Pontiac 2008 G6 - Manual (Page 289)

To replace one of these bulbs:
1. Remove the two screws that secure the headlamp
assembly.
2. Loosen the front fascia by removing the plastic
push pins along the top of the tie bar by prying
under the fasteners with a tool.
3. Pull back the front fascia then pull the headlamp
assembly forward, out of the vehicle. You need to
pry the headlamp assembly away from the
fender. This frees the ball stud from its retainer in
the fender bracket.
You might want someone to assist you with the
removal of the headlamp assembly to avoid possible
damage to the vehicle.
4. Remove the bulb access cover by turning it
counterclockwise.
5. Turn the bulb socket counterclockwise and pull out
the bulb assembly.
6. Disconnect the bulb socket from the wiring harness
for headlamps.
For the front turn signal/parking or sidemarker
bulbs, unclip the bulb from the socket.
7. Install a new bulb.
8. Reverse Steps 1 through 4 to reinstall the bulb
assembly and headlamp assembly.
