BYD Song coolant replacement tutorial: 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 coolant leakage in this area, replace the hose or resecure the connections as needed. Drain the old coolant, then flush the liquid channels with clean water. Add clean water to the coolant reservoir and continue filling until water flows 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 coming out will have a faint pink tint. Keep adding clean water until the outflow is clear. Remember to disconnect the heater hose to drain the water from the heater core. After about an hour of draining, add the new coolant through the radiator hose for quick flow into the radiator. Then, fill the coolant reservoir with another bottle of coolant 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. Top it up to the "MAXT" mark on the reservoir. Can different coolants be mixed? Always use the same brand of coolant. Different brands may have varying formulations, and mixing them could cause chemical reactions between additives, rendering them ineffective.
