What is the method for changing coolant in the Tiguan?
3 Answers
The method for changing coolant in the Tiguan is: After the engine has cooled down, open the car hood, locate and open the coolant reservoir, lift the vehicle, open the radiator drain plug, drain all the old coolant, then reinstall the drain plug, lower the vehicle, pour a certain amount of coolant into the reservoir, and run the engine to fill the coolant between the MAX and MIN marks on the reservoir. The Tiguan is a compact 5-door, 5-seat SUV with dimensions of 4506mm in length, 1809mm in width, and 1685mm in height, and a wheelbase of 2684mm. The Tiguan is equipped with a 1.8T turbocharged engine and a 6-speed automatic transmission, delivering a maximum power of 118 kW and a maximum torque of 250 Nm.
Changing the coolant in a Tiguan is actually quite simple, the key is not to burn yourself. It's best to wait a few hours after the engine is turned off and cooled down before starting, as a hot engine can spray steam and cause injury. First, locate the expansion tank cap of the cooling system and slowly unscrew it to release pressure. Find the drain screw or hose underneath, prepare a large container to catch the old fluid, and remember that the old fluid is toxic and should not be poured randomly. After draining completely, if the radiator is dirty, you can rinse it with water, but not for too long. Then add new coolant to the recommended level, neither too much nor too little. Start the engine and let it run for a few minutes to allow the system to vent, then turn it off after the fan starts and check the fluid level to top it up. The whole process requires gloves and goggles, with just a wrench and funnel as tools. Changing it every two years can protect the engine from rust or overheating failures. If the Tiguan has an electric pump, be careful not to get the wires wet. Finally, make sure there are no leaks, and even beginners can handle it, saving unnecessary expenses at the shop.
I've changed the coolant in my Tiguan, so let me share my experience. First, pick a nice day to work on it, park the car on level ground, and wait for the engine to cool down—don't rush. Open the hood, locate the expansion tank cap, and slowly unscrew it by hand—there might be pressure inside. Use a wrench to loosen the drain plug at the bottom of the car, and place a bucket underneath to catch the old coolant. If the fluid looks cloudy, it's definitely time for a change. After draining, tighten the drain plug and pour new coolant through the cap opening—don't overfill, just up to the MAX line. Start the engine and let it run for about ten minutes, then turn it off and check the coolant level, topping up if needed. The key is to avoid air pockets, as they can cause overheating. I used the factory-recommended blue coolant, mixed with a bit of water at a 1:1 ratio. The whole process took less than half an hour, and the tools required were just a few basics—doing it yourself can save you a few hundred bucks. Change it every two years regularly, and your car will run smoother.
