To disassemble, remove the pump drive pulley. Unscrew the bolts securing the pump cover and remove it complete with the sleeve, shaft and impeller, disconnect the cover from the gasket plane with light blows of a plastic hammer. Unscrew the thermostat fitting and remove the thermostat with the sealing collar.
