Detailed Description

This Four Seasons A/C compressor kit is cataloged for Cadillac DeVille, Cadillac Eldorado, and Cadillac Fleetwood models from the 1960s that use the specified A6 compressor setup.

  • Loss of A/C compressor function
  • Noisy or worn compressor operation
  • Poor cabin cooling performance
  • Service replacement for an aging reman compressor setup
  • Fitment matching for classic Cadillac A/C repair

Installation Notes
