Leave this stuff up to the Ac Pros. Find a reputable AC Shop near you. The system isn't any different from other cars. Make sure to Evac that R12 legally, it's illegal to go releasing all that R12 into the atmosphere. Plus, you'll feel good not putting your future generations in jeopardy.

Mine was already empty in the Euro so I replaced all the o-rings myself and took it to the AC Shop for them to do their magic. There is a specific amount of Refrigerant (R134) and Oil that is put into your system, don't try and guess on this. I blew up a Compressor doing this, it's not worth it.
