Hey guys, I been having a loss of refridgerant problem for a while now. I finally put some UV dye in it the other day. I got me a UV light and ran the A/C all day driving around town. At night I checked it out and found dye coming out of the high pressure line fitting. It's not coming out of the top. It's coming from the sides where it looks like a hex nut. I was wondering if the high pressure line fitting was screwed on or was the hex nut look just there for looks. If it was screwed on, I can just get another one put on or tighten this one right? If it's not screwed on, what do i have to do? Is this gonna cost me $$$? Thanks guys.
