Installation Notes and Tips

Verify belt routing against the vehicle’s underhood diagram before installation. Confirm the application by year, make, model, and engine accessory layout, especially on vehicles noted for original drive design requirements or solution kit recommendations, such as select Toyota Corolla, Toyota Matrix, Toyota Celica, and Volkswagen Passat applications. Check pulley condition, tensioner operation, and alignment before installing the new belt to help prevent premature wear.
