The Chevy air cleaner is a vital component for the efficient running of your vehicle. It filters out any dirt and grime out of the air before it passes into the engine, this in turn allows the engine to operate at peak performance and fuel efficiency.
The 2002 Chevy Cavalier 02 sensor can be found attached to the air cleaner housing. The O2 sensor will be on the back side of the air cleaner housing.
Take the air cleaner off and you will see the carburetor bolted to the top center of the engine. That is what the air cleaner set's on. The top of the carb.
