Product Details

This kit is organized for a complete air conditioning repair rather than a single-component replacement. The compressor, filter drier, expansion valve, and oil are matched for the listed Mitsubishi Lancer and Mitsubishi Outlander applications, helping restore proper refrigerant flow and system operation when the original A/C components are worn or contaminated. Four Seasons 4736NK is a direct-fit service solution for vehicles using the MSC105C compressor configuration.

This part cross-references Four Seasons 4736NK for the same application.

Common A/C Problems This Kit Can Address

• Loss of cooling performance from a worn compressor
• Restricted refrigerant flow caused by a failing expansion valve
• Moisture or contamination in the A/C system after component failure
• Noise or poor operation from compressor wear
• System service needs after replacing major A/C hardware

Installation Notes and Tips

Verify the vehicle uses an MSC105C compressor before ordering. Replace the filter drier and expansion valve during compressor service, and evacuate the system before recharging with the correct R134a refrigerant. Confirm all O-ring and pad-mount connections are clean and properly seated before final assembly.
