What did you do to your car today?
Got that cleaned up.  Now I need to figure out how the Quick Disconnect is supposed to work.  I can't figure out what o-ring to use in the union part.  There was a black one in the ID of the hose side and I can't get a green one in there.


Sorry, too much work to upload pictures.

OK, Feeling a lot better.

Completed all AC hose connections, sucked the system down and she has been holding full vacuum for the last 2 hours. That is a good sign from what I know.
2 hours of holding a vacuum on a system with as little volume as this is plenty. Nice work. Charge that system up and enjoy the AC. AC is One of my projects for this winter. Took the Mustang out for a drive today (mid 90’s) let’s just say it was a short ride.

73 Grandé H Code. Headman long tube headers, T-5 Transmission, 3.70 Traclok, Lowered 1" all around, Aussie 2v heads w/ 2.19 intake, 1.71 exhaust, screw in studs, full roller cam 608/612 lift 280/281 duration LSA 112, Quick Fuel 750 CFM double pumper, AirGap intake.

You had better luck than me for sure. When I first put the system back on it held vacuum fine and worked fine when I charged it. It developed a leak over the winter and I have not been able to locate the source of the leak. 
One issue I have with the green O-rings is that they are metric and the system was built to inch back then. Metric is all I can find and when I pull connections back apart the O-rings do not look like they are right. They look crushed.
Were you able to find Inch O-rings is so where did you get them?
That is my next task to go back to R-134 so I can find the leak with a sniffer and then after that go back to the Dura Cool refrigerant. 
At shows people ask why would you want AC on a vert. My answer is. You have never owned a vert have you? If you ride around with top down you get cooked for sure. 
On a hot day I can drive up in the mountains and in 20 min. I have the heater on it is much cooler up there.

When a man is in the woods and talks and no women are there is he still wrong??
Hmm interesting question on the o-rings.

First of all I used to have a convertible and I get it.  Yes, if you have a zip down rear window, there can be some cool drives with nice sun shade, but if the humidity goes up you will die at every stop light or congestion point on the highway.

For the o-Rings I used a generic O-Ring kit from O-Rielly.  I seemed to have a great fit for everything except for the quick disconnect  fitting near the sight glass.  I ended up having to use a buna O-ring from a kit for that fitting. If I start leaking, that will be my first look.

A couple questions.  Have you tried the UV leak kits from the Auto parts stores?  They come with a dye shot, a UV pen light, and Goggles.  If you cant see anything, it is likely your evaporator.

Tell me about the Dura Cool, what do you know about that?  I want to get as cold as I can at the lowest pressure I can.
