Anti freeze was invented to prevent the water in your block from freezing and cracking your block or heads in very cold weather climates. Later on for marketing purposes they started calling it coolant. This is a marketing tool only as there is nothing in "coolant" that helps your engine run cooler. As we all know water boiles at 212 degrees at sea level. There is an ingrediant in "coolant" that will raise the boiling point about 10 or 12 degrees with a 50/50 mixture. This can prevent a boil over if your water temp gets over 212 degrees. Fact is if your water temp gets that hot then you have another problem anyhow. There is a third reason to use anti freeze or coolant and that is corrosion resistance, and since I live in Arizona that is the only reason that I use it. I have had good results using Red Line Water wetter for improving heat transfer in a cooling system but I have not tried other brands of this type of product. And one more thing about "coolant" if you use Water Wetter to help with heat transfer they recommend for it to be effective that you use plain water or only a small amount of coolant. Hmmmmmm what does that say about your coolant? I also use distilled water in my cooling system to prevent mineral deposits from clogging things up.
