1 Answers
The methods to handle when the coolant light comes on are: 1. Pull over immediately and turn off the engine as soon as possible; 2. After the engine cools down, open the front hood to inspect; 3. Visit a 4S store promptly to have professionals add coolant. Coolant, short for antifreeze coolant, is composed of water, antifreeze, and additives. Based on the antifreeze component, it can be categorized into alcohol-based, glycerol-based, and ethylene glycol-based. The functions of coolant are: 1. To prevent the coolant from freezing and expanding in cold seasons, which could crack the radiator and damage the engine cylinder block; 2. To prevent corrosion of metal parts and aging of rubber components; 3. To reduce scale formation, avoiding clogging of circulation pipes and affecting the cooling system's heat dissipation function; 4. To prevent the engine water temperature from becoming too high, ensuring the engine operates at the proper working temperature; 5. To provide lubrication for the water pump thermostat and other components.
