When you're replacing the accessory drive belt on your Audi S5, or perhaps a range of other vehicles like the Audi A6 or Volkswagen Touareg, making sure the idler pulley is in good shape is key. This Gates idler pulley is designed to keep your accessory belt running smoothly, which means your alternator, power steering pump, and A/C compressor can all do their jobs without issue.

Gates is a well-known name in belts and related components, and this pulley is built to handle the constant rotation and tension that comes with driving your car's accessories. It's made with durable materials to resist wear and tear, ensuring it won't seize up or start making noise prematurely.
