Maybe this is a stupid question, but what is the right way to release pressure at the end of a cold radiator pressure test?
Yesterday I did a test on my truck, it gave me some useful insights, So I was ready to release it. I used the thumb actuated release, and a lot of coolant shot out all over. I thought I might have more control if I removed the actual hose, but when I did that, there was a fountain shooting upwards.
I had watched youtube and the folks doing it had nowhere near the mess or release. One had indicated to top up the system vs compressing air in the radiator. So it seems that they should be full. My radiator was completely full.
So am I doing something wrong? Should I leave some headspace in the radiator? Are the coolant fountains just edited from youtube? I get it that the energy has to go somewhere, but I’m also surprised that so much shot out.
Thanks!
