On most cars, the upper alternator-mount usually has an elongated hole or slot with a bolt that goes thru it and the alternator-housing. To loosen/tighten the alternator-belt, just loosen this bolt a little and the top of the alternator can then be swiveled to alter tension on the belt ...when the belt is tight enough (you can only move it 1/4" when pushing at a point that's equal distance between 2 of the pulleys, hold it in that position and tighten the bolt. Sometimes if alternator is difficult to move, it can be pried (and held in position) with wood-handle of a hammer (or other non-metallic item) placed between alternator and the mount.
