Product Details

Four Seasons 10704SK is an A/C compressor replacement service kit for vehicles that use an accumulator-style system with R134a refrigerant. The included PAG 46 oil supports compressor service requirements, while the accumulator, orifice tube kit, and sealing components address the parts commonly replaced during an A/C overhaul. This part cross-references Monroe Shocks & Struts (e.g., MUK10028, PK0210) for the same application.

Common Repair Uses

• Replacing worn A/C sealing components during compressor service
• Restoring proper refrigerant flow through the orifice tube circuit
• Addressing leaks at O-rings, gaskets, caps, or valve connections
• Servicing an accumulator that no longer supports proper system operation
• Completing an R134a compressor replacement on Silverado and Sierra trucks

Installation Notes

Verify the vehicle uses R134a refrigerant and PAG 46 oil before installation. Confirm accumulator dimensions and P-nut fitting style against the original parts, especially on 2006-2007 Silverado 1500 and Sierra 1500 applications noted with a drier without service port. Replace sealing surfaces carefully and follow the vehicle service procedure for evacuation, charging, and leak checking after assembly.
