IMPORTANT INFORMATION

Always confirm the correct OEM part number, engine model, and pulley configuration before ordering, as auxiliary belt dimensions and profiles may vary depending on engine specification and accessory layout. Incorrect belt selection or tension can result in charging faults, belt slip, premature wear, overheating, or loss of auxiliary system operation. Industry repair discussions also commonly identify pulley alignment and tensioner condition as important factors in auxiliary belt reliability and service life.
