Product Details

The Four Seasons brand line PAC-Kit w/ Reman Compressor is organized for targeted air conditioning service, helping technicians identify the correct compressor package for the listed vehicles. Part number 6475R is specified for classic platforms that require an A6 compressor setup with a 5-3/4 inch pulley, including the 1981 Chevrolet Bel Air and Pontiac performance and intermediate models from the late 1970s. If you are sourcing a remanufactured A/C compressor kit for a 1977-1979 Pontiac Firebird, 1977 Pontiac Grand Prix, or 1978-1980 Pontiac Grand Am, this application-specific listing supports direct catalog lookup.

What It Is Used For

• Replacing a worn or failed A/C compressor in listed Chevrolet and Pontiac vehicles
• Restoring refrigerant circulation in an automotive air conditioning system
• Addressing compressor noise, seizure, or loss of cooling output
• Correcting fitment issues on A6 compressor applications with a 5-3/4 inch pulley

Installation Notes and Tips

Verify the existing compressor style, pulley diameter, and vehicle application before ordering. Confirm the listed notes for your exact model, since fitment is tied to A6 compressor systems and specific HVAC configurations. For best results, inspect the rest of the air conditioning system during service and follow standard evacuation, flushing, and recharge procedures required for compressor replacement.
