Installation Notes

Verify pulley diameter, width, bearing bore, and belt contact surface before installation. Confirm the accessory drive belt routing and the exact mounting position on the vehicle, especially on lower alternator, water pump, power steering, and air conditioning applications. Inspect the belt, tensioner, and adjacent pulleys for wear during service so the replacement pulley is installed into a clean, aligned drive path.
