Product Details

Four Seasons 40028SK is an A/C compressor replacement service kit built around the service parts commonly needed when restoring the air conditioning system on a Ford Focus. The kit is organized for R134a systems and includes PAG 46 oil, an orange standard orifice tube, and sealing components to support a proper compressor replacement service. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. Fits 2000-2002 Ford Focus, N/A; Fits 2003 Ford Focus, N/A; Fits 2004 Ford Focus, N/A; Fits 2005 Ford Focus, N/A; Fits 2006 Ford Focus, N/A; Fits 2007 Ford Focus, N/A. The Four Seasons 40028SK is also listed for select 2000-2007 Ford Focus applications with notes that vary by model year, including hose assembly and replacement tube requirements on certain vehicles.

What It Helps Address

• Loss of A/C cooling after compressor replacement
• Contaminated or worn compressor service components
• Leaking seals or O-rings in the A/C circuit
• Restricted refrigerant flow at the orifice tube
• Service mismatches when converting or restoring an R134a system

Installation Notes

Verify the vehicle’s model year and service notes before installation. Some Ford Focus applications require a new discharge and suction hose assembly, and 2004-2006 notes call for a replacement tube kit when replacing the orifice tube. Confirm the accumulator fitting style, orifice tube specification, and refrigerant type before charging the system. Use proper A/C service procedures, evacuate the system, and replace sealing components during compressor service.

Quality Assurance

Four Seasons backs this A/C service kit with a limited lifetime warranty. The 40028SK is built for the specified Ford Focus applications and packaged with the service components needed for a compressor replacement on R134a systems.
