What is the method for using car antifreeze?

[MacEmilio]

The method for using car antifreeze is: 1. Use the same brand of antifreeze; 2. Avoid mixing with water. The steps for replacing antifreeze are: 1. Open the vehicle's engine hood, and the antifreeze reservoir can be seen in the upper right corner; 2. Open the antifreeze plug under the radiator to drain the old antifreeze; 3. Add new antifreeze, tighten the cap, and the antifreeze replacement is complete. The functions of antifreeze are: 1. To provide anti-corrosion protection for the engine's cooling system; 2. To prevent water from boiling when the engine temperature reaches 100 degrees Celsius; 3. To prevent scale formation and avoid reducing the radiator's cooling effect; 4. To ensure the engine operates normally under low temperatures.
