An air cleaner is used to keep air-borne dirt and dust out of the air flowing through the engine. Proper maintenance is vital, as a clogged element will undesirably richen 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 (never more than 70 psi).
REMOVAL & INSTALLATION
See Figures 1 through 5
Unscrew the nut(s) (if so equipped), lift off the housing cover and remove the filter element. Many models may also have three or four 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 lint-free rag or paper towel soaked in kerosene. Install the paper air cleaner filter, seat the top cover on the bottom housing and tighten the nut(s). Clip on the thumb latches if so equipped.
