Detailed Description

Four Seasons 10298SK is designed for A/C service work where the compressor is being replaced and the surrounding system components need to be refreshed at the same time. The kit includes the compressor oil, expansion valve, desiccant bag kit, and sealing components needed to address common wear points in the air conditioning circuit. The included block-type expansion valve uses insert O-ring inlet and outlet connections, and the system is specified for R134a refrigerant.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. It is listed for 2005-2010 Scion tC, 2005-2008 Toyota Corolla, 2008 Toyota Matrix, and 2003 Lexus GX470. Four Seasons 10298SK is a direct service-focused option for compressor replacement on these vehicles.

What It Helps Address

• Loss of cooling after compressor replacement
• Contaminated or aged A/C oil during service
• Leaking seals and O-rings at service connections
• Restricted or worn expansion valve operation
• Moisture control concerns in the A/C system

Installation Notes and Tips

Drain and measure the removed compressor oil before installation, then match the system fill with the specified PAG 46 oil. Replace the expansion valve and sealing components during compressor service to help restore proper refrigerant flow and sealing integrity. Verify R134a system requirements, inspect mating surfaces, and confirm all O-ring and gasket locations are clean before assembly.
