See Engine Compartment Overview for the location of the engine air cleaner/filter and change indicator (if equipped).

When to Inspect the Engine Air Cleaner/Filter

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 restriction indicator at every oil change and replace the filter when the indicator tells you to. When the change indicator turns black or is in the red/orange change zone, change the filter and reset the indicator. Vehicles without a change indicator, 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 remove and reinstall the filter and reset the indicator (if equipped), do the following:

The engine air cleaner/filter is located near the center of the engine compartment.

  1. Unhook the retainer clips and remove the cover.
  2. Lift the filter out of the engine air cleaner/filter housing. Care should be taken to dislodge as little dirt as possible.
  3. Clean the engine air cleaner/filter housing.
  4. Install the new engine air cleaner/filter into the engine air cleaner/filter housing. Make sure that it fits properly into the housing.
  5. Reinstall the cover and fasten the retaining clips.

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.
