Air Conditioning Conversion Kit for International 1066, 1086 and more - York to Sanden, 990-3572K

Replace your aging York compressor with a modern Sanden-style A/C system using this complete conversion kit from AP Air.

What's Included (SKU: QFS-990-3572K)

• Sanden Conversion Kit (990-357) — replaces the original York piston compressor with a lightweight, efficient rotary unit
• Receiver Drier — new desiccant to eliminate moisture from the system
• Expansion Valve — controls refrigerant flow for optimal cab cooling performance
• Service Valve Kit — retrofit charge port adapters so modern R134a service equipment can connect to the system; also serves as a visual indicator the conversion is complete

Why Upgrade from the York Compressor?

The original York piston compressor is heavy, inefficient, and parts are increasingly scarce. The Sanden rotary compressor offers:

• Less engine load — lighter weight means less parasitic drag
• Better cooling efficiency — especially at low RPMs during field work
• R134a compatibility — works with the modern, readily available refrigerant standard
• Widely serviceable — any shop with modern A/C equipment can service a Sanden system

Installation Notes

• Flush the system thoroughly before installing to remove residual mineral oil from the original York compressor
• Use PAG oil specified for the Sanden compressor — do not mix with old mineral oil
• Replace all O-rings with HNBR (green) O-rings rated for R134a (included in kit)
• Install the included service valve adapters to enable R134a service equipment connection
• Have the system professionally evacuated and recharged with R134a refrigerant
