When to Inspect the Engine Air Cleaner/Filter

Inspect the air cleaner/filter at every oil change and replace at the first oil change after 25,000 miles (40 000 km).

How to Inspect the Engine Air Cleaner/Filter

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

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


    Object Number: 1250488  Size: B3
  1. Remove the screws that hold the cover on.
  2. Lift off the cover.
  3. Check or replace the engine air cleaner/filter.
  4. Put the cover back on tightly.

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.
