Inspect the air cleaner/filter at the Maintenance
II
intervals and replace it at the first oil change after
each 50,000 mile (85 000 km) interval. See
Scheduled Maintenance on page 393 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. Never use
compressed air to clean the filter.
Because this operation can be a little difficult, you
may choose to have this done at the dealership
service department.
To inspect or replace the filter, do the following:
1. Disconnect the MAF sensor, PCV hose,
and both ducts.
2. Pull the entire system from the top of the
engine.
3. Flip the system over and place it on a soft,
non-abrasive surface.
4. Remove the screws that hod the housing and
cover together and lift off the housing.
5. Inspect or replace the engine air cleaner/filter.
6. Reverse the steps to reinstall the system.
Be sure to reinstall the housing tightly.
