What is the method for replacing car antifreeze?
1 Answers
The method for replacing car antifreeze is: 1. Unscrew the radiator cap, open the radiator drain valve, 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 circulation of the clean water inside until clean water flows out from the radiator; 3. Stop injecting clean water, wait for the clean water to drain completely, then close the drain valve; 4. Add new antifreeze until the liquid level is between the max and min 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, additional antifreeze should be added.
