Scott,
I don't think that is quite right. For starters, antifreeze basically
works by putting some junk in the water to lower the freezing point and
raise the boiling point. Here's the real kicker, antifreeze doesn't conduct
heat very well. So you are actually decreasing the cooling capability of
the fluid when you add the antifreeze.
Water wetter works by reducing the cavitation (or bubbles) that form around
the radiator tubes as the fluid flows through the radiator. Therefore,
increasing the surface area that the water is touching and increasing the
heat transfer.
I don't know anything about 40 below, other than it was developed for NASCAR
to cool down their engines.
