What does an idler pulley do on my Jeep Wrangler?

An idler pulley on your 2.8L diesel engine helps maintain proper tension on the accessory drive belt. It also guides the belt along its path, ensuring it runs smoothly and doesn't slip or wear out prematurely.

How do I know if my idler pulley needs replacing?

Common signs of a failing idler pulley include squealing noises from the front of the engine, especially on startup or when turning the steering wheel. You might also notice excessive belt wobble or uneven belt wear.

Does this pulley come with any hardware for installation?

This Omix idler pulley is sold individually and is designed as a direct replacement for the original part. Installation hardware is typically not included, so you may need to reuse your existing hardware or source it separately.
