Cool/Heat: 1962 control valve for heater

[Jimmie]

I suppose that the capillary tube on my 1962 water control valve serves as a thermostat to MAINTAIN the temperature inside the car based on the position of the control lever on the dash of the car. If I put a simple valve (that I can adjust from off to full on) without a capillary tube will I encounter a problem. Am I wrong to think that I can control the temperature in the car by regulating the amount of hot water that passes through the heater core, without the capillary mechanism?

Is there an inexpensive generic valve out there which I could use to replace my leaking valve. This is a "driver" and being original where it does not show is not a problem to me.

Now, my 50 is a different story!!!!!

Get a kit from NAPA and rebuild your old valve, bout an hours work!

The Studebaker Vendor Replacement "Ball Valve" should work manually just as well as the Ranco Valve did, it just pulls for closed instead of open.
The big plus is, they last indefinitely because of their simplicity of design.

Installed the referenced vendor ball valve on a Champ and it works well.

I think the capillary tube is there for safety reasons, if the engine coolant boils and the valve is open it will close the valve to prevent scolding steam from entering the passenger compartment.
