Description
POA update kit — convert GM & Ford A/C to a cycling-switch system (R-134a)
A conversion kit that retires the troublesome POA (Pilot-Operated Absolute) valve on older GM and Ford A/C systems and switches them to a modern cycling-switch setup — simpler to service and a clean match for R-134a.
Confirm your application before ordering. Kit contents vary by system — call 480-507-2229 to confirm the right kit for your GM or Ford vehicle.
Retire the POA, run a cycling switch
The POA valve was used on older GM and Ford systems to hold a constant evaporator pressure. They’re expensive, hard to source, and a common failure point — especially after an R-12 to R-134a conversion. This kit lets you remove the POA and control the compressor with a cycling clutch switch instead, simplifying the system and improving reliability.
