Ford Mustang: adding r-134a

AC work (this is my own opinion) should be left to properly equipped shops.
The correct procedure would be to recover the remaining refrigerant, check
for and repair any leaks, and recharge the system with the correct amount
(by weight) of refrigerant.

Most folks have been relatively lucky when adding refrigerant from a can,
but it remains to be a roll of the dice. If there is a problem that has
allowed the formation of moisture or acids in the system or a condition that
has allowed the oil to drain from the system, we may be setting ourselves up
for a much more expensive repair in the future. Accidentally overcharging
the system can result in compressor "slugging"... again a spendy proposition
to repair.

Enviromentally, R134a was initially a "stop gap" fix.... replacing R12 ( a
proven problem) only until a safer alternative could be 'designed'. AFAIK,
there have been no definitive studies to prove or disprove any future
concerns regarding our use or misuse of R134a.... given our past
performance, I can't bring myself to say that R134a is a miracle.

I'm with Jim on this one... I'd leave it up to the pros. Just my 2 cents.

just go get the kit for like $12 at your local auto parts store. If you go
to a shop it'll be MUCH more for the same exact thing.

Jim always has the right answer. I've found that out the hard/expensive way
by going cheap then asking around in the newsgroup only to go back and do it
the way Bill S./Jim/Helmut said it should be done. But if you're short on
cash or just don't want to take it to the pros at least get a recharge kit
with a guage. It's east to read and will let you know if the charge is too
low.
