The full name of antifreeze should be called antifreeze coolant, which means coolant with antifreeze function. Antifreeze can prevent the coolant from freezing and cracking the radiator and freezing the engine cylinder block or head during cold winter parking.
Many people think that antifreeze is only used in winter, but in fact, antifreeze is used all year round.
Antifreeze is a kind of coolant containing special additives. It is mainly used in liquid-cooled engine cooling systems. Antifreeze has excellent properties such as antifreeze in winter, antiboiling in summer, antiscale and anticorrosion all year round. At present, more than 95% of water-based antifreeze using ethylene glycol at home and abroad uses ethylene glycol. Compared with tap water, the most significant feature of ethylene glycol is antifreeze, while water cannot prevent freezing. Secondly, ethylene glycol has a high boiling point, low volatility, moderate viscosity, small change with temperature, and good thermal stability. Therefore, glycol-based antifreeze is an ideal coolant.
