R4 Compressor to 1972 POA Valve?
Hi All,
I'm running a serpentine setup from a '88 TBI Camaro on my 1972 Corvette, using an R4 compressor. I cleaned and resealed the HVAC system and have plenty of R12 on-hand and a New Old Stock compressor.
I know there's a lot of negative feelings for the R4 compressor, but since mine is new, I'll give it a try. I never had one fail before.
I'd like to run an OEM hose set from a later year C3 if it will connect to my stock POA valve (which I want to keep), otherwise I'll have to have custom hoses made. (I'd like to replicate what the factory would have done, if possible)
Has anyone done this?
Thanks,
John

Ditched The POA Valve
When I got my A/C going in my '71 I replaced the POA valve with a "POA Valve Eliminator" so my clutch will cycle on and off like it does on the newer cars. If I recall it cost about $110 five years ago and as it's the same length as the POA valve the new hoses will connect like normal. I believe I bought it from Corvette Central and it comes complete with the low pressure switch, wires, and instructions.
