When to Inspect the Engine Air
Cleaner/Filter
Inspect the air cleaner/filter every 15, 000 miles
(25 000 km) and replace every 30, 000 miles
(50 000 km). If you are driving in dusty/dirty conditions,
inspect the filter at each 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 both wing 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 three tabs located on the rear of the cover.
