Can You Add More Antifreeze If It's Low?

[VonKaylee]

You can add more antifreeze if the level is low. It is appropriate to add antifreeze when it falls below the standard level, filling it up to the "MAXT" mark 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 signs of leaks or cracks in the pipes, with a focus on the five-way hose. The five-way hose gets its name from having five connection points to various parts of the vehicle. Antifreeze flows through this hose and is distributed to different sections of the car to perform its function. If there is any leakage of antifreeze in this area, the hose should be replaced or the connections re-secured as needed. Drain the old antifreeze and then flush the fluid channels with clean water. Add water to the antifreeze reservoir and continue filling it until clean water flows continuously through the engine cooling system. Then, start the engine and let it idle for 3 to 5 minutes to circulate the water. Initially, the water draining from the reservoir may appear slightly pinkish. Continue adding clean water until the outflow is clear. Note: Remember to remove the heater hose to drain all the water from the heater system. After draining for about an hour, add the new antifreeze through the radiator hose—this allows the antifreeze to flow quickly into the radiator. Next, pour another container of antifreeze into the reservoir until it is nearly full. Start the engine and let it run for about 10 minutes. As some air is expelled from the cooling system, the fluid level will drop slightly. Top up the antifreeze again until it reaches the "MAXT" mark on the reservoir.
