What It Helps Address

• Loss of alternator drive performance from belt slip
• Air conditioning drive issues on supported Honda Odyssey applications
• Incorrect belt length or rib count during replacement service

Installation Notes and Tips

Verify the belt routing, rib count, and measured length before installation. Confirm the vehicle application by year, make, model, and accessory position, especially on BMW 330i, BMW 430i, Audi SQ5, and Honda Odyssey listings where the belt position is specified. Inspect pulleys, tensioners, and idlers for wear before installing the new belt, and replace any damaged components that could affect belt tracking.
