Steps
Release the bumper cover
Protect painted edges and remove the lower, upper, and fender-corner bumper fasteners. Disconnect fog and side-marker wiring, then lift the cover away with support.
Remove the headlight assembly
Unplug the headlamp connectors and remove the assembly mounting bolts. Guide the lamp out without pulling on the harness or scratching the fender.
Fit the replacement headlight
Remove protective film and transfer bulbs or components if required. Seat the assembly's locating points correctly, install its fasteners evenly, and reconnect each plug.
Reinstall bumper and check beam
Reconnect marker and fog lamps, align the bumper at the fender guides, and reinstall the shields and fasteners. Test all lights and check headlamp aim against a wall on level ground.
Check your vehicle’s repair manual for exact specifications and fit.
