[Vwdiesel] engine movement

[David Cook]

Actually, some of the 134a kits have oils that are
okay with the R12 systems.  You can just buy the
retrofit kit (comes with new attachments that screw on
top of the old ones, etc) and go at it.  I thought the
same as you until I was told to use it by the mechanic
at work.

I even used the kit on an older pop machine with
success!

A lot of those other R12 replacement kits have nothing
more than PROPANE that you are adding to the system.

Depending on the system, 134a may not cool as well as
R12, but I really think it just depends on the car--it
cools just great in the Corrado (after having been
converted) and you've gotta turn the a/c down after
not too long.
