The full name of coolant is antifreeze coolant, which consists of water, antifreeze, and additives. Based on the antifreeze component, it can be classified into alcohol-based, glycerol-based, and ethylene glycol-based. The functions of coolant are: 1. To prevent the coolant from freezing and cracking the radiator or damaging the engine cylinder block during cold weather; 2. To prevent corrosion of metal parts and aging of rubber components; 3. To reduce the formation of scale, avoiding clogged circulation pipes and impaired cooling system performance; 4. To prevent the engine from overheating, ensuring it operates within the normal temperature range; 5. To provide lubrication for the water pump, thermostat, and other components.
