My '54 Conestoga has been converted from a Commander to a Champion and now back to a Commander. The 259 cid engine is overheating with the original 3-tube Champion radiator. The engine was flushed and thoroughly cleaned, new freeze plugs, new water pump, etc. Even so, after idling a while the water temp spikes. It does not appear to be an indication problem----the water is very hot.

I have checked several junk yards and Studebaker vendors and the Commander radiators for the sedans and stationwagons are 3-tube style not 4-tube so I should be OK to use the old radiator.

Any suggestions?

Is the thermostat opening to allow coolant to pass through?

Are you sure that it is overheating? Purchase an infared thermometer, and check the temperatures. Make sure that the temps are uniform between the back of the head, where the sending unit is, and the water manifold at the front of the engine. Make sure also, that you are getting a 30-35 degree drop between the top and bottom tank of the radiator. It is good to have one of these thermometers anyway.

Thanks for the speedy replies. I am relying on the gentleman who is doing the work (Don Gay in Lowpoint, IL) for the information that it actually is overheating. He assures me that the thermostat is opening and that he did use a thermometer to check the temperature. He has a lot of experience working on Studebakers and has done work for me in the past. He is scratching his head over this situation.

I'm just brain storming here, but is he certain that coolant is flowing through the engine and radiator (perhaps something is plugged up)? One easy way to check this may be to open the heater valve and turn the heater fan on inside the car and see if it blows hot air.

I remember there being a topic on re-man water pumps not moving enough coolant,does it have one of those installed?
