Are you attempting to replace the halogen bulbs, or the entire headlamp assembly?
I have instructions for replacing the bulbs, but unfortunately I do not show replacing the assembly in my database.
Here are the bulb replacement procedures.
HEADLIGHT BULB REMOVAL/INSTALLATION Low-beam
Headlight bulb removal note
It may be necessary to move components to allow access to the replacement of the headlamp bulbs. battery, air cleaner housing, coolant bottle, windshield washer bottle.
I hope this is the information you are looking for
