The function of antifreeze
When parking in cold winter, antifreeze can prevent the coolant from freezing, cracking the radiator and freezing the engine cover or body. Antifreeze can be used not only in winter, but also all year round. The first function of coolant is to prevent corrosion. Most cars are made of metals, including copper, iron, aluminum and steel. You know, these metals will corrode and rust when exposed to water for a long time at high temperature.
At this time, the function of antifreeze is obvious, which not only will not corrode the cooling system of the engine, but also has the function of corrosion prevention and rust prevention. Secondly, the boiling point of water is 100℃, and the boiling point of high-quality antifreeze is usually above 1 10℃, so it will prevent water from boiling when used in summer.
