How many liters of coolant should be added to the Volkswagen Tiguan L?

The Volkswagen Tiguan L requires 5-6 liters of coolant. Coolant is a liquid containing special additives, primarily used in liquid-cooled engine cooling systems. It offers excellent performance characteristics such as preventing freezing in winter, boiling in summer, and providing year-round protection against scale and corrosion. For the Volkswagen Tiguan, the coolant generally needs to be replaced every 2 years or 40,000 kilometers. However, since driving conditions vary for each vehicle, the replacement interval should be determined based on actual usage. Regularly check the coolant level. If it is found to be insufficient, replenish it promptly. If suspended particles, sediment, or signs of deterioration/discoloration are observed in the coolant, replace it immediately and flush the system. When adding coolant, always use the same brand. Different brands of coolant may have varying production formulas, and mixing them could lead to chemical reactions between additives, rendering them ineffective.
I remember when I used to drive the Tiguan L, changing the coolant was quite a hassle. The manual states it takes about 6 liters, but the actual amount depends on the engine model. The older 1.8T version takes around 5.5 liters, while the newer 2.0T might need close to 7 liters. When I did it myself, I prepared two 4-liter bottles of OEM coolant. First, I drained the old fluid completely, then slowly added the new one, letting the cooling system circulate and vent. Stop adding once it reaches the MAX line in the expansion tank—never overfill it. Also, pay attention to the color; always use the same OEM blue or pink coolant, as mixing different colors can cause scaling. If you take it to a shop, the mechanic will use a pressure tank to fill it precisely in one go. If you're doing it yourself, it's best to have some distilled water on hand for dilution. Replacing it every two years is the safest bet—don't wait until the level drops below the MIN line.
