When to Inspect

Inspect the air cleaner/filter every 15,000 miles
(25,000 km) and replace every 30,000 miles
(50,000 km). If you are driving in dusty/dirty conditions,
inspect the filter at each engine oil change.

How to Inspect

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

1. Loosen the screw and clamp on the air duct.

2. Lift up on the two clips

located on the top of
the filter assembly
to unlock the side
cover.

3. Disconnect the duct and reposition it while removing

the side cover.

4. Pull out the filter.

5. Inspect or replace the filter if needed.

6. Reinstall the filter.

7. Push down on the two clips located on top of the

filter assembly to lock the side 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 flame if the engine backfires. If it isn’t
there and the engine backfires, you could
be burned. Don’t 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 your engine, which will damage it.
Always have the air cleaner/filter in place when
you’re driving.
