All coolant from the cooling system must be leaked before operation. After that, you need to loosen the upper hoses and remove them from the bacht with the help of pliers. Now we need to lift and tilt the tank in the direction of the car's headlights so that it's out of the cordon. Then we need the passengers to looser the lower handle and remove the hose from the tube. Then we can take off the tank. Remember that the manufacturer recommends replacing the expansion chiller with a cork once a year.
