The full name of antifreeze is "antifreeze coolant", as the name suggests, antifreeze has two main functions: antifreeze and cooling. Antifreeze function is mainly reflected in winter - to prevent the car in winter parking, antifreeze caused by ice tank, engine cylinder swelling and cracking.
As the working medium in the engine cooling system, antifreeze will also take away the excess heat generated in the engine work and transfer to the air. When the antifreeze is insufficient, the engine operating temperature will rise. At this time, if the vehicle continues to drive with high load, it will lead to the damage of the piston, connecting rod and other parts of the engine, and the whole engine will be scrapped.
In addition, the metal parts in the cooling system are prone to electrochemical corrosion in the liquid environment, the corrosion products may block the pipeline, cause engine overheating or even paralysis, so high-quality antifreeze has anti-corrosion function. In addition, qualified antifreeze also needs to have the function of preventing scale, so as to reduce the generation of scale, so as not to block the circulation pipe and affect the cooling function of the cooling system.
