On my 90 VW Passat there are a total of 4 bolts that hold the alternator in place. Two at the top left are associated with the slotted metal bar that is used to slide the alternator back and forth to slip off the belt. The other two at the bottom (right and left) of the alternator are what you need to loosen to allow the alternator to pivot back and forth along the slotted bar. Loosen the top bolt first then the remaining two at the bottom to release the tension. You may need to use minor (hand) force to pivot the alternator then slip off the belt. Note you will need some long box mm wrench's to reach the bottom bolts. Remember also if you end up removing or changing your alternator that you disconnect the negative on your battery first.
You must first loosen the alternator, do not remove it. remove the alternator tension screws top and loosen the bottom screws DO NOT REMOVE push the alternator toward engine, for the a/c belt you must loosen the belt tension pulley and move it. replace in reverse order

You have to loosen the tension on the belt by loosen the nut normally found on the pulley located by the motorblock, manifold or even by the alternator pulley it's self.

Loosen the alternator tensioner bolt. You will be able to slide the alternator either way to adjust the tension on the belt.

My suburban has a automatic tensioner therefore I need to do is take the tension off with a long wrench and slide the belt from underneath it and replace it with the new one. The tensioner is right by the water pump. If not then you will need to loosen the alternator bolt and drop the alternator to loosen the tension. Trust me manuals can be your best friend!!
Disconnect the 1982 Regal alternator. Loosen the alternator bolts and slide to release belt tension. Put new belt on ( you may have to remove other belts to gain access) and pull the alternator sideways to put medium tension on the belt while tightening the bolts. Reconnect the battery.
