Steps to replace car antifreeze: 1. Unscrew the radiator cap, open the radiator drain valve (usually located at the bottom of the car), and drain the antifreeze; 2. Clean the cooling system by continuously injecting clean water into the engine cooling system. During the flushing process, keep the engine idling to maintain the flow of clean water inside until clear water comes out of the radiator; 3. Stop adding clean water, wait for the water to drain completely, and then close the drain valve; 4. Add new antifreeze until the liquid level is between the max and min water level marks; 5. Close the cap, start the car, and let the engine idle for two to three minutes. The cooling system will expel internal air, causing the antifreeze level to drop slightly. At this point, replenish the antifreeze again.
