Do Cars Need Antifreeze?
1 Answers
Cars do need antifreeze. Antifreeze is a type of 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 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 pipes, with a special focus on the five-way hose. Antifreeze is distributed to different parts of the car to function after flowing through the five-way hose. If there is any leakage of antifreeze in this part, replace the hose or resecure the connection as needed. Drain the old antifreeze and then flush the liquid channels with clean water. Add clean water to the antifreeze reservoir and continue to fill it until the 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 flowing out of the reservoir may have a faint pink color. Keep adding clean water until the water coming out is clear. Remember 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. As some air is expelled from the cooling system, the fluid level will drop. Add more antifreeze until it reaches the maximum mark "MAXT" on the reservoir.
