The Volkswagen Passat uses an electric fan to help cool the engine's radiator. The fan mounts between the radiator and engine block. The most common reason for replacing a radiator fan in a Passat is a burnt-out fan motor. Due to constant heat from the engine, and the close proximity of the fan motor to the engine, the motor eventually overheats and stops working. Experienced home mechanics can replace the fan in a few simple steps.
Remove the bolts that secure the upper radiator shroud to the radiator support cross beam on the top front of the engine using a socket and ratchet. Set the radiator shroud off to the side.
Unplug the wiring harness from the back of the radiator fan motor.
Remove the four bolts that secure the radiator fan shroud to the radiator supports. There is one bolt in each corner of the shroud.
Pull the radiator fan shroud upward to remove the shroud and fan as one unit.
Slide the new radiator fan shroud and fan between the radiator and engine block.
Secure the fan shroud to the radiator supports using the four bolts, socket and ratchet.
Plug the wiring harness into the fan motor.
Place the radiator shroud on top of the radiator and secure it using the bolts, socket and ratchet.
