Four Seasons 20148SK A/C Compressor Replacement Service Kit

Four Seasons A/C Installer Kit for Ford and Lincoln

Four Seasons 20148SK is an A/C compressor replacement service kit built for select Ford and Lincoln applications with R134a refrigerant systems. It combines the core service components needed during compressor replacement, including PAG 46 compressor oil, an expansion valve, an O-ring/gasket pack, a desiccant bag kit, and a cap and valve kit.

As part of the Four Seasons A/C Installer Kits line, this kit is organized for service work where the compressor circuit is being opened and the system needs the related sealing and metering components replaced at the same time. Part number 20148SK is listed for multiple Taurus, Flex, Explorer, MKS, and MKT applications.

Detailed Description

Four Seasons 20148SK is a service-focused A/C kit for vehicles using R134a refrigerant and a block-type expansion device. It is built around the components commonly replaced during compressor service, helping restore proper refrigerant flow, sealing, and moisture control in the system. The included PAG 46 oil matches the specified compressor oil type for this application, while the desiccant bag kit and sealing components support a complete A/C repair workflow. This part cross-references Monroe Shocks & Struts (e.g., 550637, MUK20139) for the same application.

What It Helps Address

• Loss of cooling after compressor replacement
• Refrigerant leaks at seals, gaskets, or service connections
• Moisture contamination in the A/C system
• Improper refrigerant metering through the expansion valve
• Service issues tied to worn or contaminated compressor-related components
