Mike,
    Give Detlev at International Auto in Livermore a call at 925-447-8224.
Not sure he handles Freeze-12, but is the most knowledgable, honest mechanic
I've ever met, was trained in Germany and knows vanagons inside/out
including A/C.

Subject: Re: AC System Repair/ Upgrade

After a weekend of driving through some of the hot parts of CA & NV (100 -
103F in places), AC system repair / upgrade has moved to the top of my
'to-do' list (that together with transmission overhaul, but that's a
separate post...). The system was last working fine (well for a Westy that
is) for two summers after a system charge in Spring 2007, but the freon has
obviously leaked away since then. I'm considering conversion to Freeze-12
rather than another R12 recharge (since the R12 will undoubtably leak away
again, adding to the ozone hole..). Advice from anyone who has done this
conversion would be appreciated. I am ready to attempt this myself, but
would consider a shop job if anyone knows of capable AC shops in the San
Francisco Bay Area.

Thanks,
Mike ('87 Westy)
