The big issue with Vanagon Freon loss is due to the long hoses, which are
not barrier hoses.  It is time to change these old hoses with the new
technology.  Better for the environment, and better for your pocket book!

Subject: AC does loses freon

Hi, my 91 Vanagon's AC has been giving me the fits for a few years now.
Every spring I have to get it loaded with freon.  This year I had my
mechanic take the evaporator down, he changed the expansion valve, put it
rebuilt compressor and fixed a very small leak in the system. The charge is
again low and I don't know what to do because we have checked all joints and
there is no evidence of a leak using a leak detector.  Obviously the freon
is leaking somewhere.  R12 was the original fluid but since we can't get it
anymore he uses something called Freeze 12 which works OK but does not cool
like R12.  Any suggestions, hints, advise???
Cheers
Jaime
