YOUR TENSIONER MAY BE WORN--NO LONGER TENSIONS RIGHT
MAYBE A PULLEY IS NOT IN LINE (FLOPPY--INSTALLED WRONG)
DO ALL OF THE PULLEYS TURN FREELY W/ THE BELT OFF............EXCEPTION: CRANKSHAFT PULLEY
IF YOU HAVE A PULLEY THAT BOLTS ON----ARE THE BOLTS TIGHT?
DOES THE CLUTCH (INNER MOST PART OF THE A/C PULLEY) TURN FREELY W/ ENGINE OFF----ENGINE OFF---ENGINE OFF......USING YOUR FINGERS?
...........WHEN THE A/C OR DEFROST IS TURNED ON----THE CLUTCH ENGAGES THE A/C COMPRESSOR---BOTH SETTINGS USE THE COMPRESSOR
THE A/C CLUTCH PULLEY MAY TURN JUST FINE WITH IT FREEWHEELING........BUT WHEN YOU TURN ON THE A/C OR DEFROST-----IF THE COMPRESSOR IS "LOCKED UP" (BAD)----SUDDENLY THE PULLEY WON'T TURN------CAUSE IT'S NOW COUPLED TO THE PART UNABLE TO TURN.......THIS MAY SLING A BELT TOO!
