The alternator itself has the ability to put tension on the belt. The upper screw in the alternator that goes into that little support strap, has gear teeth on the front side that mesh into recessed teeth on the strap and it can move up and down the strap to increase tension. If the teeth are missing or not working like mine, just pull the bolt out part of the way move the alternator by hand and put the bolt back in and retighten.

If you have moved the alternator all the way out and the belt is still loose, the belt has stretched and needs to be replaced.
