Did coolant pressure test. Found coolant leak from clamps being loose around hose from thermostat housing. Tighten them up and leak went away. I had it at 15 psi. It never came down from 15. What would cause it to not release pressure?
Wasn’t thinking I guess. I had watched a video and remember them saying you pressurize it and wait 5 minutes to see if how much pressure you lose . So I assumed after 5 minutes you slowly start losing it.
Cooling system shouldn't loose pressure.
CAC on the other hand, we'll it shouldn't loose pressure but I wouldn't expect it to hold pressure forever. I mean it would be great if it did but some loss is acceptable
