Fig. Fig. 5: A dirty filter, such as this, should be replaced

The filter should be replaced at least every 30,000 miles (48,309 km) or 24 months.

All vehicles covered in this guide are equipped with a disposable paper cartridge air cleaner element. At every tune-up or sooner, if the car is operated in a dusty area, remove the housing cover and element. Inspect the element and replace if necessary.

  1. On carbureted engines, unscrew the wingnut on top of the air cleaner housing and, if equipped, unsnap the spring clips around the edge of the housing. On fuel injected engines, unsnap the spring clips around the edge of the housing.
  2.  
  3. Lift off the housing cover and remove the air cleaner element.
  4.  
  5. Check the element by holding a drop light or equivalent up to the filter. If light can be seen through the filter, the filter is not clogged. Replace the filter, however, if it is extremely dirty. Loose dust can sometimes be removed by striking the filter against a hard surface several times or by blowing through it with compressed air from the inside out.
  6.  

To install:

Carbureted engines use a round element and fuel injected engines use a panel-type element. The panel (flat, rectangular) elements have the word UP printed on them; be sure the side with UP on it faces upward.

  1. Before installing either the original or a replacement filter, wipe out the inside of the air cleaner housing with a clean rag or paper towel.
  2.  
  3. Install the air cleaner element, then seat the top cover on the bottom housing and secure the cover with the spring clips, if so equipped. On carbureted models, fasten the wingnut.
