Over time, accessory belts begin to wear out and crack. This can lead to the belt slipping, squeaking, or even snapping. Replace your belts and tensioners on a regular basis to ensure you don't end up stranded on the side of the road with a dead battery or overheated engine due to a bit of simple overlooked maintenance. This kit includes all of the items that will need to be replaced such as the belts, tensioners, and hardware.
