  • System contamination concerns after compressor failure when flushing is required
  • Restoration work on vintage Buick Skylark, DeVille, and Fleetwood A/C systems

Verify the vehicle’s compressor style, pulley configuration, and position before ordering. The fitment notes call out A6 compressor applications, double groove pulley requirements, expansion valve usage on several listings, and a before-serial-number note for 1968 Cadillac DeVille and Fleetwood. For best results, follow the listed service steps for flushing and oil selection during A/C system repair.
