How Many Years Can Long-Life Coolant Last?
1 Answers
Long-life coolant can last for five years. Coolant that has exceeded its shelf life may deteriorate, produce impurities, and some of its chemical components may become ineffective, which can affect the cooling system or engine to some extent and should not be used. Coolant replacement method: Before completely replacing the coolant, 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 connections to various parts, and the coolant is distributed to different sections of the car after flowing through it. If there is any leakage of coolant in this section, replace the water pipe or reseal the connections as needed. Drain the old coolant, then flush the fluid channels with clean water. Add clean water to the coolant reservoir, then continuously pour water into the reservoir to allow it to flow through the engine cooling system. 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 clear water flows out. Note: Remember to remove the heater hose and drain the water from the heater core. After draining for about an hour, add the new coolant through the radiator hose to allow it to flow quickly into the radiator. Then, add another bottle of coolant to the reservoir until it is nearly full. Start the engine and let it run for about 10 minutes. As some air is expelled from the cooling system, the coolant level will drop. Add more coolant until it reaches the "MAXT" mark on the reservoir.
