Jim,
   Check your chemistry book.   You are right about
the overheating only.   Water has a higher
thermocapacity than most liquids therfore it is able
to carry more heat away from the engine but the
freezing point of water is much higher than the
glycol.
A glycol solution is liquid down to 70 below zero.
Wine will freeze at  40 below  but a good glass of
scotch is still a good glass of scotch.
        bottoms up  gary

Will overheat in the summer and freeze in the winter.
A 50% blend
gives
'maximum protection' both for hot and for cold.  If
the manufacturers
thought that they could get away with selling a
product that was
"preblended" you can bet they would.  For the same
price as the
"unblended" product. ("New! Improved!  Easy to
Use!!!")
