Detailed Description

Four Seasons 20002SK is an A/C compressor replacement service kit for classic GM platforms that need a coordinated refrigerant-system refresh. It is built around the core service parts commonly replaced during compressor work: the filter drier, TXV expansion valve, compressor oil, and sealing components. The included PAG 46 oil and R134a refrigerant specification make it a direct-service solution for vehicles converted or serviced under that refrigerant standard.

This kit is listed across a wide range of 1968-1974 Buick, Chevrolet, Cadillac, Oldsmobile, and Pontiac models, including Chevrolet Bel Air, Caprice, Impala, El Camino, Monte Carlo, Camaro, Nova, Corvette, Pontiac Bonneville, Catalina, Firebird, Grand Prix, and LeMans, plus Buick Riviera, Skylark, Regal, Cadillac Eldorado, DeVille, and Fleetwood, and Oldsmobile 98, Delta 88, Cutlass, Cutlass Supreme, Omega, and Toronado. This part cross-references Monroe Shocks & Struts (e.g., MUK20285, PK0475) for the same application.

Common Problems This Kit Addresses

• Compressor replacement jobs that require a new drier and expansion valve
• Refrigerant leaks at O-rings, gaskets, or service connections
• Restricted A/C flow caused by a worn TXV or contaminated drier
• Oil service needs during R134a compressor replacement
• Incomplete A/C refreshes on classic GM vehicles with factory air

Installation Notes and Tips

Verify the vehicle’s A/C configuration, especially factory air, front-kit, and serial-number notes shown in the fitment data before ordering. Replace sealing components during service, confirm the system is clean before charging, and match the compressor oil specification to the vehicle’s A/C requirements. The receiver drier/accumulator uses female O-ring inlet and outlet fittings sized at 0.375 in. / 9.525 mm.
