When to Inspect the Engine Air
Cleaner/Filter
Inspect the air cleaner/filter at the Maintenance II
intervals and replace it at the first oil change after
each 50,000 mile (85 000 km) interval. See
Scheduled Maintenance on page 375 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
To inspect the air cleaner/filter remove the filter
from the vehicle and lightly shake the filter to
release loose dust and dirt. If the filter remains
caked with dirt, a new filter is required. Never
use compressed air to clean the filter.
To inspect or replace the filter, remove the screws
that hold the cover on and lift off the cover.
Be sure to reinstall the cover tightly.
CAUTION:
{
Operating the engine with the air cleaner/
filter off can cause you or others to be
burned. The air cleaner not only cleans the
air; it helps to stop flames if the engine
backfires. If it is not there and the engine
backfires, you could be burned. Do not
drive with it off, and be careful working on
the engine with the air cleaner/filter off.
Notice: If the air cleaner/filter is off, a backfire
can cause a damaging engine fire. And, dirt
can easily get into your engine, which will
damage it. Always have the air cleaner/filter
in place when you are driving.
