What It Helps Address

• Worn or damaged water pump pulley surfaces
• Belt tracking issues caused by pulley wear
• Noise from a rough or out-of-round pulley
• Accessory belt slip related to rib mismatch

Installation Notes and Tips

Verify pulley dimensions, rib count, and belt routing before installation. Inspect the accessory belt, tensioner, and adjacent pulleys for wear at the same time, since a damaged belt system can shorten the service life of the replacement pulley. Confirm vehicle application by year and model before ordering.
