2. Facing the front of the car, use a vise to open the drain valve counterclockwise. It is recommended to drain the water when the car is cold to avoid burning your hands.
3. There is a drain screw on the beam below the water tank. Simply unscrew it and the water will flow out. Remove the old water tank after emptying it.
4. Install a new auxiliary water tank. The length of the pipe head is the same as the pipe diameter and corresponds directly.
