When to Inspect the Engine Air
Cleaner/Filter
Inspect or replace the air cleaner/
filter at the scheduled maintenance
intervals. See Maintenance
Schedule on page 11-3. If driving in
dusty/dirty conditions, inspect the
filter at each engine oil change.
How to Inspect the Engine Air
Cleaner/Filter
To inspect the air cleaner/filter,
remove the filter from the vehicle
and lightly shake it to release loose
dust and dirt. If the filter remains
covered with dirt, a new filter is
required. Never use compressed air
to clean the filter.
To inspect or replace the engine air
cleaner/filter:
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. Inspect or replace the engine air
cleaner/filter. Make sure that the
filter fits properly into the
housing.
5. Reinstall the cover and fasten
the retaining clips.
Warning
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. Use caution when
working on the engine and do not
drive with the air cleaner/filter off.
Vehicle Care
Caution
If the air cleaner/filter is off, dirt
can easily get into the engine,
which could damage it. Always
have the air cleaner/filter in place
when you are driving.
