Product Details

This A/C compressor replacement service kit is organized for common HVAC repair procedures where the compressor circuit, expansion valve, and sealing components are serviced together. The Four Seasons 20252SK package supports R134a systems and includes PAG 46 compressor oil, making it a direct service-focused choice for vehicles that require this oil specification during A/C repair. The Four Seasons A/C Installer Kits line is aimed at compressor replacement and related air conditioning service work, helping technicians replace key wear items in one application-specific kit.

This part cross-references Monroe Shocks & Struts (e.g., 550798, MUK20037) for the same application.

Common Problems This Kit Addresses

• Loss of cooling performance after compressor replacement
• Leaking A/C seals or O-rings at service connections
• Restricted or faulty expansion valve operation
• Moisture contamination in the refrigerant circuit
• Service-related refrigerant system reassembly on R134a vehicles

Installation Notes and Tips

Verify the vehicle uses an R134a system and PAG 46 compressor oil before installation. Replace sealing surfaces carefully, follow the vehicle service procedure for oil balancing, and evacuate and recharge the system after repairs are complete. Confirm the expansion valve style and connection type match the application before assembly.
