Yeah, all you need to change to R134 correctly is a vacuum pump to evacuate
the Freon. The proper way to do this is a shop to capture it that sometimes
will do it for free to keep the R12. If you do not vac it all out, the R12
may react with the R134 to form an acidic substance that can block the
system expansion valve.
No need to do anything else. I did two cars, changing over to R134, the
beginning of the summer including a Golf and a Mercury Topaz for a friend
and BOTH have ran perfectly all summer with just pulling a vacuum and using
the retrofit kit of around 32 bucks. That is all it tells you to do on the
website of the retrofit manufacturer also -to pull a vacuum before changing
over - it uses a premix of ester oil. I have a license for R12 but changed
over anyway the cars have been pretty cold too - I expected them to blow
warmer. R12 on Ebay is NOT fake like someone wrote. I have bought it a
couple of times. I think he just wants to buy it without the 609
certification. "Fake", come on!
