R134a A/C conversion for 93 626
I have heard that the two refrigerant operates in different pressure and the old system may not hold the higher pressure. Also I heard that you need to change the compressor oil to convert to R134a but these conversion kits claims that you don't need to open the A/C system...
Any advice will be appreciated.
