Along with R12. Can anyone think of anything else that I should change while in there?
I also need some advice on oil. I have read that if I use Syn. oil, I can change from R12 to R134 if needed.
Last is advice on flush. I know I need it, compressor sounds like it has marbles inside. Is an auto a/c manifold required for this or can I make do without the $50 cost to buy one?
