Difficulty: Intermediate · About 35 min · Toyota Tundra

Replace the windshield-washer level sensor on a 2014–2019 Toyota Tundra by removing the reservoir and renewing the sensor grommet.

Steps

1. Drain and remove the reservoir

   Switch off the ignition and place a container under the washer bottle. Disconnect the pump and level-sensor plugs, remove the reservoir fasteners, lift the bottle out, and drain its fluid.

2. Remove the old sensor

   Disconnect the washer hose and move the reservoir to a clean work surface. Release the level sensor from its grommet and remove the old seal without scratching the bottle opening.

3. Fit the replacement sensor

   Install a compatible new grommet in the reservoir and press the sensor into it until seated. Reconnect the hose and make sure the sensor is oriented correctly.

4. Reinstall the bottle

   Lower the reservoir into its original mounts and secure its fasteners. Reconnect the pump and sensor wiring plugs, then route the hose through its retaining clips.

5. Refill and verify

   Fill the washer bottle with suitable fluid and check the sensor warning and washer operation. Inspect the grommet and hose connections for leaks before reinstalling any trim.

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