Resurrected Junk
One of the problems I noted when I got the car was that the hot water control valve had been by-passed. The valve was fused into the closed position. When I remove the link between the vacuum dashpot and the valve body, it still worked. Even with the HVAC doors working properly, I was still getting some heat in the passenger compartment. I began a quest to replace the valve.
I was unable to find a new valve that matched the original valve. The original valve worked like the throttle in a carburetor. I tried one I removed from an old M-body New Yorker. It didn't work out too well.
AutoZone carries a replacement valve that is not like the original. It is a gate valve rather than a butterfly. That's not particularly an asset or a liability in itself. The liability was that the valve was not labelled for input and output. I've found that some valves are sensitive to the direction of flow. After a little testing, I figured out which way the valve would be most effective. Using the mount cut off of the old valve, I was able to get a fairly clean looking install. Best yet, it works!
