Glycol is illegal in most (all?) forms of racing because it behaves like oil
when it gets on the track.  Very slick!  Redline claims their water wetter
(dry red crystals, use about 1 tablespoon per gallon) actually improves
cooling over straight water.  I've been using NAPA Kool cooling system
treatment (red liquid) for some time, mixed with tap water at about 20 to 1
with no corrosion problems.  Unfortunately, nobody lists ingredients in
their "magic juice" so I can't tell you what they really are.

As for cooling properties, I think glycol is lousy, so unless you really
need the freeze protection, use some kind of corrosion inhibitor instead and
let the water do the cooling.  Just my $.02 worth.

Adding almost anything to water will increase its cooling ability. Even
straight table salt. However, that won't help any corrosion problem you
have ;-)

The higher the coolant temperature, the more heat it can carry. Except
that you don't want the coolant to boil, so the idea is to raise the
boiling point of the coolant liquid. Pure water boils at 100C --
anything mixed into it will raise the boiling point. It will also lower
its freezing point and therefore stop coolant from freezing in cold
conditions.
