Baby, it's cold inside!

The red one from HF just needs an R-12 to R-134a system adapter, I 
turned one up somewhere, but yes, they are not easy to find at all.

I had that, but I couldn't find the right set of connectors to make it 
work.

So I got this:

And this:

http://www.harborfreight.com/cpi/ctaf/Displayitem.taf?itemnumber=2435

(It was on sale).

I had to replace my condensor because it was shot, and I replaced the 
dryer,
too.  They're only $18 from Adirondack.  I also replaced the O-rings.

The problem I had were that  after screwing on the adaptor from the 
R134a
conversion kit, I couldn't get a good, tight fit from the A/C gauge 
manifold
set.

What I ended up doing was finding the hose from an old R134a kit I'd 
bought
for my Passat.  It had a metal end that "snap-fit" to the adaptor that 
you
screw onto the low pressure side of the A/C system.  It also had a 
metal end
that screwed onto the vacuum port of the Harbor Frieght vac pump.  So I 
used
that to draw down the vacuum for about 2 minutes, until the tone of the 
pump
changed.

I then disconnected the old R134a hose I was using from the A/C, then 
the
pump, and screwed the low pressure gauge from the A/C manifold to it, 
and
hooked it up to the system, where it showed as low a vacuum reading as 
the
gauge would go.  I left it overnight, and it held.

I then broke out the R134a can and fill kit, which looks just like the
picture in the bottom right of this page:

Unfortunately, the ends of that hose were plastic.  I don't think a lot 
of
the first can got into the system, because I ran it for 10 minutes, and 
the
can never seemed to empty.  When I took it off, and opened the valve on 
the
gauge, a lot of gas came out.

I then took the old hose, the one with the metal ends from the old 
recharge
it, and used that, and I could hear the system change tone, and begin to
blow cold.
