Besides anti freeze being used to lower the freezing point, it is also an anti-corrosive. Cars out in the south and in desert climates run antifreeze to keep the PH and other such things in the water in balance. Ethylene glycol may lubricate, but it is not used as a lubricant in the cooling system.


How many times do I got to say this BJ, PURE ETHYLENE GLYCOL IS NOT THE BEST AT COOLING. You are talking about the temperature it can take, not the amount of heat. A burning match has LESS heat than a tub filled with ice water. The match has a way higher temp. There is a reason auto manufactures say 50/50 mix.
