What is the main function of an idler pulley?

An idler pulley's primary job is to guide the serpentine belt and maintain proper tension. It helps ensure the belt makes full contact with the other pulleys it drives, like the alternator and power steering pump, for efficient operation.

How do I know if my idler pulley needs replacing?

Common signs of a failing idler pulley include squealing or chirping noises from the belt area, especially on startup or when turning the steering wheel. You might also notice excessive belt vibration or premature belt wear.

Does this pulley come with a new belt?

This product is for the idler belt drive pulley only. A new serpentine belt is not included and should be inspected separately for wear and replaced if necessary.

This idler belt drive pulley from Gates is designed to keep your serpentine belt running true, maintaining proper tension and alignment for all the components it drives, like the alternator, power steering pump, and air conditioning compressor.
