Most likely you have a serpentine belt, one continuous belt that drives the alternator, Power Steering, air conditioner compressor and there shoudl be one more pulley. It is usually the smallest pulley, it is called an idler pulley. It is spring loaded. You need to get a ratchet, and an extension, usually 3/8 drive and put the end of the extension into the front of the idler pulley and either push or pull to take tension off the spring. This will allow you to slip the belt off the alternator pulley. The slack will be very minimal. Once you get your alternator back on you will once again tak ethe tension off, loop the belt over the pulley on the alternator and then let the idler pulley take the tension up on th ebelt making it tight. If the serpentine belt falls off all the pulleys, you need to route the belt back onto each oulley in the designated manner. If you DO NOT see a belt diagrahm on the front radiator support, then make a drawing for yourself so you know how th ebelt loops over each pulley. Both sides of serpentine belt touch pulleys so the belt is not like old v belts that can only go one way.
