Warnings

Tools required

Parts

• Windshield washer pump × 1 — Use OEM specification
• Washer pump grommet (if damaged) × 1 — Use OEM specification

Fluids

• Windshield Washer Fluid — 3.5 qt

Preparation

1. Park vehicle on level surface and ensure it is powered off completely
2. Allow vehicle to cool if recently driven
3. Gather all necessary tools and replacement parts
4. Place drain pan beneath front driver side area where washer reservoir is located
5. Have shop towels ready to catch residual fluid

Procedure

1. 1

   Access the washer fluid reservoir
   Open the hood and locate the washer fluid reservoir on the driver side of the engine compartment. Remove the reservoir cap to relieve any pressure and allow easier draining during pump removal.
2. 2

   Remove the front driver side wheelwell liner (partial)
   Turn the front wheels to the right for better access. Remove the plastic push-pin fasteners securing the front portion of the driver side wheelwell liner using the trim panel removal tool. Only the front section needs to be peeled back to access the lower portion of the reservoir. You do not need to remove the entire liner.
3. 3

   Locate and access the washer pump
   From below, through the wheelwell opening, locate the washer pump mounted in the lower portion of the reservoir tank. The pump is a cylindrical component with electrical connector and outlet hose. Position your drain pan directly beneath the pump location.
4. 4

   Disconnect the electrical connector
   Locate the electrical connector on the washer pump. Press the locking tab and carefully pull the connector straight off the pump terminals. Do not pull on the wires themselves. Secure the connector away from the work area to prevent contamination from washer fluid.
5. 5

   Disconnect the washer hose
   Using needle nose pliers if needed, carefully remove the washer hose from the pump outlet. Be prepared for washer fluid to drain from both the hose and reservoir. Have shop towels ready. If the hose is stiff or difficult to remove, gently work it back and forth while pulling.
6. 6

   Remove the washer pump from reservoir
   Grasp the pump body firmly and rotate it counterclockwise approximately 1/4 turn to unlock it from the reservoir mounting bayonet. Pull the pump straight out of the reservoir along with its rubber grommet seal. Remaining washer fluid will drain into your catch pan. Inspect the rubber grommet for cracks or deterioration.
7. 7

   Install the new washer pump
   Install the rubber grommet onto the new washer pump if it is not pre-installed. Ensure the grommet is seated properly in the pump groove. Insert the pump assembly into the reservoir opening, aligning the tabs. Push the pump in fully and rotate clockwise approximately 1/4 turn until it locks into place. Verify the pump is seated securely and the grommet creates a seal.
8. 8

   Reconnect washer hose and electrical connector
   Push the washer hose firmly onto the pump outlet until it is fully seated. The connection should be secure with no gaps. Connect the electrical connector to the pump terminals, ensuring it clicks into place and the locking tab engages fully.
9. 9

   Reinstall wheelwell liner
   Reposition the wheelwell liner to its original location and secure all push-pin fasteners that were removed. Ensure the liner is properly seated and all fasteners are fully engaged.
10. 10

    Refill washer fluid reservoir
    Using the appropriate windshield washer fluid, refill the reservoir to the FULL mark (approximately 3.5 quarts capacity). Do not overfill. Replace the reservoir cap securely.

Reassembly

1. Ensure all electrical connections are secure and properly locked
2. Verify wheelwell liner is properly reinstalled with all fasteners engaged
3. Check that no tools or materials were left in the engine compartment or wheelwell
4. Wipe up any spilled washer fluid from components and surrounding areas

Verification

• Turn the vehicle to accessory mode or start the vehicle
• Activate the windshield washer function and verify fluid sprays properly onto the windshield
• Check for leaks around the pump mounting area, hose connection, and electrical connector
• Verify washer fluid level has not dropped excessively, indicating a leak
• Test both front windshield washer operation (if equipped with rear washer, that system is separate)
• Listen for normal pump operation without unusual noises or grinding
• Inspect the wheelwell area for any fluid drips after testing
