Difficulty: Advanced · About 150 min · Nissan Maxima

Replace the windshield washer reservoir on a 1994–2003 Nissan Maxima by draining fluid, removing the bumper cover, transferring the pump and sensor, and testing for leaks.

Steps

1. Remove the front bumper cover

   Release the upper and lower bumper clips and remove the lower screws. Pull back both inner fenders, remove their mounting bolts, and carefully release the side marker lamps and bumper edges.

2. Disconnect the bumper wiring

   Support the cover as it moves forward and unplug any fog lamp connectors. Set the cover on a protected surface to avoid scratching it.

3. Drain and remove the reservoir

   Place a drain pan below the washer system, unplug the pump and secure the hoses, then allow the fluid to drain. Disconnect the fill neck, hose retainers, reservoir mounting bolts, and fluid level sensor before removing the tank.

4. Install the replacement reservoir

   Position the new tank on its bracket and install its mounting bolts. Reconnect the level sensor, washer pump, hoses, and fill neck, ensuring each fitting is fully seated.

5. Refill and test the washer system

   Fill the reservoir with suitable washer fluid using a funnel. Turn the ignition on and operate the washers, checking spray function and inspecting the pump and hose connections for leaks.

6. Reinstall the bumper cover

   Reconnect fog lamp wiring and align the bumper cover with its guides. Refit the wheel well bolts, side markers, splash shield, and upper and lower clips and screws.

Check your vehicle’s repair manual for exact specifications and fit.
