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.

You must first loosen the alternator, do not remove it. remove the alternator tension screws top and loosen the bottom screws DO NOT REMOVE push the alternator toward engine, for the a/c belt you must loosen the belt tension pulley and move it. replace in reverse order

You have to loosen the tension on the belt by loosen the nut normally found on the pulley located by the motorblock, manifold or even by the alternator pulley it's self.

loosen the tension on the belt with the tension pulley, remove the belt then disconnect your wires from the alternator then take the 3-4 bolts, holding the alternator on, off. then do the opposite to put the new one back on

Loosen the alternator tensioner bolt. You will be able to slide the alternator either way to adjust the tension on the belt.
