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?
x15 Coolant sys pressure test. Not losing pressure after 20 min
