How to Know If the Antifreeze Is Low?
1 Answers
Methods to know if the antifreeze is low: 1. Check the antifreeze warning light on the dashboard—if it lights up, it likely indicates a lack of antifreeze; 2. Open the engine hood directly to inspect the antifreeze reservoir. If the fluid level is below the MIN mark, do not continue driving. It is necessary to add antifreeze promptly at this time. Automotive antifreeze ensures the car can still operate during low winter temperatures. Engine coolant contains substances that lower the freezing point of water, acting as antifreeze to prevent the cooling system from freezing in cold weather. The components of automotive antifreeze include: inorganic substances like calcium chloride, and organic substances such as methanol, ethanol, ethylene glycol, glycerol, lubricating oil, and purified water.
