How to Replace Vehicle Antifreeze?
1 Answers
Vehicle antifreeze replacement method is as follows: Before completely replacing the antifreeze, conduct a thorough inspection to check for any signs of leakage or cracks in the pipes, with a particular focus on the five-way water pipe. The five-way pipe is named for its five connections to various parts, and the antifreeze is distributed to different sections of the car through this pipe to function. If there is any antifreeze leakage in this part, replace the water pipe or re-secure the connections as needed. Drain the old antifreeze, then flush the liquid channels with clean water. Add clean water to the antifreeze reservoir, then continue to pour water into the reservoir to allow it to circulate continuously through the engine cooling system. Start the engine and let it idle for 3 to 5 minutes to ensure the water circulates. Initially, the water flowing out of the reservoir may have a slight pink tint. Continue adding clean water until the outflow 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 to allow it to flow quickly into the radiator. Then, add another bottle of antifreeze to 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 will drop as air is expelled from the system. Top up the antifreeze to the "MAXT" mark on the reservoir.
