Well I finally buttoned up the passat and pumped it down.
I had one major leak which I immediately found. Tightened her
up and pumped her down to deep space vacuum twice.
Second time vacuum didn't creep up at all for over
My observations on the whole process:
Not too bad. The fundamentals of the
vacuum gauge set were a bit mystifying.
I never found a diagram depicting exactly
the logic of the valve. I understand them
now but I had to read several articles
before it became clear.
The side-can tap --- can't say I understand
the appeal. First can I tapped leaked
all over the place. After trying to be a good
do-bee and have the original residual refrig sucked
out at a station, I felt pretty stupid
using a can-tap that must have squirted out
30% of its contents on my glove covered hand
a big disappointment.
Is there something wrong with my can tap?
I went back to a top mounted filler that
I had for subsequent cans or refrig.
Car is blowing cold, but sitting still---
I still need to replace struts, brakes, shocks.....
Thanks for the help
As long as the rubber grommet is around the piercing probe the Mastercool side can tap we use do not leak.
