There's an idler wheel in the surpentine belt circuit along with the AC compressor, the main crank pully and the alternator. The purpose is to keep tension on the belt, and this idler is spring-loaded. If no serpentine belt diagram is available create one before beginning the steps below. In the center of the idler is a 15mm bolt head. Place a closed-end wrench on this bolt head with the free end pointed towards the front of the vehicle and pry the idler in an upwards motion. Hold the ider in the "up" position and slip the serpentine belt off of the alternator pully with the other hand. Release tension on the wrench slowly and allow the idler to lower to it's bottom stop.

AnswerThere are three bolts involved. The top bolt located closest to the engine is your Pivot bolt. Loosen that bolt so the alternator will pivot downward when you unlock it. Speaking of unlocking, there is another bolt located on the bottom of the alternator, loosen and remove this bolt. Finally, on the front of the alternator there is a tension adjustment bolt. Loosen that until the belt clears the pulley so that you can remove it. You don't have to remove the tension bolt, just loosen it. Once the belt is removed make sure to disconnect any wire/plugs, etc from the alternator, remove the pivot bolt and viola! Installation is the reversal.
