Where is the BMW x 1 water tank?

The BMW x 1 water tank is on the left side of the engine. The way to exhaust the BMW x 1 water tank is to change the antifreeze, turn on the vehicle ignition switch to the second gear, turn on the vehicle warm air, adjust the temperature to the highest, then adjust the air volume to the minimum, and then step on the accelerator 15 seconds to start the exhaust. The replacement method of antifreeze is as follows: 1, unscrew the water tank cover, remove the water pipe of the water tank, and release antifreeze; 2. Insert the rubber hose connected with the tap water pipe into the water inlet of the water tank, and turn on the tap water to make it continuously flow through the engine cooling system; 3. During the flushing operation, let the engine run at idle speed and keep the above operation until the water tank releases clean water. Turn off the tap water, and then turn off the drain valve of the water tank after all the water in the cooling system is drained; 4. Add antifreeze from the water inlet of the water tank, and add antifreeze to the water tank. Unscrew the cover of the liquid storage tank, add antifreeze, and reach the "Max" scale line, and be careful not to exceed the "Max" scale line. Cover the water tank cover and the liquid storage tank cover and tighten them; 5, start the engine, idle running for 2 ~ 3 minutes, unscrew the water tank cover. At this time, because some air is excluded from the cooling system, the liquid level of antifreeze will be reduced. At this time, antifreeze should be supplemented to make antifreeze reach the "Max" scale. Cover the water tank.
