Can I Add Engine Coolant by Myself If It's Low?

Engine coolant can be added when it is low. It is appropriate to add coolant when the level is below the standard mark, filling it up to the "MAXT" mark on the reservoir. Coolant is a special additive-containing fluid primarily used in liquid-cooled engine cooling systems. It offers excellent properties such as preventing freezing in winter, boiling in summer, and protecting against scale and corrosion throughout the year. Method for replacing coolant: 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 hose. The five-way hose is named for its five connections to different parts of the engine. Coolant flows through the five-way hose and is distributed to various parts of the car to function. If there is any leakage of coolant in this section, the hose should be replaced or the connections re-secured 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. Initially, the water flowing out of the reservoir may have a faint pink color. Continue adding clean water until the outflow is clear. Note: Remember to remove the heater hose and drain the water from the heater. 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. During this time, the coolant level may drop as air is expelled from the cooling system. Add more coolant until the level reaches the "MAXT" mark on the reservoir.
