First, find a diagram of the correct routing around the pulleys for your car. There may be one on a sticker under the hood somewhere; if not you may find one online, or just draw a diagram of the old one before you remove it. On a serpentine belt system, there is one pulley that tensions the belt. Relieve the tension on this pulley, and remove the old belt. Install the new one, carefully following your diagram. Make sure that you get the grooved side of the belt on the ribs of the ribbed pulleys correctly; you don't want it over the edge of the pulley.
