Engine Air Cleaner/Filter
See Engine
Compartment Overview
on page 402 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 517 for
more information. If you are driving in dusty/dirty
conditions, inspect the filter at each engine
oil change.
