What is the appropriate level to add coolant to a Nissan Sylphy?

[Shawn]

The coolant in a Nissan Sylphy should be added to the middle position between the upper mark (MAX) and the lower mark (MIN) on the reservoir. 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 a focus on the five-way water pipe. The coolant flows through the five-way pipe and is then distributed to different parts of the car to function. If there is any leakage of coolant in this section, the water pipe should be replaced or the interface re-secured as needed. Drain the old coolant, then flush the liquid channels with clean water. Add clean water to the coolant reservoir, then continuously inject water into the reservoir so that it flows 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 be slightly pinkish. Continue adding clean water until the water coming out is clear. Note: Remember to disconnect 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. Then, add another bottle of coolant to the coolant reservoir until it is nearly full. Start the engine and let it run for about 10 minutes. At this point, the coolant level will drop slightly as air is expelled from the cooling system. Add more coolant until it reaches the maximum mark "MAXT" on the reservoir.
