Starting with the four bolts that hold the fan assembly to the flange on the water pump pulley; remove the assembly out of the radiator cowling and the engine compartment. In case this is too troublesome, remove the cowling on the sides of the radiator and raise it a bit so that it clears. The next step is to loosen up the four bolts connecting the fan with the drive clutch and take apart the two parts. To reassemble, attach the fan drive to the fan and attach the assembly to the flange on the water pump pulley.
