To fit a new washer pump in an Astra MK4, start by disconnecting the negative battery terminal for safety. Remove the washer fluid reservoir by unscrewing any retaining screws and disconnecting the hoses. Take out the old pump, usually located at the bottom of the reservoir, and replace it with the new pump, ensuring it's securely fitted. Finally, reassemble the reservoir, reconnect the hoses, and reconnect the battery before testing the pump.
