" Back in the day, when I was racing formula fords, for engine coolant we used
" water (distilled) and water pump lube with maybe a tad bit of antifreeze in
" the coolant. I never had any overheating problems, and had to tape over
" radiator openings just to get the heat in the engine. antifreeze is just
" exactly that, and it actually lessens the coolant systems efficiency. We all
" use it for the freeze protection and it does help the boil over protection
" too, but it's less efficient at transferring heat.

this is still the favorite, and some tracks require it as antifreeze
is slipperier especially if there's any oil.

my first demonstration of the cooling power of water was in my first
american, a '66 199.  i let the antifreeze go too long, i let the
heater hoses go too long, and one day the hose blew off the intake on
the highway.  i got it to a gas station but not before it'd pumped
most of the coolant out.  i refilled it with water [all they had at
that hour], stuck the hose back on, crossed my fingers and drove on my
way.  it didn't blow off again!  it didn't blow off for several days,
but as soon as i drained the water and refilled with antifreeze mix it
blew off after warming up.  that's when i figured out my old hoses
were all rotted inside and i needed new ones.

pure water had just enough more cooling power than antifreeze mix that
my system didn't develop any pressure.

" To get the oily crap out of your cooling system go to your local Home Depot
" or something and get some Tri-Sodium Phosphate. I believe it is alkaline in
" nature and a caustic.

sounds about right, but it should be a pretty -mild- caustic.
