Hello good day. I'm a shooter, I have a vacuum pump and I have a car that had a crash; Change the condenser and also the compressor, as they were damaged. Now there are things that I miss.
Connect the pressure gauge; Red and blue and yellow to the pump. Activate it by having the knobs that connect to the car open and also those of the pressure gauge for 20 seconds. A quick empty was made to check that there are no losses. Turn off the pump and leave it for an hour, when I returned it is at room pressure (zero for the blue gauge).
I said to myself: of course, I have to close the pressure gauge knobs, because otherwise, it leaks from the same pump, after an hour ... it will be minimal, but it will lose.
I closed the pressure gauge knobs and at the time I returned; the same. I told myself, of course, I should leave the system empty and close the handles that are connected to the car's pipes, maybe there is a micro loss that occurs after an hour.
That is, I made empty and disconnected everything. Supposedly in an hour when reconnecting, empty the hoses and open the car circuit again it should keep the vacuum.
Is that the test? What I want is to test if there are no leaks. I don't have the bottle of hydrogen and I saw that it is expensive. Do I have another way to try it? with compressed air? The system does not have a drop of gas. : roll:
