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 every oil change
and replace at the first oil change after
25,000 miles (40 000 km).
How to Inspect
To inspect the air cleaner/filter, remove the filter from
the vehicle and lightly shake filter to release loose dust
and dirt. If the filter remains caked with dirt, a new
filter is required.
To inspect or replace the filter, do the following:
1. Remove the screws on the engine 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. Install the new 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.
