What is this repair?
Plain-English overview
The belt tensioner keeps the serpentine or accessory belt at the correct tension; a failing tensioner causes belt slip, noise or sudden belt loss. Idler pulleys guide the belt path and fail similarly.

How to tell your JEEP needs this repair
- Squealing or chirping from the belt, especially when cold or under electrical load
- Visible wobble or roughness in the tensioner or idler pulley when the engine runs
- Belt wearing faster than expected or running off-centre
- Rattling from the front of the engine at idle
- Battery, power steering or overheating warning (if belt has slipped completely)
