[Vwdiesel] A/C valve question and wanted

Yes, I would like to know as well.  Must you use a vacuum to suck everything out 
of the system?  How do you do this, is it a special AC guy only tool?
I have a good leak someplace and I want to remove the evaporater under the dash 
to inspect for leaks as you had described in the past, look for dirt sticking to 
gooey stuff.
I will replace the O-rings and re-install, but wondering about the evacuation of 
the system before trying to put more R12 in again.

Then, if it runs for a day or 2 and leaks out again like it did the last time I 
tried to fix it, I will have to put out the extra money for the colored gas and 
the special glasses to see the leak......as it is coming out.

I hope to get the AC to work in the 92Jetta this summer.

On the lines of A/C...

In the Banana Rabbit, I had to disconnect the compressor to pull the engine out, 
due to how the lines were run.  There was actually a bit of pressure that was in 
the system, which says to me that there is potential for the system to work if 
filled.  


In the mean time, I had some A/C work done at my house and I noted that they 
didn't pull any kind of vacuum, just filled the system back up after the work.  


So, I know on a car it is SOP to pull a vacuum on the system before filling, but 
I wonder if it is necessary?  Perhaps the vacuum is just a diagnostic thing, 
making sure there are no leaks.  


Any reason I couldn't get some of the r-12 replacement stuff and fill it up to 
try it out?
