    A/C locked up and truck could not run. $1300 to replace a/c system on Expedition, cost $258 to buy part with new belt(old one to small now) and have installed.

      Comments about Dorman - Help Air Conditioning Bypass Pulley:

      Replaced No Good (seized) A/C Compressor which wasn't needed as A/C Lines were all rotted! Was glad this part was available for under $50 as opposed to spending $300 for a new compressor!!

      Thanks!!

      NOTE:(Bolts were too long and bottomed out - had to use 2 flat washers & Lock Washer under each bolt...)

      • Q:

        After installation of about one month this has begun to squeal. Belt is straight and pulley is mounted securely. What do I look for?

          Unfortunately we are unable to diagnose what is wrong with your vehicle without being
          able to be there with your vehicle. We highly recommend taking your vehicle to a reputable shop to have them take a look at it to determine the cause.

      • Q:

        do you have to take the compressor off or does it just bolt on the exsiting pulley?
