[Vwdiesel] R12 replacement

[James Hansen]

Having done some R-12 to 134 conversions in the farm machinery, I have
noticed no difference whatsoever in operation or function, other than when
service is needed, the 134 is cheap, compared to the "black market" r-12
that's still around...  there were guys driving around selling it to shops a
few years ago like rum runners.
  Propane, duracool, etc work very well for anyone I know that use them...
but leaks for them usually, because that's why they are using it in the
first place- the R-12 leaked out, so you can't really expect the hydrocarbon
based stuff to not leak either...

DURACOOL claims that their product cools 35 % better than 134a, and
marginally better than r12. It is also reasonable priced and requires no
modifications for install. I just bought 3 cans & will try soon. 134a really
doesn't work very well compared to r12, even in systems designed for it.
Also, there are some threads about 134a causing testicular cancer! Given the
choice, I'd prefer to go out in a propane fireball.
And I'd be happy to help your dad get rid of his r12 stockpile.

134a isn't that much harder to install. I've not done it as I don't have all
the tools, but Dad has rolled over his fleet to it and as long as the system
remains intact (my '85 has a blown evaporator), it works fine without having
a flammable gas in the cab. If I recall correctly, it's just some fittings
and a new receiver/dryer. Toolwise, you do have to have a new set of gauges,
or at least new hoses for your old ones. Dad converted all of his cars even
though he was still sitting on a stockpile of R12. Doesn't even know what to
do with it now. Prices dropped because everyone's converting.
