1990 AC question
Does any one know, is R134a compatible with R-12?
Thanks

Re: 1990 AC question
I assume you are wanting to mix.. then no.. if you are recovering and installing r134a then your hardware can handle it
I will mention I noticed a bigger load with R134a due to a higher head pressure of R123a
