FWIW, water is a better coolant than anti-freeze. However it does bad things
to your cooling system - rust, corrosion and - if it freezes solid -boom. A
mixture of 50/50 is touted by the chemical manufacturers because it 1) ensures
that the inhibitors etc. in the anti-freeze are there to prevent those
problems and 2) it sells more of their product.
But 70/30 (water/antifreeze) works ok for me in the Florida summer. Seems to
give enough protection. (I also use water-wetter.) As for winter - if we had
one in Fl, I would go to 50/50, which is what I used to do in the Northeast US
and in Germany/Italy years ago. Cheers.
