How Long Does It Take to Replace Antifreeze?

[EstherAnn]

Antifreeze should be replaced every two years or 40,000 kilometers. The method for replacing antifreeze in a car is as follows: 1. Wait for the engine to cool down and then open the car hood; 2. Open the antifreeze reservoir cap; 3. Lift the vehicle and open the radiator drain plug, drain the old antifreeze, and then reinstall the drain plug; 4. Lower the vehicle and pour new antifreeze into the antifreeze reservoir. The functions of antifreeze are: 1. To provide anti-corrosion protection for the engine's cooling system; 2. To prevent the engine water from boiling when the temperature reaches 100 degrees Celsius; 3. To prevent the formation of scale, avoiding reduced heat dissipation in the radiator; 4. To ensure the engine operates normally under low-temperature conditions.
