How Much Antifreeze Should Be Added to a Car at One Time?
1 Answers
A car typically requires 5 to 6 liters of antifreeze at one time. Antifreeze is a special additive-containing coolant primarily used in liquid-cooled engine cooling systems. It offers excellent performance in preventing freezing in winter, boiling in summer, and resisting scale and corrosion throughout the year. How to Replace Antifreeze: Before completely replacing the antifreeze, conduct a thorough inspection to check for any signs of leakage or cracks in the pipelines, with a focus on the five-way hose. Antifreeze flows through the five-way hose and is then distributed to different parts of the car to function. If there is any antifreeze leakage in this section, replace the hose or resecure the connection as needed. Drain the old antifreeze, then flush the liquid channels with clean water. Add water to the antifreeze reservoir and continue filling it until clean water flows continuously through the engine cooling system. Start the engine and let it idle for 3 to 5 minutes to circulate the water. Initially, the water flowing out of the reservoir may have a faint pink tint. Keep adding clean water until the outflow is clear. Remember to remove the heater hose and drain the water from the heater core. After about an hour of draining, add the new antifreeze through the radiator hose. Then, pour another container of antifreeze into the antifreeze reservoir until it is nearly full. Start the engine and let it run for about 10 minutes. During this time, the coolant level may drop as air is expelled from the cooling system. Top up the antifreeze to the "MAXT" mark on the reservoir.
