When to Inspect the Engine Air Cleaner/Filter

Inspect the air cleaner/filter at each oil change and replace it at the first oil change after 25,000 miles (41 500 km). See Scheduled Maintenance for more information.

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 filter, do the following:

  1. Remove the two bolts on the engine air cleaner/filter and lift off the cover.
  2. Twist out the old engine air cleaner/filter and replace it, if necessary.
  3. Reinstall the cover.

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.
