The air cleaner assembly also functions as a flame arrester if the engine should backfire. It should be installed at all times when operating the vehicle.

An air cleaner and element is used to keep airborne dirt and dust out of the air flowing through the engine. Proper maintenance is vital, as a clogged element will undesirably enrichen the fuel mixture, restrict air flow and power, and allow excessive contamination of the oil with abrasives.

All models covered in this guide are equipped with a disposable, paper cartridge air cleaner element. The filter should be checked at every tune-up (sooner if the car is operated in a dusty area). Loose dust can sometimes be removed by striking the filter against a hard surface several times or by blowing through it with compressed air. The filter should be replaced every 30,000 miles or every 24 months.

To remove the filter, unscrew the wing nut(s), lift off the housing cover and remove the filter element. There are thumb latches which will also have to be released before removing the housing cover. Before installing the original or the replacement filter, wipe out the inside of the housing with a clean rag or paper towel. Install the paper air cleaner filter, seat the top cover on the bottom housing and tighten the wing nut(s). Clip on the thumb latches if so equipped.
