There are two bolts on the alternator one long that holds the alternator onto the vehicle and one short that adjusts the belts to tighten and loosen. Loosen both bolts, this allows the alternator to tilt letting you remove belt. Pull it back into place and tighten. Let it run for at least 15 min and recheck slack in belt.

If this is a serpentine belt; Loosen the tension on the belt tensioner, pull off old belt, put on new belt, leave slack at tensioner, pull back tensioner, wrap belt on tensioner, release pressure

On most alternators there is an adjusting bolt and a pivot bolt , both bolts must be loosened slightly to enable you to move the alternator , After the two bolts have been loosened , move the alternator ( toward the engine to loosen the belt ) (away from engine to tighten the belt ) You might have to move other belt driven components in the same manner as for the alternator Install belts adjust tension on belts ( It will often be necessary to use some sort of prybar to move the components while the belt is adjusted ,If this must be done to gain the proper leverage , be careful not to damage the components being moved or the part being pried against . ) Belt tension of each belt is checked by pushing on the belt at a distance halfway between the pulleys ( push firmly with your thumb and see how much the belt deflects ) A rule of thumb is that if the distance from pulley centre is between 7 and 11 inches the belt should deflect 1/4 inch , 12 to 16 inches 1/2 inch . A serentine belt ( the tension is controled by a tensioner ( loosen tensioner replace belt ) For better installation instructions go to the libary and check out a book or buy a Haynes Repair Manual for your make , year of car hoped this help you out

If you have only one external belt on your car, it's probably a serpentine belt. There will be a tensioner that needs to be released using a breaker bar or some other tool. With the pressure released it should just slide off... make sure you remember how it went on - maybe take a picture. Now if it's more than one belt you've got... usually there's a way to move a component driven by the belt. Usually the alternator itself swings a bit if loosened to slack the belt. Note: It's recommended to replace the tensioner either at the belt change, or 60k or so.

This really depends on what you are changing it on but i bet there is some sort of a tensioner that you have to relieve pressure and reroute the belt the way it came out and release the tension back on the belt
