How often should the coolant be changed in a Volkswagen Tiguan?

[ValeriaMarie]

Volkswagen Tiguan's coolant should be changed every two years or 40,000 kilometers. The replacement method is as follows: 1. Park the vehicle for a period of time, then unscrew the drain valve at the bottom of the radiator to completely drain the old coolant; 2. Keep the car idling while continuously adding clean water to the coolant reservoir until the discharged water runs clear; 3. Fill the reservoir with new coolant, ensuring the liquid level remains between the MAX and MIN marks. Taking the 2021 Tiguan X 2WD Yuexiang Edition as an example, it is equipped with a 2.0T turbocharged engine, delivering a maximum horsepower of 186 PS, maximum power of 137 kW, and maximum torque of 320 Nm, paired with a 7-speed dual-clutch transmission.
