So I am messing around with heater boxes right now and I was pressure testing two heater valves I had. I cobbled together some hoses to attach my coolant tester to. One valve did ok, although it leaks slightly around the push rod when it's being actuated. The other leaks badly as the junction of the brass body to the steel bracketry. So in the best Captain Obvious manner, I decided to take it apart! Folded the ears back and removed the bracketry The internals just pull out after that There is a square O ring seal between the hard plastic end and an inner washer. I think if it were replaced the valve would seal up. I've started looking for suitable O rings without having to buy a 100qty. Bead blasted the valve body just for fun
