How to Inspect the Engine Air
Cleaner/Filter
To inspect the air cleaner/filter,
remove the filter from the vehicle
and lightly shake the filter 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, do the following:
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.
