Does a car need antifreeze?

Yes, a car needs antifreeze, and it is essential to use the same brand of antifreeze when adding it. Different brands of antifreeze may have varying production formulas, and if mixed, multiple additives could undergo chemical reactions, rendering them ineffective. The method for replacing antifreeze is as follows: Before completely replacing the antifreeze, conduct a thorough inspection to check for any signs of leakage or cracks in the pipelines, with a particular focus on the five-way water pipe. Antifreeze flows through the five-way pipe and is then distributed to different parts of the car to function. If there is any leakage of antifreeze in this section, the water pipe should be replaced or the connection re-secured as needed. Drain the old antifreeze, then flush the liquid channels with clean water. Add clean water to the antifreeze reservoir, then continue to pour water into the reservoir to allow it to flow continuously through the engine cooling system. Start the engine and let it idle for 3 to 5 minutes to circulate the water. The water initially flowing out of the reservoir will have a faint pink color. Continue adding clean water until the water coming out is clear. Note: Do not forget to remove the heater hose and drain the water from the heater core. After draining for about an hour, add the new antifreeze through the radiator hose. Then, pour another bottle of antifreeze into the antifreeze reservoir until it is nearly full. Start the engine and let it run for about 10 minutes. At this point, the coolant level will drop slightly as air is expelled from the cooling system. Add more antifreeze until the reservoir reaches the maximum mark "MAXT."
