Well I got the system running for about 2 days and it leaked down again....I kinda figured it would because it would not hold a vacuum.....BUT the dye helped and I found the other leak at the compressor....so I replaced it....
Now it holds a vacuum so I should be ready to go.....at least I thought I was.....
I pulled a vacuum on the system for about 1.5 hours.....and then recharged.....my high pressure is around 250 and the low is about 40.....but it is not cooling....at least not very well....
The only thing I can think of is I did not leave the vacuum on long enough....think that is the problem?
