How Often Should the Coolant Be Replaced in a New Car?
1 Answers
New cars typically require coolant replacement every two years or every 30,000 kilometers. To prevent excessive foaming, which can reduce the heat exchange efficiency between the coolant and engine components, ensure the product is within its validity period when adding it. Long-life coolants can have a validity period of up to three years. If suspended particles, sediment, or signs of deterioration or discoloration are found in the coolant, it should be replaced promptly, and the system should be cleaned. The method for replacing coolant is as follows: Before completely replacing the coolant, conduct a thorough inspection to check for any signs of leakage or cracks in the pipes, with particular attention to the five-way hose. The coolant is distributed to different parts of the car through the five-way hose to perform its function. If there is any leakage of coolant in this section, replace the hose or resecure the connection as needed. Drain the old coolant, then flush the fluid channels with clean water. Add clean water to the coolant reservoir, then continue to pour water into the reservoir to allow it to flow continuously through the engine cooling system. Start the engine and let it idle for 3 to 5 minutes to circulate the water. The water initially draining from the reservoir may have a faint pink color. Continue adding clean water until the water coming out is clear. Remember to remove the heater hose and drain the water from the heater core. Approximately one hour after draining, add the new coolant through the radiator hose. Then, add another container of coolant to the coolant 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 purged from the system. Add more coolant until it reaches the "MAX" mark on the reservoir.
