How do you install 88 Dodge Aries Alternator belt?

First you will want to loosen the alternator. To do this you will need to loosen the bolt holding adjustment bolt in place. This is right under the alternator. After loosening this bolt, you can use the adjusting bolt to loosen the alternator and the belt should slide right off. Then you can put on the new belt and tighten the alternator using the adjusting bolt. After the belt is to the proper tightness, tighten the bolt directly underneath the alternator to keep the belt tight and from becoming loose.
