Product Details

The Four Seasons 10447SK service kit is a compressor replacement support kit for R134a systems that require PAG 150 oil. It is built around the components commonly replaced during A/C compressor service, helping restore proper refrigerant flow, sealing, and system preparation on vehicles such as the Chevrolet Caprice, Chevrolet Impala, and Cadillac Fleetwood. The included accumulator, orifice tube kit, and sealing components make this a practical choice when servicing the A/C system on the listed GM platforms.

This part cross-references Monroe Shocks & Struts (e.g., MUK10283, PK0074) for the same application.

What It Is Used For

• Replacing A/C compressor-related service components on R134a systems
• Addressing refrigerant flow restrictions caused by a worn or contaminated orifice tube
• Restoring sealing at O-ring and gasket connection points
• Servicing accumulator-related wear in the air conditioning circuit
• Preparing the system with the correct PAG 150 compressor oil

Installation Notes and Tips

Verify refrigerant type before installation; this kit is specified for R134a systems. Confirm accumulator fitting style and dimensions against the original part before assembly, and follow the vehicle service procedure for oil balancing, evacuation, and recharge. Replace all accessible seals during service and inspect the compressor, lines, and related A/C components for contamination or damage before reassembly.

Quality Assurance

Four Seasons backs this A/C service kit with a limited lifetime warranty. The 10447SK is cataloged for the listed GM applications and built to match the service requirements of vehicles such as Buick Roadmaster, Cadillac Commercial Chassis, and Chevrolet Caprice.
