Heater hose from water pump to heater core, out of heater core to carburetor heat plate (if it has one) back to manifold

Check the heater water valve. Make sure it is closing fully. There is a ball type fixture that may be seized or broken. This is what the temperature lever is connected to

Also, when you move the upper lever to off, there is a door inside the heater box that should close. Check your cables

My water valve was rusted off completely when I got my truck. Not surprised on a 50-year-old truck. It was a pretty easy/cheap fix.

I put a new heater valve in I thought that would be it I will have to check to be sure that it closes all the way
I been thinking of putting shut off valves in the hoses hoping that will cure the problem
