REMOVAL & INSTALLATION



See Figures 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10

All of the dust present in the air is kept out of the engine by means of the air cleaner filter element. Proper maintenance is vital, as a clogged element not only restricts the air flow and thus the power, but can also cause premature engine wear.

The filter element should be cleaned every 7,500 miles (12,000 km), or more often if the car is driven under dry, dusty conditions. Remove the filter element and using low pressure compressed air, blow the dirt out.

The filter element used on Toyota vehicles is of the dry, disposable type. It should never be washed, soaked or oiled.

The filter element should be replaced every 18,000 miles (28,960) on the 1971-72; every 24,000 miles (38,616 km) on the 1973-74; every 25,000 miles (40,225 km) on the 1975-77; and every 30,000 miles (48,270 km) on the 1978-85 models; or more often under dry, dusty conditions. Be sure to use the correct one; all Toyota elements are of the same type but they come in a variety of sizes.

  1. Unfasten the wingnut(s) and clips (if so equipped) on top of the air cleaner housing and lift off the top.
  2.  
  3. Lift out the air filter element and clean it with compressed air or replace it.
  4.  
  5. Clean out the filter case with a rag.
  6.  

To install:
  1. Insert the old (cleaned) or new air filter element into the filter housing.
  2.  
  3. Place the air cleaner lid into position and secure with the clips and/or wingnut(s).
