Inspect the belts for signs of glazing or cracking. A glazed belt will be perfectly smooth from slippage, while a good belt will have a slight texture of fabric visible. Cracks will usually start at the inner edge of the belt and run outward. All worn or damaged drive belts should be replaced immediately. It is best to replace all drive belts at one time, as a preventive maintenance measure, during this service operation.
See Figures 6, 7, 8 and 9
Belts are normally adjusted by loosening the bolts of the accessory being driven and moving that accessory on its pivot points until the proper tension is applied to the belt. The accessory is held in this position while the bolts are tightened. To determine proper belt tension, you can purchase a belt tension gauge or simply use the deflection method. To determine deflection, press inward on the belt at the mid-point of its longest straight run. The belt should deflect (move inward) 3 / 8 - 1 / 2 in. (10-13mm). A general rule for alternator belt tension is that the pulley should not be capable of being turned with hand pressure.Serpentine Belt
On most newer vehicles, a single belt is used to drive all of the engine accessories formerly driven by multiple V-belts. The single belt is referred to as a serpentine belt. All the belt driven accessories are rigidly mounted with belt tension maintained by a spring loaded tensioner. Because of the belt tensioner, no adjustment is necessary.
