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:
1. 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 and any loose
debris that may be found in the air cleaner base.
4. Inspect or replace the air filter element.
To reinstall the cover:
1. Align the two hinges located on the inboard side of
the cover.
2. Push the cover slightly down and towards the
engine to engage the tabs in the hinges and
align the two screws.
3. Tighten the two screws on the top of the engine air
cleaner/filter cover.
