Where is the coolant drain hole located on the Boyue?

The coolant drain hole on the Boyue is located at the lower part of the car's radiator. How to replace the coolant: Before completely replacing the coolant, conduct a thorough inspection first to check for any signs of leakage or cracks in the pipes, with a particular focus on the five-way hose. The five-way hose is named for its five connections to various parts, and the coolant flows through it before being distributed to different sections of the car to perform its function. If there are signs of coolant leakage in this part, 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, then continue to pour water into the reservoir so that it flows 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 flowing out of the reservoir will have a faint pink tint. Continue adding clean water until clear water flows out. Note: Don’t forget to remove the heater hose and drain all the water from the heater core. After draining for about an hour, add the new coolant through the radiator hose—this is the quickest way to get the coolant 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 slightly. Add more coolant until it reaches the "MAXT" mark on the reservoir.
The coolant drain hole of the Boyue is located at the bottom right of the radiator, which is a plastic twist valve. I discovered this when I changed the coolant myself last time. First, wait for the engine to completely cool down, put on gloves, and open the hood. Follow the pipe from the auxiliary tank downwards, and you'll find it in the bottom corner of the radiator—a black plastic head about the size of a green bean. Before unscrewing it, prepare a water-catching pan, as the sudden flow can splash everywhere. After refilling with new coolant, remember to let the engine idle for ten minutes and observe if there are any abnormal fluctuations on the dashboard's temperature gauge. Finally, check for leaks at the pipe connections. I forgot this step last time and found pink water stains on the ground the next day.
