Preparation

Procedure
- 1Access the washer reservoirOpen the hood and locate the washer reservoir on the driver's side of the engine compartment, mounted to the inner fender. Remove any engine covers if equipped that may restrict access to the reservoir mounting area.
- 2Disconnect the washer pump electrical connectorLocate the electrical connector on the washer pump motor at the bottom of the reservoir. Press the release tab and pull the connector straight off the pump. Do not pull on the wires themselves.
- 3Disconnect the washer hoseLocate the washer fluid hose connection at the pump outlet. Gently squeeze the hose clamp or use a flathead screwdriver to release it, then pull the hose off the pump nipple. Expect residual fluid to drain from the hose.
- 4Remove the reservoir mounting boltsLocate and remove the two 10mm mounting bolts securing the reservoir to the inner fender well. On some models, one bolt is at the top and one at the bottom of the reservoir bracket.Torque specModule Mounting Bolts8 Nm (6 lb-ft)
- 5Remove the reservoir assemblyCarefully lift the reservoir upward and out of the engine compartment. Tilt it to drain any remaining washer fluid into your drain pan. Be mindful of the pump motor still attached to the bottom of the reservoir.
- 6Transfer the washer pump (if reusing)If the pump is functioning properly and only the reservoir needs replacement, remove the pump from the old reservoir. Rotate the pump counterclockwise while pulling down to release it from the reservoir grommet. Inspect the grommet for damage and replace if cracked or torn.
- 7Install pump into new reservoirInsert the new or existing grommet into the reservoir pump opening if not pre-installed. Lubricate the pump body lightly with soapy water if needed. Push the pump firmly into the grommet while rotating clockwise until it locks into place. Ensure the pump is fully seated and the grommet seals properly.
- 8Install the new reservoirPosition the new reservoir into the mounting location in the inner fender well. Align the mounting holes and hand-thread the two mounting bolts. Tighten the bolts evenly to specification.Torque specModule Mounting Bolts8 Nm (6 lb-ft)
- 9Reconnect washer hose and electrical connectorPush the washer fluid hose firmly onto the pump outlet nipple until it seats completely. Reinstall or reposition the hose clamp if equipped. Reconnect the electrical connector to the pump motor until it clicks into place.
- 10Fill and test the systemFill the new reservoir with windshield washer fluid to the full line (approximately 3.5 quarts capacity). Turn the ignition to ON position (do not start engine) and activate the washer system. Check for leaks at all connections and verify proper spray pattern from both washer nozzles. Top off fluid level if needed after testing.
Reassembly
- Reinstall any engine covers removed during disassembly
- Wipe up any spilled washer fluid from painted surfaces to prevent staining
- Dispose of old washer fluid according to local regulations
Verification
- Start engine and verify washer pump operates quietly without unusual noise
- Test washer spray on windshield from both driver and passenger sides
- Inspect all connections for leaks with engine running and washer activated
- Check fluid level after testing and top off if necessary
- Verify no washer fluid odor inside engine compartment indicating leaks
