DIY, change the air filter on your Buick Century. This replacement is similar for many other front-wheel-drive cars made by GM. The step by step tutorial we show you below is similar on Buick Century V6 models, produced between the years 1997 and 2005.
On this car, the air filter is located in an air box, on the right corner of the engine bay, behind the headlight (as you can see below).
You can remove and replace this filter using a flat blade screwdriver. In the beginning, you will have to loosen up the two clamps shown in the picture below, that hold the air intake hose. Use a screwdriver on them and then you can pull the hose off the engine, by hand.
After you do that, you will have access to the air box that contains the filter. You can open it by pulling up the two metal clips shown in the image below, that hold the lid of the air box. So, in this way you will have access to the air filter, that can now be replaced very easily. Reinstalling is also simple. After you insert the new air filter into the air box and secure it with the clips, you have to reinstall the intake hose and secure it with the clamps. Just make sure you do it correctly and that all the gaskets are sealing and the airflow to the engine is strong.
Why is necessary to replace the air filter? You may wanna consider changing the air filter because a good airflow into the engine is a requisite for its proper operation. Your car’s engine needs a lot of air to run properly and that air must be clean. When air is pumped into the engine efficiently, your car performs better and gets better fuel mileage.
