When to Inspect the Engine Air Cleaner/Filter

Inspect the air cleaner/filter at the Maintenance II intervals and replace it at the first oil change after each 50,000 mile (83 000 km) interval. See Scheduled Maintenance for more information. If you are driving in dusty/dirty conditions, inspect the filter at each engine oil change.

How to Inspect the Engine Air Cleaner/Filter

To inspect the air cleaner/filter, remove the filter from the vehicle and lightly shake the filter to release loose dust and dirt. If the filter remains caked with dirt, a new filter is required.

To inspect or replace the air cleaner/filter, do the following:

  1. Remove the two clamps on the duct.

  4. Unlatch the two hooks on top of the engine air cleaner/filter housing.
  5. Inspect or replace the engine air cleaner/filter.
  6. Align the tabs located on the bottom of the panel with the slots at the bottom of the housing.
  7. Latch the hooks to secure the panel in place. If the panel moves easily, check that the tabs are seated correctly in the slots.
  8. Put the duct back on and reinstall the clamps.

Caution: Operating the engine with the air cleaner/filter off can cause you or others to be burned. The air cleaner not only cleans the air; it helps to stop flames if the engine backfires. If it is not there and the engine backfires, you could be burned. Do not drive with it off, and be careful working on the engine with the air cleaner/filter off.

Notice: If the air cleaner/filter is off, a backfire can cause a damaging engine fire. And, dirt can easily get into the engine, which will damage it. Always have the air cleaner/filter in place when you are driving.
