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 (83 000 km) interval. See Scheduled
Maintenance on page 6-4 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.
To inspect or replace the engine air cleaner/filter, do the
following:
1. Remove the two screws located on the sides of
the cover.
2. Lift the cover off.
3. Inspect or replace the engine air cleaner/filter.
See Normal Maintenance Replacement Parts
on page 6-15 for the correct part number for
the filter.
4. Reinstall the cover by reversing Steps 1 and 2.
{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.
