1.When selecting antifreeze, check the following points: check whether the factory name, address, registered trademark, and execution standards are complete; Check if the weight of the antifreeze solution matches the packaging quality; Check if the freezing and boiling points of the antifreeze are compatible with the minimum temperature in the driving area of your vehicle; Check if the antifreeze tank has sediment and layering.

2.In addition, it also depends on the antifreeze effect. Ordinary antifreeze can reach -40 ℃, while high-quality antifreeze should reach around -60 ℃, which is an important indicator for calibrating the quality of antifreeze; The other is the boiling point of antifreeze. The boiling point of water is 100 ℃, while the antifreeze should be at least above 108 ℃. That is to say, the lower the freezing point, the higher the boiling point, and the greater the temperature difference. Relatively speaking, the better the quality of antifreeze.
