1991 Chevy S-10 belts

Need engine size to provide you with the correct belt diagram.

To install belt, slip the belt into position over the pulleys. Pivot the component to properly adjust the belt tension, then secure the fasteners. No belt adjustment is necessary as the tensioner adjusts by spring action. If a problem with the belt is suspected (it squeals often during operation or appears too loose), check the belt length scale on the tensioner. If outside the acceptable range, check for improper belt routing, belt damage or wear. Most multiple ribbed belts stretch very little. If you are still unsure, compare the belt to a new one at your local parts store. If the belt length is the same, the automatic tensioner may need to be replaced.
