How to Replace Antifreeze?
1 Answers
Antifreeze replacement method: Before completely replacing the antifreeze, conduct a thorough inspection to check for any signs of leakage or cracks in the pipes, with a focus on the five-way water pipe. The five-way pipe is named for its five connecting interfaces to various parts, and the antifreeze is distributed to different parts of the car through this pipe to function. If there is any antifreeze leakage in this section, replace the water pipe or re-secure the interface as needed. Drain the old antifreeze, then flush the liquid channels with clean water. Add clean water to the antifreeze reservoir, then continuously inject water into the reservoir so that it flows 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 color. Continue injecting clean water until the outflowing water is clear. Note: 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, which allows the antifreeze to flow quickly into the radiator. Then, add another container of antifreeze to 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 it reaches the "MAXT" mark on the reservoir.
