How do you change the windshield water reservoir from a Peugeot 307?

To change the windshield washer reservoir on a Peugeot 307, first, disconnect the negative battery terminal for safety. Remove any necessary components, such as the front bumper or wheel arch liner, to access the reservoir. Disconnect the washer fluid hoses and electrical connectors, then unbolt the reservoir from its mounting points. Replace it with the new reservoir, reattach the hoses and connectors, and finally reassemble any removed components.
