Removing the power steering reservoir in a Ford focus 2 car

The hydraulic booster reservoir is located in the engine compartment on the right and is mounted through a bracket on the generator.
We remove the power steering reservoir for replacement if it is damaged.
With a syringe or a rubber pear, we pump out the working fluid from the tank.

With the “8” head, we unscrew the bolt securing the tank to the bracket ...

... and remove the bolt.
We substitute a container under the tank to collect the remaining liquid.

Raise the tank.

Squeezing the ends of the clamp that secures the filling line hose to the tank nozzle with pliers, move the clamp and remove the hose.
Similarly, remove the drain hose from the other pipe.
Install the new tank in reverse order.
