I see that no one has replied to your email on your belt chirping on AC
pull in.

There is not necessarily one answer to  your question.

  1. Tired streated belt, glazed belt.  Belt dressing can sometimes help, but
    not necessarily for long.
  2. Using one of the "NEW" metric 10MM belts or sometimes  3/8" can be the
    only one available and all suppliers swear they will work.  "SPOILER ALERT"
    they don't!  The original belts were 1/2" (13MM) wide and rode correctly in
    the AC pulley.and crank pulley.
  3. If you can find a Goodyear "Gatorback" or a Kelly Springfield and they
    are 11+MM wide. Take a 10MM open end wrench to check the width.  If the
    10MM wrench fits over the belt then it will not work for long.
  4. I rarely buy locally and get most belts online.  vbeltsupply.com
  5. For an Alternator belt I use an A56 belt (13MM) from NAPA or Farm and
    Fleet.  Some of the AutoZone Duralast belts are 11.176MM wide for other
    belt locations.  Check, Check, Measure and Measure!!!!!!
