Engine Air Cleaner/Filter
See Engine
Compartment Overview
on page 334
for the
location of the engine air
cleaner/filter and the
air filter restriction
indicator, if the vehicle
has one.
When to Inspect the Engine
Air Cleaner/Filter
If your vehicle has an air filter restriction indicator,
it lets you know when the engine air cleaner/filter
needs to be replaced. On vehicles with a restriction
indicator, you should inspect the air filter
restriction indicator at every oil change and
replace the engine air cleaner/filter when the
indicator tells you to.
On vehicles without an air filter restriction indicator,
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 449 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
Vehicles With an Air Filter Restriction
Indicator
Locate the air filter restriction indicator on the
engine air cleaner/filter cover. When the indicator
turns black or is in the red/orange “change” zone,
replace the filter and reset the indicator. See the
steps following to replace the engine air cleaner/
filter and to reset the air filter restriction indicator.
Vehicles Without an Air Filter Restriction
Indicator
To inspect the air cleaner/filter, remove the engine
air cleaner/filter from the vehicle using the steps
following. When you have the engine air cleaner/
filter removed, lightly shake it to release loose dust
and dirt. If the engine air cleaner/filter remains
caked with dirt, a new filter is required.
