Re: verifying a/c charge amount

["content22207" <brobertson@xxxx>]

Buy a gauge. Most parts houses only sell gauges with 134 threads (use
a charging hose) or the quick connect now, but you can easily adapt to
a R12 system by screwing on a retrofit adapter. Don't forget to
unscrew the adapter afterwards or someone may accidentally mix freons.

IMHO R134 has gotten a bum rap. Its perceived ills are probably due to
age of the vehicles being retrofitted. A 20 - 30 year system may give
problems no matter what kind of freon is used.

Drove a 23 year old retrofitted Lincoln to VA to get my new DeLorean
(which is *STILL* up there BTW). Heater core was bypassed due to leak.
Without its moderating influence, temperature from vents was 27
degrees (freon evaporates @ 22 degrees). My evaporator kept icing up
like an old freezer. Had to defrost with outside air every 15 minutes.
Glove box was full of condensed water when I got there. Don't tell me
134 doesn't get cold enough.

BTW: My offer to share Bill's DIY A/C conversion still stands. Why
people mess around with supposed A/C guru's when everything you need
is under your own hood (trunk?) is beyond me.
