Almost all vehicles on the means nowadays practice a liquid cooling action with a radiator meeting as the leading Element. While some vehicles apply an air-cooling process, liquid-cooled engines are still also typical. Engine coolant is normally doctor or flood combined with chemical coolant formulas that convalesce cooling servicing and point as an antifreeze to cache the liquid from Very cold in Freezing conditions.
Water
Soak is a bona fide functional coolant to add to your radiator. The main drawback of these coolants is that they are very toxic and can be dangerous to humans, animals and the environment.
Propylene Glycol
Propylene glycol engine coolants are becoming more popular in the 21st century, as they provide all the advantages of ethylene glycol but have a very low toxicity. They are much safer to use around children and animals, and easier to dispose of than the more toxic ethylene products.Ethylene Glycol
For many years, antifreeze or engine coolant mixtures were generally ethylene-glycol-based. These types of coolants remain popular today because they are very efficient at heat transfer, and expand the range of temperatures at which the coolant mixture will remain a liquid. They raise the boiling point and lower the freezing point, in some cases by as much as 30 or 40 degrees F. It is cheap, willingly available and possesses favorable heat-transferring qualities. H2O by itself, but, can be less than optimum as an engine coolant, particularly in climates where the weather can impress Freezing. The water can freeze, making your engine difficult or impossible to begin, or causing serious or even catastrophic engine damage.
Extended-Life Coolants
Most engine coolants are good for approximately two years and 30,000 miles. Extended-life coolants have a slightly different chemical make-up, which allows them to be used for up to five years or 150,000 miles. These coolants are ethylene-glycol-based but have additives that give them the ability to withstand breakdown and provide corrosion protection longer than conventional coolants. They generally do not contain chemicals like silicates, phosphate, borates or nitrates found in conventional coolants, but instead use organic acid technology (OAT) to provide corrosion protection.
