![]() ![]() 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 212° 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 water’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 1900’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.įor 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, “water” is the term used for the cooling fluid. An Important Caution with Pre-Owned Vehicles.What Can Happen if I Use the Wrong Type of Coolant?.#3 – HOAT (Hybrid Organic Acid Technology).Animals love its sweet taste, so even a spilling a small amount on your garage floor can end up in the dog's stomach pretty quickly. Promptly wipe up any spilled fluid as it is highly toxic. Always wear safety goggles when working on your Enclave. ![]() Removing the coolant reservoir cap on a warm engine could cause the cap to fly off at a high rate of speed and fluid to spray out of the reservoir. These coolants will typically say 50/50 or pre-mixed on the front of the coolant bottle. Some coolants will come premixed-that is, you don't need to add any water. Mix the coolant / antifreeze with distilled water so that you have a combination of 50% coolant and 50% water. ![]() Be sure to check your owners manual to determine the correct type of fluid to add - for Buicks, it will typically be in a section titled Fluid Capacities in the back of your manual. The video above shows you where the coolant reservoir in your Enclave is located and how to add coolant / antifreeze. Make sure to check your engine when it is cold for an accurate reading. Engine coolant / antifreeze circulates through your engine to keep it cool in the summer but won't freeze in the winter. Adding engine coolant (also known as antifreeze) to your 2013 Buick Enclave is pretty easy. ![]()
