When to Inspect

If your vehicle is equipped with a filter change indicator it will let you know when the filter needs to be replaced. Inspect the air cleaner/filter every 15,000 miles (25 000 km) and replace the filter if necessary. Vehicles without a change indicator inspect the air cleaner/filter every 15,000 miles (25 000 km) and replace the filter every 30,000 miles (50 000 km). If you are driving in dusty/dirty conditions, inspect the filter or change indicator at each engine oil change.

How to Inspect

Locate the filter change indicator. When the change indicator turns black, or is in the red/orange "change" zone, replace the filter and reset the indicator. 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 filter and reset the indicator (if equipped), do the following:

  1. Remove the screws on the engine cleaner/filter and lift off the cover.
  2. Remove the air cleaner/filter from the housing. Care should be taken to dislodge as little dirt as possible.
  3. Install the new engine air cleaner/filter.
  4. Reinstall the cover and tighten the screws.

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.
