The coolant in your engine plays an important role in keeping it in top condition and protecting its internal components. Water-based coolants are liquids that draw heat from the engine while running through the engine block, then run back out into the radiator, where they are cooled by the air passing over the engine as your vehicle travels along the road.
When the outside temperature drops below zero, the most important thing that engine coolants should include is compounds to prevent them from freezing when they are water-based.
The purpose of most coolants is to maintain the temperature within the engine. To accomplish this, both glycol and antifreeze components are included, however it is also not uncommon to find other components such as corrosion inhibitors and lubricants.
There are so many different kinds of coolant available on the market these days, some are cheap, some are not so cheap; it can be hard to know which one is really good and which one is a waste of money.
So, with this in mind, we have written this article to make it as easy and simple as possible to choose the right coolant, and to recommend the best coolants available on the market at the time of writing.
