What This Belt Helps Address

• Squealing or slipping from a worn accessory drive belt
• Cracking, glazing, or fraying on the existing serpentine belt
• Loss of proper drive to the air conditioning compressor
• Alternator drive issues caused by belt wear or incorrect length
• Poor belt tracking from an incorrect rib profile or section size

Installation Notes and Tips

Verify the belt section, rib count, effective length, and outside circumference against the original belt before installation. Inspect pulleys, tensioners, and idlers for wear or misalignment, since a new belt will not correct damaged accessory drive components. Confirm the vehicle application by position: BMW Z4, BMW M3, and BMW Z3 listings are for air conditioning, while the Jaguar XJS listing is for alternator service.
