This has not proven to be completely successful.ДЇor this reason the use of propylene glycol has broadened. In 2012, US antifreeze manufacturers agreed to add a bitter tasting chemical to their antifreeze products in an attempt to mitigate the toxicity issue. However, when used in coolant blends, it is prone to develop bacterial and fungal growth over time.

Propylene glycol, a second and more recent option for antifreeze, also works well for automotive coolant purposes. Always clean up coolant spills to avoid this kind of disaster. Your next door neighborвЂ™s puppy might be attracted to the taste lapping it up, leading to sad consequences. A spill of your carвЂ™s coolant with this particular antifreeze blend onto your driveway could leave a poisonous puddle. Cooling systems must circulate higher flow rates of this coolant to transfer the same amount of heat that water alone would carry.ДЄlso, pure ethylene glycol is sweet to the taste as well as being toxic. Thus when added to water the amount of heat a given volume of this coolant mix can retain is reduced. Ethylene glycol became the new antifreeze of choice for combustion engines.Д®thylene glycol has about one half the specific heat value of water. When added to water ethylene glycol not only lowered the freezing temperature sufficiently, but it increased the boiling temperature as well. In 1926, chemists came up with an enduring answer, a petroleum-based derivative called ethylene glycol. Read Also: Can Gas, Diesel, Coolant, and Other Car Fluids Freeze? Not quite low enough for every winter climate condition. It lowered the freezing temperature of water but was effective down to only -36В° F. The next step forward was a chemical called glycerol. The lowered boiling point using methanol for antifreeze could not be tolerated. Engines achieve operating temperatures at or above the 212В° range and can easily boil water. Unfortunately, this antifreeze also lowered the boiling temperature of water introducing a new and major issue. Methanol was the first coolant additive called antifreeze. And chemists soon found that methyl alcohol ( methanol) could be mixed with water and thus lower its freezing temperature.

These additives focused both on overcoming waterвЂ™s disadvantages discussed above while still retaining the positives that water brings to keeping things cool. Very early in the development of engines, chemists began to modify water with added chemicals to make it a more suitable coolant. Related: Can You Add Water to Your Radiator in an Emergency?

Water encourages corrosion (creates metal oxides or rust) with the materials commonly used in engines and radiators.

And it can also freeze inside a radiator and easily destroy that costly part.

This behavior can crack any engine cooled in winter with water alone. Worse yet, when it freezes, it expands.Water has a freezing temperature of 32 degrees Fahrenheit which makes it unsuitable for engines used in most high latitude climates worldwide.But there are several problems with using water alone that made it then and even now less than the ultimate engine coolant. There is no question that these three factors made water the coolant of choice in the early 1900вЂ™s when engine-driven vehicles came on the scene. It is available virtually everywhere at a remarkably low cost.It has a reasonably high boiling temperature.That is, water can hold more heat per unit volume than almost any other fluid. It has a very high specific heat value.To fully understand the automotive coolants of today, we must first look at the qualities of the pure water once used for this purpose.ДЇor cooling engines, water has some very positive qualities. Simply put, coolant is the liquid that functions to cool the engine in your car. The technical term for this blend is coolant. But the cooling fluid will not be just water but a blend of water and antifreeze. In the description above, вЂњwaterвЂќ is the term used for the cooling fluid.
