'35, need electric fan help

[Old Ford Addict]

Either you have a pressurized system / radiator or you have a stock / un pressurized one.
Is the over flow tube coming from the neck or the tank?

Old Ford Addict, over flow tube comes out the top center of the tank from a raised brass boss. I believe the boss is part of a relief valve. I'm sure it is pressurized, just don't know what it's rated at 3, 4, 5, 6, or 7 PSI. my paper work doesn't indicate, nor does the cap. I have an e-mail into the Brass Works referencing my invoice with that question.

Something I'd like to know for my records but don't really feel it's an issue as the shroud or a combination of that and re-torquing head bolts and retarding the timing seems to have resolved all the overheating / relief valve blowing coolant and steam issues. System stays under 180 even at idle for hours as tested now.

From your picture it looks like the over flow comes off the top tank like a stock 35 Ford. It's good to see you got some improvement in cooling. you have to understand running at 70 degrees outside temperature is not the same as running at 100 degrees. With your small fan it isn't going to cool at 100 like you got at a cooler temperature but it should not over heat from what you described. I see just the water pumps and coils were on the site I suggested. You could email [email protected] for info or I can post his product sheet. G.M.

Harbor freight has sale on laser thermometers right now for under $30. Not real high tech but serve the purpose.

Thx for the heads-up Keith oh

When you buy a laser thermometer try it in the store. Counter top and other objects should read what the store thermostat is set at. I have seen a few that were way off. G.M.

Thx!

You may have had a cylinder leak as Brian suggested ,a fan shroud can add heaps to the equation ,most modern electric fans have a shroud .I would say retarding the timing has done nothing in fact retarded timing can aggravate the situation slightly over advance timing as a rule doesn't but retarded does .The optimum position for the fan is in the hottest part of the radiator and that's at the top as the water is expeld out the top of the motor .Ted
