Can I Add More Antifreeze If It's Low?

[SamuelLee]

You can add more antifreeze if the level is low. It is appropriate to add antifreeze when the level is below the standard mark, filling up to the "MAXT" line on the reservoir. Antifreeze is a coolant containing special additives, primarily used in liquid-cooled engine cooling systems. It offers excellent performance in preventing freezing in winter, boiling in summer, and protecting against scale and corrosion year-round. Method for replacing antifreeze: Before completely replacing the antifreeze, conduct a thorough inspection to check for any leaks or cracks in the pipes, with a focus on the five-way hose. The five-way hose is named for its five connection points that distribute antifreeze to different parts of the car. If there are signs of antifreeze leakage in this area, replace the hose or reseal the connections as needed. After draining for about an hour, add the new antifreeze through the radiator hose to allow it to flow quickly into the radiator. Then, fill the antifreeze reservoir with another bottle until it is nearly full. Start the engine and let it run for about 10 minutes. As the cooling system expels some air, the fluid level will drop. Add more antifreeze until the reservoir reaches the "MAXT" mark. Drain the old antifreeze and flush the channels with clean water. Fill the antifreeze reservoir with water and let it circulate through the engine cooling system. Idle the engine for 3 to 5 minutes to allow the water to circulate. Initially, the water draining out will have a faint pink tint. Continue flushing with clean water until the outflow is clear. Remember to disconnect the heater hose and drain the water from the heater system.
