I put the lines under pressure via the gauge on my ac refill can. When I came back the lines were no longer under pressure. I used the UV light to see where the leak is coming from. I can not seem to locate where the leak is.

I just recently changed out my ac compressor and radiator. I had to move the condenser to the side. I was thinking that I may have put a small crack or pin hole in the line but I dont see any uv dye coming out. I checked the compressor housing and nothing is comming out from there either.

Does anyone have any suggestions. I have not turned the car over yet. I need to put coolant back in the car. I will be doing this tomorrow.

 

I just put the car under pressure again, this time I went over the recommended pressure setting to hopefully get some idea of where this mysterious leak is.

Nothing. It has been 10 minutes let me go and check the pressure......its dropped about 10 psi, it seems to be dropping 1psi a min. That is a very small leak. Is it possible for the compressor to lose pressure from inside. And if it is loosing pressure, then where is the dye going?
