Steps
Remove the washer reservoir
Switch the ignition off, disconnect the pump connectors, and unclip the hoses and wiring. Remove the reservoir bolts and lift the tank out without stressing nearby lines.
Drain and transfer the pumps
Place the reservoir in a catch pan and disconnect the washer hoses. Let remaining fluid drain, then remove the pumps and inspect their seals.
Install pumps and reservoir
Fit sound or replacement pump seals and press each pump into its opening. Reconnect the hoses and plugs, route the wiring as before, and secure the reservoir with its bolts.
Refill and test washers
Add washer fluid to the correct level and operate each washer circuit. Check pump seals and hose connections for leaks and confirm spray reaches the glass.
Check your vehicle’s repair manual for exact specifications and fit.
