Pure water transfers heat slightly more effectively than antifreeze,
but it boils at, well, the boiling point -- 212 degrees F. By using
antifreeze in the mix, you can raise the boiling point of the mixture
several tens of degrees (as well as lowering the freezing point quite
a bit).
Also, Ken -- and I have to admit I haven't fully followed this
thread, so bear with me -- are you SURE that the car is actually
overheating? I have a 1977 Spitfire, and for the first two years I
had it I thought it was always on the verge of overheating. The
gauge would go WAAAAY over even on mild days. And I did everything,
flushing the cooling system, having the radiator professionally
cleaned & tested, replaced the water pump, running with heater on.
Even tried to get an oil cooler for it. The guy I almost got the oil
cooler from said, well, have you checked your gauge. No, I hadn't.
Lo and behold, the car was fine and the gauge was bad.
Just an idea, and my 2 cents' worth.
