler is located between the oil filter and its base. The oil is cooled by the coolant passing through the oil cooler. The advantage of this arrangement of the oil cooler is the rapid heating of cold oil to operating temperature. The oil cooler can only be removed after removing the oil filter and disconnecting the hoses. To do this, unscrew the nut located on its lower surface.



The oil cooler is sealed on the base of the filter with an O-ring (pic. 457). The tightening torque of the nut is 25 Nm.
