NOTE: It is recommended to replace your Radiator Fan Clutch & Water Pump at the same time. The two parts age at the same rate so if one has failed, the other is probably not far behind. The fan clutch and water pump are also connected by the same shaft. When one part fails it typically affects the operation of the other. To prevent premature failure of your new unit, it is wise to replace both at the same time.
