When to Inspect the Engine
Air Cleaner/Filter
Inspect the air cleaner/filter at the Maintenance II
intervals and replace it at the first oil change after
each 50,000 mile (80 000 km) interval. See Scheduled
Maintenance on page 6-4 for more information.
If you are 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 the 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, do the following:
1. Loosen and remove the two screws on the top of
the engine air cleaner/filter cover.
2. Lift up the outboard side of the cover at an angle
while pulling toward you. This is necessary due
to the two hinges located on the inboard side
of the cover.
3. Remove the engine air cleaner/filter element and
any loose debris that may be found in the air
cleaner base.
4. Inspect or replace the air filter element.
