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 (83 000 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 in the 3.6L V6 or 4.6L V8
engines, do the following:
1. Remove the two screws located on the top of
the cover.
2. Disconnect the coolant recovery hose so that it is
not going across the top of the engine air
cleaner/filter.
3. Loosen the clamp and remove the duct from the
passenger’s side of the engine air cleaner/filter.
4. The two sides of the airbox are hinged at the
bottom. Open the airbox by pushing the top of
the airbox cover toward the engine.
5. Remove the air filter by lifting it straight up through
the opening in the airbox.
6. Inspect or replace the engine air cleaner/filter. See
Normal Maintenance Replacement Parts on
page 6-14 for the correct part number for the filter.
7. Reinstall the cover by reversing Steps 1 through 4.
If your vehicle has the 4.4L V8 STS-V engine, there
is a special procedure for checking and changing the air
cleaner/filter. Because this procedure is difficult, you
should have this done at the dealership service
department. Contact your dealer for additional
information or the procedure can be found in the service
manual. To purchase a service manual, see Service
Publications Ordering Information on page 7-14.
