On my 1947 coolant has started to leak at the bottom of heater where the hose from water pump connects. I hope the hose is bad and not the actual heater leaking. I did not turn the heater on. Also the cut off valve on the top hose in the engine bay is frozen and will need replacing. Do I need to lower the coolant in the radiator to prevent leakage when I replace the hoses and where can I get a new cut off valve? Thanks, ray durham
