Chevy Aveo Headlight
Two Top Bolts
One Lower Inner Bolt
This automotive maintenance tutorial was specifically written to assist owners of the revised first generation (2007, 2008, 2009, 2010 & 2011) GM Chevrolet Aveo sedan in changing a burnt out combination low and high beam headlight bulb or the front turn signal light bulb.

Owners of other General Motors vehicles such as the Buick Verano, Regal, LaCrosse, Cascada, Encore, Enclave, Envision, GMC Canyon, Sierra 1500, Terrain, Yukon, Denali, Savana, Spark, Sonic, Cruze, Malibu, Impala, Volt, Camaro, Corvette, SS, Trax, Equinox, Traverse, Tahoe, Suburban, Colorado, Silverado and Express may also find these DIY instructions to be helpful.

The replacement bulb part numbers are as follows: Dual Filament Low & High Beam Headlight Bulb # 9003 and Front Turn Signal Light Bulb 2357A (or PY21W).

To access and replace the bulbs, you'll need a 10mm socket, an extension bar and a 1/4" drive ratcheting wrench.

Loosen Outer Bolt
Loosen 2nd Top Screw
3rd Screw - Inner Corner
The first two steps are to open the hood and then move to the side of the car with the burnt out headlight bulb.

You may be able to reach the low/high beam headlight bulb on the passenger side of the vehicle with out the use of tools, but it is much easier to access the bulbs by just removing the headlight assembly from the front of the car.

The 12V battery blocks access to the bulbs on the driver's side of the car.

The headlight housing is held in place by three bolts.

There are two bolts on the top of the housing and the third is located near the inner corner of the assembly.

Loosen the three bolts by turning them counterclockwise with the 10mm socket and 1/4" drive ratcheting wrench.

You will need an extension bar to reach the third screw which is recessed in between the inner edge of the housing and the front bumper cover.

3 Bolts Removed
Pull Off Headlight Housing
Headlight Assembly Removed
Set the three bolts aside in a safe place.

Gently pull the headlight housing straight off the front of the car.

Back of Headlight
Pull Off Power Plug
Remove Rubber Gasket
Turn over the headlight housing to access the bulb sockets.

Pull the tan plastic electrical connector for the low/high beam headlight bulb straight off the electrical contacts.

Then gently pull the black rubber gasket or dust cover off the back of the headlight housing.

Rubber Dust Cover

Set the black rubber dust cap aside in a safe place.

The old headlight bulb is held in place by two metal arms that act as retaining clips.

Pull Out Old Light Bulb
Gently squeeze together the two metal loops at the end of the retaining arms to release them.

Swing open the two metal retaining arms until they are out of the way.

Pull the old light bulb straight out of the socket.

Osram 9003 Bulb
Empty Bulb Socket
Insert New # 9003 Halogen
Try to avoid touching the glass part of the new halogen bulb with your fingers or anything greasy in the engine bay.

If you do get the new bulb dirty, wipe it clean with a paper towel moistened with rubbing alcohol.

Insert the new # 9003 dual filament combination low & high beam headlight bulb straight in to the housing.

Swing Down Retaining Arms
Squeeze Together Tabs
Retaining Clips Secured
Swing the metal retaining arms down over the new bulb.

Double check that the new headlight bulb is securely installed.


Rubber Dust Cap
Push On Rubber Gasket
Turn Signal Bulb Socket
Push the rubber dust cover back in to place over the base of the new headlight bulb.

Since I was also replacing the turn signal light bulb, I didn't immediately replace the electrical connector for the headlight bulb to give myself more working room.

If you are only replacing the low/high beam bulb, push on the tan plastic power plug to complete the job.

1/4 Turn Counterclockwise
Bulb Socket Removed
Push Down & 1/4 Turn CC
Rotate the front turn signal light bulb socket 1/4 turn counterclockwise before pulling it straight out of the housing.

Push the old bulb down in to the socket and rotate it 1/4 turn counterclockwise before pulling it straight out.

Push On Headlight Housing
Headlight Assembly Replaced
Spin In 10mm Bolts
Slide the headlight assembly back in to place on the front corner of the car.

Spin in the three 10mm bolts a few turns by hand to prevent them from becoming cross threaded.

Replace 2nd 10mm Bolt
3rd Bolt - Inner Edge

Tighten the three bolts by turning them clockwise with the 10mm socket and 1/4" drive ratcheting wrench.
Tighten 2nd Bolt

Test New Headlight Bulb
Try to avoid over tightening the three bolts to prevent from cracking the plastic mounting tabs.

Test the new light bulbs by turning on the headlights, activating the hazard signals and flashing the high beams.
