Warnings

Tools required

Parts

• Fog light assembly × 1 — Use OEM specification or aftermarket equivalent
• Push pin retainers (if damaged) × 2 — Ford W710766-S900

Preparation

1. Park vehicle on level surface and set parking brake
2. Turn off ignition and all lights, allow fog lights to cool if recently used
3. Turn front wheels fully to the side opposite of the fog light being serviced for easier access

Procedure

1. 1

   Access the fog light area
   From underneath the front bumper, locate the fog light assembly. You may need to access from the wheel well or underneath depending on which provides better access. If accessing from wheel well, partially remove the front portion of the inner fender liner by removing 2-3 push pin retainers to gain clearance.
2. 2

   Disconnect electrical connector
   Locate the electrical connector on the back of the fog light assembly. Press the release tab on the connector and pull straight back to disconnect. Do not pull on the wiring harness itself.
3. 3

   Remove fog light mounting fasteners
   Remove the two 10mm mounting bolts securing the fog light assembly to the bumper bracket. Support the fog light assembly with one hand while removing the second bolt to prevent it from falling.

4. 4

   Remove fog light assembly
   Carefully pull the fog light assembly forward and out of the bumper opening. Note the orientation and positioning of any alignment tabs or brackets for reinstallation.
5. 5

   Install new fog light assembly
   Position the new fog light assembly into the bumper opening, ensuring any alignment tabs engage properly with the bumper bracket. The assembly should sit flush with the bumper surface.
6. 6

   Install mounting bolts
   Thread in both 10mm mounting bolts by hand first to ensure proper thread engagement. Tighten the mounting bolts to 42.0 Nm (31 lb-ft) in a cross pattern to ensure even seating of the assembly.

7. 7

   Reconnect electrical connector
   Push the electrical connector onto the back of the fog light assembly until you hear or feel a positive click indicating the locking tab has engaged. Gently tug on the connector to verify it is secure.
8. 8

   Reinstall fender liner
   If the inner fender liner was partially removed, reinstall it by pushing the push pin retainers back into their mounting holes until fully seated. Replace any damaged retainers with new ones.

Reassembly

1. Ensure all push pin retainers are fully seated and the fender liner is secure
2. Verify the fog light assembly sits flush with the bumper and is not loose or misaligned

Verification

• Turn the ignition to the ON position and activate the fog lights using the headlight switch
• Visually confirm both fog lights illuminate properly if both were serviced
• Walk around the vehicle and verify the new fog light assembly is aligned properly with the bumper and opposite side fog light
• Check for any warning lights on the instrument cluster related to exterior lighting
