BMW N54/N55 Accessory Belt Service Kits
Your BMW's generator, fans, water pumps and AC compressors all rely on accessory drive belts to do their job. Over time, cracking, glazing, and squeaking occur; for these reasons, replacing your drive belts before they crack or break is a highly prudent investment.
Additionally, If the accessory belt snaps constantly, or is sloppy and loose in your vehicle, the only solution is a new tensioner.
The ECS-assembled kit comes with everything you need to refresh your whole drive belt system, including belts, tensioner, and hardware.
