To what level should the coolant be filled in the Volkswagen Tiguan?

Volkswagen Tiguan coolant should be filled up to the "MAXT" mark on the reservoir. Coolant replacement method: Before completely replacing the coolant, conduct a thorough inspection to check for any signs of leakage or cracks in the pipelines, with special attention to the five-way hose. The five-way hose is named for its five connecting interfaces to various parts. The coolant flows through the five-way hose and is then distributed to different parts of the car to function. If there is any coolant leakage in this part, replace the hose or re-secure the interface as needed. Drain the old coolant, then flush the liquid channels with clean water. Add clean water to the coolant reservoir, then continue adding water to ensure it continuously flows 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 will be slightly pinkish. Continue adding clean water until the outflowing water is clear. 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—this allows the coolant to flow quickly into the radiator. Then, add another container of coolant to the reservoir until it is nearly full. Start the engine and let it run for about 10 minutes. As the cooling system expels some air, the coolant level will drop slightly. Top up the coolant again until it reaches the "MAXT" mark on the reservoir.
