Tools/Supplies Needed:
-10mm socket
-3/8" drive ratchet
-3" extension
Procedure:
First is opening the hood to gain access to the rear of the headlights.
Just to give you a view behind those headlights, there is a done cap that needs to be removed to gain access to the bulb inside.
There will be plastic tabs around the perimeter of the domed cap, grab onto these and twist counterclockwise, then remove.
It was hard for me to get a camera in here without my hand being in the way. As you can see there is the bulb and wire connector.
You can unclip the connector first or after one the bulb is out, whatever is easier for you. For me, I pulled out the tang on the electrical connector and then pushed it off the light.
I then rotated the bulb counterclockwise, and pull out the bulb from the assembly.
I’m replacing the factory bulbs with LEDs to improve the extremely dim light output. Here is a comparison between the bulbs, here you can see the three tabs around the perimeter, two are the same size while one is larger.
The new bulb is then inserted into the light, I’m using LEDs so it’s a little harder to match the reference position of the bulb alignment tabs. You’ll feel it lock into place, push it in, then rotate clockwise until it stops.
After that is plugging in the electrical connector.
Finally is installing the protective cap. Rotate until you can feel those alignment tabs lock into place, then rotate clockwise until it stops.
Moving onto the passenger side requires an extra step. The coolant reservoir tank will need to be removed.
Using a 3/8 drive ratchet with a 3 inch extension and a 10 mm socket, remove the three bolts on the coolant reservoir.
Once those bolts have been removed, then you can push the reservoir back towards the windshield, do not disconnect the lines.
Again the same process as the driver side, remove the domed, cover by rotating counterclockwise. Then to access the bulb, again unclipped the connector and rotate the bulb counterclockwise then pull it straight out.
Finally install the new bulb replacement, then plug in the electrical connector. If you are using an LED bulb, you will need to Work by field in finding out if those alignment tabs are properly in place. Always give the bulb a pull back to make sure it is locked in place.
Then fasten down the coolant reservoir. Install those 3 10mm bolts and tighten. Do not over-tighten as this is only plastic.
After that is testing, the headlights to ensure they are working correctly and you are officially done.
