[ROVERNET - UK] SD1 AC Refurb

[Kent Kinard]

Hi Vic,
The system is a Frigidaire (GM) VIR (valve in receiver) 
type system with R4 compressor like most GM cars of the 
late seventies.  I think if it were mine I would spend the 
money and buy R12 to put in it as it sounds like it is 
tight with little or no leakage. See if it will hold 
vacuum.  I have never tried to convert a VIR system to 
R134a and have had conflicting advise as to how difficult 
it might be.  Sorry I'm not more help.  Maybe someone else 
will chime in.

Roverefrigeratedly,
Kent K.
