    Important: 

       • 3.8 Liter Engine: Ensure that the face of the pulley hub is flush with the end of the pump shaft before you apply a load to the pulley hub.
       • 5.7 Liter Engine: Ensure that the pulley hub shoulder bottoms out completely on the pulley shaft before you apply a load to the pulley hub.
       • Ensure that the pulley goes on snug when installing the pulley with the special tool. If the pulley installs onto the pump shaft too easily, it will not relay engine power to the pump and should be replaced.
