One of the key benefits of propylene glycol is non-toxic. Ethylene glycol is perhaps the most common because of good antifreeze properties and availability. Glycol (ethylene or propylene glycol) is added to water to withstand freezing temperatures and to raise the boiling point so that the engine stays cool during operation. Since vehicles in many parts of the world experience ambient temperatures well below ‘freezing’ during winter, and engine operating temperatures can reach well above water’s boiling point while in use, heat exchange and freeze protection are critical. Water is the most inexpensive and effective heat exchange medium, though it has a relatively narrow temperature range from its freezing point to boiling point. The liquid circulating around the engine absorbs heat created by combustion, then carries it away from the engine where it cools and releases the heat to the environment as it passes through a radiator.Īutomotive coolants are generally made of three main components- water, glycol and an additive or chemical inhibitor package. Vehicle coolants are probably the most commonly known or familiar ones in the spectrum of coolants spanning both industrial and scientific areas.Ĭars and trucks with internal combustion engines burning gasoline, diesel and natural gas fuels use coolants. While a coolant, in general, can be a liquid, or another substance depending upon the application, but our focus is on the engines of the automotive industry. This article attempts to answer most of these and some other questions by breaking things down into bite-size chunks that are easy to understand. With this complexity comes a series of questions ranging from “what’s the difference between a red coolant and a green coolant?” or “what will happen if I mix the two?” to “is ethylene glycol the same as propylene glycol?” Coolants serve relatively simple but important purposes in automotive and industrial applications - corrosion prevention, freeze and boil protection if required.īut in a market of ever-increasing technologies, OEM requirements, and even colors, coolants can seem very complex, maybe even downright vexing. The Workshop Manual is being updated to reflect usage of these antifreeze/coolants.A coolant or an antifreeze as it is commonly referred to, is a liquid that helps regulate the vehicle engine temperatures during operation.
