Engine Air Cleaner/Filter

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.
5-20
See Engine Compartment
Overview on page 5-14 for
the location of the engine
air cleaner/filter and the air
filter restriction indicator,
if the vehicle has one.
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 (80 000 km) interval. See Scheduled
Maintenance on page 6-4 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 by following Steps 1
through 6. 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.
