What to Do When Coolant Is Mixed?

[CarterLee]

The solution when coolant is mixed is: completely drain the coolant from the radiator, flush it thoroughly with purified water, and then refill it with new coolant. The functions of coolant are: 1. Prevent the coolant from freezing and cracking the radiator or damaging the engine cylinder block during cold weather parking; 2. Prevent corrosion of metal components and aging of rubber parts; 3. Reduce the formation of scale to avoid clogging the circulation pipes and affecting the cooling system's heat dissipation function; 4. Prevent the engine from overheating, ensuring it operates at the proper working temperature; 5. Provide lubrication for the water pump, thermostat, and other components. Coolant is also known as antifreeze. As part of regular car maintenance, the engine antifreeze should be replaced once a year.
