My heater control valve is stuck in the hot position and the operating arm is broken off. By a PO. Even with the top down, it gets downright HOT in the cab. So yesterday and today I drained my coolant, flushed the system, made up a new heater control valve assembly and assembled it. See attachment.
Parts required are (1) 1/2" ball valve, female at both ends and (2) 1/2 male threaded barb fittings and (2) additional hose clamps.
My valve conversion will work nicely as long as the original valve will pass a reasonable amount of hot water, regardless of the condition of the insides of the valve - and you do not have to remove the old valve!
I removed the valve-to-heater hose, measured it,cut it to two lengths that lets the valve sit in a relatively clear area. There is enough give to the hose to allow slipping it over both the heater nipple and the valve nipple. Clamp it all together, add your coolant and Voila! you can control the heat again.
If the heater doesn't pass enough hot water, it will be necessary to gut it and then do as above. I am sure someone will have the URL that will lead you to an earlier article for doing so in that case.
