Product Details

The Four Seasons 20090SK A/C Compressor Replacement Service Kit is a service-focused solution for select Nissan Altima models. It brings together the major replacement components typically addressed during compressor service, including the filter drier, expansion valve, compressor oil, sealing components, and cap and valve kit. The kit is configured for R134a refrigerant systems and uses a block-type expansion device with insert O-ring inlet and outlet connections for the specified application.

Compatible with 2003-2006 Nissan Altima and 2002 Nissan Altima from 4/02, this kit supports common A/C repair workflows where the compressor is being replaced and related service parts are being renewed at the same time. Part number 20090SK is also referenced by 550534, MUK20197, and PK0046 for the same application.

Common A/C Issues This Kit May Address

  • Loss of cooling after compressor replacement service
  • Contaminated or worn A/C service components in the refrigerant circuit
  • Leaking seals or O-rings at service connections
  • Restricted refrigerant flow related to a worn expansion valve or filter drier
  • Need to refresh compressor oil during A/C system repair

Installation Notes and Tips

Verify the vehicle build date before ordering, since the 2002 Nissan Altima application applies from 4/02. Confirm the system uses R134a refrigerant and match the expansion device style, inlet/outlet connection type, and receiver drier/accumulator mounting style to the original components before installation. Replace sealing surfaces carefully and follow standard evacuation and recharge procedures after service.

Quality Assurance

Four Seasons backs this A/C service kit with a limited lifetime warranty. The 20090SK is built for the listed Nissan Altima applications and packaged as a service kit for compressor replacement work.
