Re: A/C Dryer ??
Flow is from the compressor to the condenser, through the drier, to the expansion valve/evaporator.
It looks like it's connected properly

Re: A/C Dryer ??
No orifice tube on the 71 if it is still factory. Factory is a POA system.

Re: A/C Dryer ??
If you are going with 134a, recalibrate your poa valve.

Re: A/C Dryer ??
I Just Got My New POA Valve 134 From Classic. After I Evacuate And Pump Down The System, Question Where Do I Hook Up The Wires The Instuction Are Not Real Clear. The Instructions >>>Replacement for the original POA Valve. Converts the POA System to a Cycling Clutch System like found on most Late Model Vehicles. Saves Gas Milage and decreases length of load on the engine. Easy to install and is compatable with R134 refrigerants. I Also Replaced The Dryer And What Should My Gages Read When Full >>> Low 130 >> Hight 230 ? Also Has And One Used The 134 New POA Valve ? Thank You For Any Help In This Matter Harley03joe ![]() ![]() ![]() ![]() |

Re: A/C Dryer ??
I don't think many people are happy with the POA eliminator pictured. It turns your system into a cycling system that is normally used with a orifice tube.
Originally, and mostly likely still do, you have an expansion valve as the metering device. It's used with a continuously running compressor. The POA helped control the pressure in the evaporator core. More modern A/C systems might use an expansion valve without a POA. By adjusting the expansion valve you might be able to get decent performance without the POA. The switch above would then become a protection device edit to answer your questions. I do not believe you can buy a "new" POA The wire on the switch goes in series with the green wire going to your compressor Google a 134a pressure/temp chart. While running low side pressure should be 35-40 psi.
