    Comments about Dorman - Help Air Conditioning Bypass Pulley:

    Installed on an 01 Ford Tarus.
    Had to grind down the 2 lower bolts (about 1/2")to fit, added washers due to not being supplied. Might have added some lengh to travel on belt because it was tight to install.

    The pulley was easy to install, but luckly it was a perfect fit and lined up on my first try, for there were no directions explaining what the extra spacers or washer were for.

        • CUSTOMER CARE

          A:

          If you are referring to the suction hose or the line that goes from the accumulator to the compressor, you will have to install protective caps on the open lines (while installing the Dorman - Help Air Conditioning Bypass Pulley - Part No. 34166). For any further assistance please feel free to call us at: 1-877-238-2623 or visit the nearest Advance Auto store and one of our representatives will gladly assist you with any questions or concerns you may have.

          Are you asking if this bolt right into place of the A/C compressor? Or are you asking if an A/C bypass pulley can be taken off and replaced with the A/C compressor.
