Fig. 1: A gauge is recommended, but the belt deflection may be checked using light thumb pressure
Fig. 2: Loosening alternator pivot/adjustment bolt in order to tighten the belt Fig. 3: Apply tension to the belt being careful not to damage the case. While holding accessory in this position, tighten the pivot bolt.

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. REMOVAL & INSTALLATION V-Belt Fig. 1: Loosen the component mounting and adjusting bolts slightly
Fig. 2: Remove the belt by pushing the component toward the engine

To remove a V-style drive belt, simply loosen the accessory being driven and move it on its pivot point to free the belt. Then, remove the belt. It is important to note that on engines with many driven accessories, several or all of the belts may have to be removed to get at the one to be replaced.

A belt tensioner is used on these models, to maintain proper belt tension. To relieve belt tension, rotate the belt tensioner (using a 15mm socket) to relieve pressure on the belt. With tension relieved, the belt may then be removed from the engine. It is important to note the belt location at each pulley, to assure correct installation, and proper operation of the engine cooling system. A diagram may be helpful in denoting belt positioning. NOTE: Take care not to bend the tensioner when applying torque. Damage to i would like to get - prev.gifioner will occur. Maximum torque to load belt should not exceed 30 ft. lbs. (41 Nm).
