What is the method for replacing the coolant in the Tiguan?

The method for replacing the coolant in the Tiguan is: 1. Open the car hood after the engine has cooled down; 2. Open the coolant reservoir cap; 3. Lift the vehicle and open the radiator drain plug, drain the old coolant, and then reinstall the drain plug; 4. Lower the vehicle and pour new coolant into the coolant reservoir. The Tiguan is a compact SUV with body dimensions of 4506mm in length, 1809mm in width, and 1685mm in height, with a wheelbase of 2684mm and a fuel tank capacity of 63 liters. It is equipped with a 1.8T turbocharged engine, delivering a maximum horsepower of 160PS and a maximum power of 118kW, with the maximum power achieved at 4500 to 6200 rpm. It is paired with a 6-speed automatic transmission.
I've changed the coolant myself several times and found it quite interesting. Let me share my experience with the Tiguan. First, wait until the engine is completely cooled – ideally leave it overnight or for several hours, otherwise the hot liquid could spray out and cause burns. Then place a basin under the car, locate the drain plug or hose at the bottom of the radiator or engine block, and use a wrench to loosen it to drain the old fluid. You might see rusty water or sediment coming out – be patient and let it all drain completely. If necessary, flush the system with a hose to remove any debris. Before adding new coolant, mix it according to the instructions – the Volkswagen Tiguan typically uses G12 or G13 coolant, mixed at a 50% coolant to 50% distilled water ratio. Fill the radiator, start the engine, let it warm up, and run the heater at maximum for a few minutes to purge air bubbles. Top up to the MAX line and check for leaks. The whole process takes less than an hour, requiring just a wrench, basin, and gloves, saving you hundreds in labor costs. Remember never to mix different types of coolant as this can corrode the engine. Changing it annually maintains cooling system efficiency and prevents overheating issues.
