Installation Notes and Tips

Verify the 5/8" diameter shaft requirement before ordering for Ford F-100, F-250, and F-350 applications. Confirm pulley requirements separately, since this pump is supplied without a pulley. Clean the mounting surface thoroughly before installation and use the included gaskets to help achieve a proper seal. Always inspect hoses, thermostat condition, and coolant quality when replacing a water pump.
