I think you could also use a hand pump to pull a vacuum on the system. I got a "Mighty Vac" from Autozone for around $25-30. I've only used it for bleeding brakes, haven't had to evacuate an a/c system with it. Not sure how effective it would be, or if it would get any of the oils that are in the lines, but it will pull a pretty good vaccum. Probably better than just hoping the freon escapes. Don't forget to replace the a/c drier whenever you expose the system to air, otherwise, there'll be moisture trapped in there. Laters, Brian 1989 Jetta GLI 16v Wolfsburg
