First I am looking for any kind of tensioner pulley or an adjustment screw for the belt. I found the one for the PS/AC belt (which is not installed) but not one for the alternator.

Thanks

When looking at the alternator, you should see a long slotted bracket mounted across the alternator just behind the pulley. There's a long tension adjusting bolt that screws into the end of the bracket then through a pivot that has a locking bolt. Loosen the locking bolt and turn the tension adjusting bolt to either tighten or Loosen the belt tension.
