How to Replace Coolant in Volkswagen Tiguan?

[AlessandraFitz]

Volkswagen Tiguan coolant replacement method is: 1. Let the vehicle stand for half an hour, then unscrew the drain screw at the bottom of the radiator. When no more coolant flows from the drain outlet, the old coolant is basically drained; 2. Keep the vehicle idling while continuously adding clean water to the coolant reservoir; 3. After the water stops dripping, tighten the drain valve and turn off the engine. Pour new coolant into the reservoir, ensuring the fluid level is between the MAX and MIN marks; 4. Start the engine again and let it idle to further expel air from the cooling system pipes. The coolant level will drop slightly; 5. Once the level stabilizes, top up the coolant to between MIN and MAX marks.
