Installation Notes and Tips

Verify belt routing, rib count, and measured length against the original belt before installation. Inspect pulleys, tensioners, and idlers for wear or misalignment, since those conditions can shorten belt life. Confirm the vehicle’s alternator configuration where noted, especially on 1997-1998 Oldsmobile Silhouette and Pontiac Trans Sport applications with a 140A alternator.
