About this part

This ACDelco Professional kit is for the air conditioning belt drive. It includes a serpentine belt, idler or idlers, tensioner or tensioners and supporting hardware, with detailed instructions. ACDelco's approach is to replace the belt, idlers and tensioners together to cut down on repeat repairs, since worn pulleys quickly damage a new belt. ACDelco describes it as a premium aftermarket replacement made for fit, form and function.
