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.
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.
