Not that it's terribly important but may be interesting...
Adding table sugar or salt to water will also lower it's freezing point substantially while also raising the boiling point. Melting point depression and boiling point elevation. This happens when virtually anything is dissolved in water. But salt will facilitate corrosion, sugar will cook into caramel, you get the picture.
SPECIFIC HEAT: the amount of heat (in calories) required to heat one cc of substance one degree hotter (in celcius) from room temp starting point, divided by the value necessary to do the same to water
water has a specific heat of 1 by definition
etylene glycol has a specific heat closer to .8 (off the top of my head, didn't look it up)
this is why water is better for use as a coolant, it absorbs more energy to raise it's temp the same amount compared to ethylene glycol
