Engine Air Cleaner/Filter

(Gasoline Engines)

If your vehicle has a diesel engine, see "Pickup
Models" under "Engine Air Cleaner/Filter" in
®
the DURAMAX Diesel Supplement for the correct
inspection and replacement procedures.
See Engine
Compartment Overview
on page 480 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 (Gasoline Engine) on
page 617 for more information. If you are driving
in dusty/dirty conditions, inspect the filter at
each engine oil change.
