How to Inspect the Engine Air
Cleaner/Filter
Do not start the engine or have the
engine running with the engine air
filter housing open. Before removing
the engine air filter, make sure that
the engine air filter housing and
nearby components are free of dirt
and debris. Remove the engine air
filter. Lightly tap and shake the
engine air filter (away from the
vehicle) to release dust and dirt.
Inspect the engine air filter for
damage, and replace if damaged.
Do not clean the engine air filter or
components with water or
compressed air.
