So search with my name. You will find tons and tons of R134 Retrofit information....

I am certified for R12 but I wouldn't spend the money for it. I have done hundreds of retros without any problems. I can get R134 to cool just as good, if not better then R12 in an R12 system!!! Just needs done properly. <img src="/forums/images/graemlins/smile.gif" alt="" />
