Installation Notes and Tips

Verify belt routing against the vehicle’s accessory drive diagram before installation. Confirm the rib count, effective length, and outside circumference match the original belt specification for the Ford Transit-150, Transit-250, Transit-350, or Transit-350 HD. Inspect pulleys, tensioners, and idlers for wear before installing the new belt, since damaged components can shorten belt life.
