Steps
Remove the front bumper cover
Release the upper shield clips, wheel well fasteners, and lower splash shield retainers. Free the bumper edges from their side clips and lift the cover away with help, disconnecting any attached lamps if needed.
Remove the headlight assembly
Remove the upper and lower headlight mounting bolts, pull the lamp forward, and unplug its wiring connectors. Support the assembly while disconnecting it to prevent damage to the harness or lens.
Install and align the replacement lamp
Reconnect the harnesses and position the replacement headlight in its mounts. Start the fasteners by hand, align the lamp evenly with the fender and hood, then tighten the bolts to the vehicle specification.
Reinstall the bumper and aim the lights
Align the bumper cover with its side clips and reinstall the lower screws, splash shield retainers, and upper pins. Test all lighting functions and adjust beam aim using the manufacturer's procedure on level ground before night driving.
Check your vehicle’s repair manual for exact specifications and fit.
