I have an 89 300e that I converted from R12 to R134 last summer. I just replaced my condenser and am now re-charging my a/c system.
My question is what should the settings be on the gauges for 134? With R12, I was around 150 on the low side and 20-30 on the high side.
But I'm not sure where I need to be with 134 gauges
