Do New Cars Need Antifreeze?
1 Answers
New cars do not require additional antifreeze. Since new vehicles come with factory-installed antifreeze, it is generally sufficient to replace the antifreeze 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 particular attention to 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 fluid channels with clean water. Add clean water to the antifreeze reservoir and continue to fill it until 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 draining from the reservoir will have a faint pink tint. Continue adding clean water until the water coming 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 container 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 cooling system. Add more antifreeze until the level reaches the "MAXT" mark on the reservoir.
