Your engine is equipped with a serpentine belt that drives the alternator. For maximum engine performance and maximum utilization of your engine, inspect the belt for wear and for cracking. Replace the belt, if necessary.

To replace the belt, insert a ratchet with a square drive into the square hole that is located in belt tensioner (1). Rotate the belt tensioner counterclockwise in order to relieve tension on the belt. Remove the belt.

Install the new belt correctly, as shown. Be sure that the belt is fully seated on the pulleys. The correct tension will automatically be applied when the ratchet is removed.
