Installation Notes and Tips

Verify the belt length, rib count, and cross section against the vehicle’s accessory drive routing before installation. Confirm whether the application is listed with notes such as W/Elec. P.S. or W/O A.C., since those configuration details affect belt selection. Inspect pulleys, tensioners, and idlers for wear before installing the new belt, and make sure the belt tracks correctly across all grooves after startup.
