What is the function of an idler pulley?

An idler pulley helps guide the serpentine belt and maintain proper tension on the accessory drive system. It ensures that components like the alternator, power steering pump, and air conditioning compressor receive consistent rotation.

Does this pulley come with any mounting hardware?

This Gates idler pulley is designed as a direct replacement for the original part. Typically, mounting hardware is not included and you would reuse the hardware from the original pulley during installation.

How do I know if I need to replace my idler pulley?

Signs of a failing idler pulley include squealing noises from the belt area, wobbling of the pulley itself, or excessive vibration. If you're replacing the serpentine belt, it's a good time to inspect the idler pulley for wear or damage.
