Parts

  • Washer fluid reservoir × 1 — Use OEM specification
  • Washer pump grommet × 1 — Use OEM specification

Fluids

  • Windshield Washer Fluid — 3.5 qt

Preparation

  1. Park vehicle on level surface and engage parking brake
  2. Allow engine to cool if recently driven
  3. Place drain pan or bucket beneath left front of vehicle
  4. Gather all necessary tools and new parts

Procedure

  1. 1
    Access the washer reservoir
    Open 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.
  2. 2
    Disconnect the washer pump electrical connector
    Locate 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.
  3. 3
    Disconnect the washer hose
    Locate 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.
  4. 4
    Remove the reservoir mounting bolts
    Locate 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 spec
    Module Mounting Bolts8 Nm (6 lb-ft)
  5. 5
    Remove the reservoir assembly
    Carefully 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.
  6. 6
    Transfer 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.
  7. 7
    Install pump into new reservoir
    Insert 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.
  8. 8
    Install the new reservoir
    Position 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 spec
    Module Mounting Bolts8 Nm (6 lb-ft)
  9. 9
    Reconnect washer hose and electrical connector
    Push 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.
  10. 10
    Fill and test the system
    Fill 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

  1. Reinstall any engine covers removed during disassembly
  2. Wipe up any spilled washer fluid from painted surfaces to prevent staining
  3. 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
