Engine Air Cleaner/Filter (Gasoline Engines) - GMC Sierra Classic 2007 Owner's Manual

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 476 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 613 for more information. If you are driving
in dusty/dirty conditions, inspect the filter at
each engine oil change.
