Engine Air Cleaner/Filter
See Engine Compartment
Overview on page 5-12
for the location of the
engine air cleaner/filter.
When to Inspect
Inspect the air cleaner/filter at the Maintenance II
intervals and replace at the first oil change after
50,000 miles (83 000 km). 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
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 screws on the engine air cleaner/filter
and lift off the cover.
2. Remove the air cleaner/filter from the housing. Care
should be taken to dislodge as little dirt as possible.
3. Inspect or replace the engine air cleaner/filter.
4. Reinstall the cover and tighten the screws.
{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 flame 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.
