How do you replace a windscreen bottle on a peugeot 308?

To replace the windscreen washer bottle on a Peugeot 308, first, ensure the vehicle is turned off and disconnect the battery for safety. Locate the washer bottle, which is typically found in the engine bay; remove any covers if necessary. Disconnect the hoses and electrical connectors from the old bottle, then unbolt or unclip it from its mounting. Install the new bottle by reversing the process, reconnecting the hoses and electrical components, and finally refilling it with washer fluid.
