Cooling System Additive
Not going to argue. If it's on the internet it has to be true. Even if it is true, ethyl glycol is a lubricant. Lubricants reduce friction. Friction creates heat. Therefore, if I remember my physics properly, adding coolant to your water will reduce friction and heat. However, the best explanation I have seen is this:
As water boils it expands and also releases gases dissolved in it.Gas expansion due to heat is way more than liquid expansion. Your car cooling system is a closed system and this expansion causes pressure build up. At some point some thing has to give way, either the water pump, hose, radiator or hopefully radiator cap.
Coolant is made up of mainly TEG ( Tri ethylene glycol) and silicates. TEG has a boiling point above 320f and low expansion due to heat.
Either way in my case it's a moot point. I live in Minnesota. If I don't use antifreeze, I'm buying a new block. I'm assuming you live in a more comfortable climate, which makes me a little jealous.
