Ford Repair: SQUEAKY BELT, dayco belts, gates belts

Question
I HAVE A 1988 FORD TEMPO.  2.2 ENGINE.  WE HAVE AN ANNOYING BELT SQEAKING.  I CANNONT DETERMINE WHAT IS CAUSING THE PROBLEM.  THE BELTS HAVE BEEN REPLACED NOT LONG AGO.  I USED DAYCO BELTS.  THE V BELT THAT GOES AROUND THE ALTERNATOR APPEARS SHINY AND GLAZED.  I CANNOT SEE ANYTHING OUT OF ALIGNMENT, ALTHOUGH JUST LOOKING IS PROBABLY NOT VERY ACCURATE.  I OBSERVED THE BELTS AS THE CAR WAS RUNNING.  THE ALTERNATOR BELT APPEARS LOOSE TO ME.  FROM A SIDE VIEW THE BELT SEEMS TO BE MOVING EXCESSIVELY BACK AND FORTH CREATING A WIDE OPTICAL ILLUSION PATTERN.  THE CAR DOES SEEM TO DO FINE AT IDLE.  HOWEVER, SHORTLY AFTER I TURNED THE A/C ON THE SQUEAL PRESENTED ITSELF.  

THANKS FOR YOUR TIME!

Answer
Hello and thanks for the question...I'll try to help.
Nothing against Dayco, but I have never had good luck with them. They are a cheap brand from Auto-zone. I suggest that you use Gates belts. As far as the adjustment goes, you might have to switch to a smaller belt, IF you can't get the correct tensioning out of the Alternator. Go to a local parts store and ask for the correct belt(s) for you vehicle. Also, be sure you tell them your CORRECT engine size..you have a 2.3L, not a 2.2L.
Hope this helps,
Erik
