3. Reinstall the water pump pulley. Be sure to tighten the bolts properly.14. Reinstall the water pump belt and any other belts that were attached to the water pump pulley.
For rear-wheel or all-wheel drive cars, remove the fan from the water pump pulley assembly. Removing the radiator and fan shroud are recommended, and probably necessary in order to continue.
4. After removing any nearby obstructions, loosen any belt tensioners and remove the belt(s) from the water pump pulley.
5. Remove the water pump pulley. The water pump pulley is responsible for driving the water pump, but has to be removed in order to access the pump. There are typically several bolts holding the pulley in place. Remove any bolts and save them for reassembly.
