Owners of other related GM vehicles such as the Buick Regal, Buick LaCrosse, Saab 9-5, 9-3, Opel Insignia, Saturn Aura, Cadillac BLS, Fiat Croma, Opel Vectra, Signum and Pontiac G6 may also find these DIY instructions to be helpful.

Replacement headlight bulbs for the 08-12 Malibu include the following with their part numbers: Low Beam # H11, High Beam H9, Front Turn Signal 4157NA, and Front Side Marker 168.

The tools needed to complete this procedure include a 7mm socket, a 10 mm socket, a ratcheting wrench, a flat head screwdriver and a pair of needle nose pliers.

Nine of the bolts are the exactly the same but there are two 10mm bolts with larger heads on either side of the hood latch mechanism near the front of the vehicle.

Carefully lift off the radiator cover and set it aside in a safe place.

Some people may choose to remove the wheel entirely for easier access to the wheel well liner.

If you plan on replacing both headlight bulbs at the same time, it may be easier to just remove both front wheels and secure the vehicle with two jack stands.

Move to the front of the vehicle and lay down beneath the front bumper. Locate the black 7mm screws along the black plastic underbody cover and remove them with a socket or wrench.

There is also 1 black plastic rivet that needs to be removed per side of the underbody cover.

If you are only replacing bulbs in one headlight assembly, you'll only need to remove 4-6 7mm screws and 1 pop rivet.

Be sure to keep all of the bolts, screws and rivets organized for easy re-assembly later.

The closest 10mm bolt needs to be removed entirely. The 2nd inner bolt only needs to be loosened a bit.

If the side of the bumper doesn't pull away with moderate force, you may need to loosen the inner 10mm bolt a few more turns. Try to avoid removing it entirely, since it may be difficult to re-insert.

There is one black bolt on the side of the vehicle, one black bolt at the front of the headlight, and two silver bolts that hold a black plastic bracket in place just above the headlight lens.

Pull off the black plastic bracket above the headlight.

Now the headlight assembly can finally be pulled away from the front of the vehicle.

Turn the headlight assembly upside down and gently rest it on the bumper. To help avoid scratching the plastic headlight lens or the painted surfaces of the vehicle, place a rag in between the headlight and the bumper.

Grasp the base of the bulb with your thumb and forefinger. Rotate the base 1/4 turn counter clockwise to unlock it from the assembly. Pull the bulb straight out of the headlight housing.

Insert a new H9 high beam bulb straight into the headlight housing and rotate the base 1/4 turn clockwise to secure it in place.

Rotate the base of the bulb 1/4 turn counter clockwise before pulling it straight out of the headlight housing.

Rotate the side marker light socket 1/4 turn counter clockwise and pull it straight out of the headlight.

Pull the side marker bulb straight out of the socket and push in a new # 168 bulb.

If you would like to have brighter side marker lights, install some compatible replacement 168 LED bulbs.

Insert the bulb and socket back into the headlight and rotate it 1/4 turn clockwise to secure it in place.

Gently pull the wire loom away from the rear of the headlight to make some slack. Then rotate the turn signal bulb's socket 1/4 turn counter clockwise and pull it straight out of the headlight.

Push in a new # 4157NA (or 5702NAK) amber colored light bulb straight into the socket.

Insert the turn signal socket back into the headlight and rotate it 1/4 turn clockwise to secure it in place.

It would be a good idea to test the new light bulb(s) now before re-assembling the bumper.

Turn the headlight back over and line up the plastic spikes on the rear with the holes in the car's metal body work.

Insert the black 10mm bolt on the side of the headlight and tighten it with the socket and ratcheting wrench.

Re-attach the black plastic bracket in place over the top edge of the headlight. Insert and tighten the two silver 10mm bolts.

Lower the top part of the bumper over the black plastic bracket until the bumper is flush with the quarter panel.

Pull aside the wheel well liner and insert the 10mm bolt back into the closest hole. Tighten the closest 10mm bolt and also the other one located a few inches forward of the wheel well.

Replace the 9 standard 10mm bolts, the 2 large head 10mm bolts (front center near hood latch), and the 4 black pop rivets (front edge).

Be sure to record the bulb change in your vehicle's service records.
