Well, patience and two weeks of soaking in liquid wrench paid off and I finally got the sylphon(?) valve out of the radiator. For some reason the shaft and the springs were fairly rusted. I've been cleaning them up and have cleaned up the exterior of the valve. I am curious as to how it actually works. I assume there is some sort of spring or something that expands as it gets hot? I lowered the exterior into boiling water and did not see the shaft move so I'm thinking it is not functioning. Is there any way to disassemble the valve to clean and repair it?
