What It Helps Address

• Overheating caused by pump wear or impeller damage
• Service issues on reverse-rotation accessory-belt cooling systems

Installation Notes and Tips

Verify reverse-rotation belt routing before installation. Inspect the mating surfaces, replace damaged gaskets, and confirm pulley alignment during assembly. Flush the cooling system if contamination or corrosion is present, and check belt condition while the pump is removed.
