CD 1952 Overheating cause?

[dterdy]

I have a 1952 CD super wagon. Overheating question: New radiator core, antifreeze, tune/timing, valve adjustment. Starts easily runs and gets hot immediately (based on dash guage) Need to check water pump condition...no leaks. Any other suggestions? Read about "deflector plate" inside engine at water pump condition may be rusted out, don't know. Any suggestions on what else might be the overheating problem?

Yes I have an idea...Have to changed the thermostat ?? It sounds just like what a stuck thermostat would do...Dave
