    when did GM switch from A5 to A6?

    Just curiouse as I have a 1961 in stock, and have been asked if I do A5. I am not familiar with the A5 and was told they are sealed. Well then how or who can rebuild one?

    Dom, I have no clue but if the A5 shows a part# try to enter in a search HERE on gmpartswiki and see what it shows.

    Also, Just noticed this GM A/C Compressor Repair Manual on CF For Sale. Not sure if it may help. It's Dated 1986.(see below)
    https://www.corvetteforum.com/forums...or-manual.html

    Also found this site which appears to show a before/after of restoring the Sealed A5. They say they can rebuild the A5. If they can, I'm sure you could.


    Link HERE to their 1955-1957 Flanged A5 rebuild process.

    Link HERE to their 1959-1961 Sealed A5 rebuild process. Note their "Note" on the sealed compressor....

    * NOTE 1 - A5 Sealed compressors cannot be opened up and rebuild like most compressors. Instead, this is a reconditioning service of the compressor and a rebuild service of the clutch.

      Rich,
      Thanks for all your work helping me. Getting old and not sure I'm going to tool up for the A5.
      Thanks,
      Dom
