Do New Cars Need to Replace Antifreeze?
1 Answers
New cars do not need to replace antifreeze as they come with factory-installed antifreeze, which is of high quality and will not cause issues like overheating or cracking. Typically, antifreeze should be replaced every two years or every 30,000 kilometers. The method for replacing antifreeze 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 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 leakage of antifreeze in this area, replace the hose or resecure the connection as needed. Drain the old antifreeze, then flush the liquid channels with clean water. Add clean water to the antifreeze reservoir and continue to pour water into the reservoir, allowing it to flow continuously through the engine cooling system. Then, start the engine and let it idle for 3 to 5 minutes to circulate the water. The water initially flowing out of the reservoir will have a faint pink color. Continue adding clean water until the water flowing out 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. 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 slightly as air is expelled from the cooling system. Add more antifreeze until the level reaches the "MAXT" mark on the reservoir.
