At first, read if your owners manual says something about a special interval (i.e. 30,000 miles or so). If you think its time to change, pull them out, but be careful not to destroy the contacts. There are some stickers under the hood. One of them tell you what spark plugs to use and the gap between the contacts. Use a small special tool for testing the gap and adjusting it. You can buy it in any part store or a gas station for a couple $$. Follow the safety instruction while working on your engine!

The spark plugs are usable goods just like air filter so you have to consider buying new ones since you will have more power and more miles for the same burnt fuel. You know when is the time to change when you lack power and less mpg, engine start after few rotations on battery instead of a fast start and when you remove the spark plugs you notice dirt on the head of the plugs.

SOURCE: 2006 buick lacrosse how to replace headlight low

The bright light fitting is the same as the dim so take it apart fist to see how the cover screws off/on and the light comes out. Both the cover and the bulb are removed by a standard twist to the counterclockwise and replaced by a twist to the clockwise. Now to the dim light. You have to release the entire light assembly before you can remove the screw-on cover to reach the light. On the rear edge of the light unit closest to the engine is a white locking tab. Pull that tab up just to the point where it releases…pull too far and it locks again. Next, locate the other locking bracket which is a metal bracket in the center-rear of the light assembly. This bracket is held down by a screw. Remove the screw with a 10mm wrench. Lift the bracket just like you did the white bracket. You should now be able to pull (or pry) the entire light unit forward a little. Depending on the size of your hands this might be enough. If not, then you need to release the plastic bumper assembly to give you a little more space. This is done by removing two expansion locking pins, one that holds the little plastic strip down between the bright and dim lights and one that is located inside a rubber bumper on the engine side of the light unit. To remove these locking pins, pull or pry up the little tab in the center of the pin just like you were pulling a nail by the head. That should give you a little more space.

One high beam not working 2006 Buick lacrosse


Sampson, sounds like a bunt out bulb, which will need changed.
If you feel comfortable doing it yourself. Basically three screws, and you have to pull one plastic fastener from the fascia (bumper) and pull the bumper back a bit, and pull the assembly out. I believe it is in the manual, not bad to do. I will post a link to tell or show you how to do it. Press the helpful button

Can a shade tree mechanic change spark plugs in a 2006 buick lacrosse 3.8


Of course you can, you may need a few tools such as a spark plug socket with a flex attached and a few extensions 3/8 drive but other then that it would be just like any other car. Take your time doing one at a time and wha-la you are done.
First grab the back of the boot and twist a little left and right to break the natural adhersion between the plug and wire then slide the heat shield back and pull off wire, change plug and reinstall with dilectic grease
