![]() De-ionized water uses a process that removes these minerals and particulate, making it ideal for use in coolants. City or well water can contain a certain amount of dissolved minerals and is not recommended to be mixed with coolant. But, a 70/30 mixture of antifreeze and water is not as efficient as a 50/50 mixture because the thermal capacity of antifreeze is not as high as water.Īll antifreeze types require high-quality water to be used if it’s not in a pre-50/50 mix from the manufacturer. A 70/30 mix will lower the freezing point to -67° F and raise the boiling temperature to 235° F. The ratio of coolant can vary, depending on the application or situation, to as much as 70% coolant. ![]() Since water is a natural coolant, when mixed with 50% antifreeze, it improves the heat transfer above what it would be alone. Most consumers will not replace their coolant that often, so new, long-life formulations were introduced. The generally recommended replacement interval is once a year. IAT coolants contain either ethylene glycol or propylene glycol with silicate or phosphate additives to increase its compatibility with metal cooling system components. This traditional-style green coolant, which has been in use forever, provides corrosion protection as well as lubrication to the water pump. The most common variety of antifreeze is an Inorganic Additive Technology (IAT) formula. But, changes to the old one-size-fits-all formula has led to confusion for consumers and even some technicians. Each one is formulated to a specific manufacturer’s specifications to keep their engines at an optimal temperature. ![]() Water gives the antifreeze more surface area to transfer heat to the radiator.ĭifferent types of coolants cover a range of applications from diesel to domestic, Asian and European vehicles. Antifreeze freezing and boiling points depend on the concentration of the dissolved substance. An antifreeze/water mix is used to achieve freezing-point depression for cold environments and also produces boiling-point elevation for higher coolant temperatures. Cooling systems and chemistry have changed a great deal since then, and the need for coolant has also been on the rise in today’s modern engines.Īntifreeze lowers the freezing point of a water-based liquid and increases its boiling point. ![]()
