I'm in the process of changing my system BACK to R-12.
It's been 134 since I've owned it and it's worked fairly well but I'd like more out of it. Before anyone points it out, yes I will be changing the rec/dry, expansion valve, flushing the system, pulling a vacuum and recharging it properly with my new mastercool gauges (all bought from a/c kits)
Anyway, the high side fitting is on the muffler line by the condenser and the low side is on the compressor. The prior owner had right angle R134 adapters on both ports. I've removed both of these adapters but it appears I need to install a schrader valve in each port. Is this correct? This is one thing I didn't anticipate.
My old rec/dry also has two low side ports on it that you can't really access while it's installed on the car but now that my old one is out can I just remove the schrader valves from it and re-install them on the above mentioned ports? Thanks.
With R-12 I'd be leery of used valves that might leak. You can buy new shraders at any decent parts store. Make sure to specify A/C ones as they have a different kind of rubber in the seal than tire ones.
Thanks for the response. I forgot to mention that my current rec/dry that I removed is only 5 yrs old so the valves in it aren't too old. However, as you mentioned it's probably a better idea to just buy new. Heres what I'm not clear on: Are the schrader valves for low and high side the same size? Or do I need to specify different size? I know externally the service ports are a different size so one doesn't mix them up but I'm not sure about internally.
