3. Inspect or replace the engine air
cleaner/filter.
4. Align the filter correctly.

over the filter and secure with
the screws.
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. Use caution
when working on the engine
and do not drive with the air
cleaner/filter off.
The cooling system allows the
engine to maintain the correct
working temperature.
A. Engine Cooling Fan

B. Engine Coolant Surge Tank and
Pressure Cap
An electric engine cooling fan
under the hood can start up even
when the engine is not running
and can cause injury. Keep
hands, clothing, and tools away
from any underhood electric fan.
Heater and radiator hoses, and
other engine parts, can be very
hot. Do not touch them. If you do,
you can be burned.
Do not run the engine if there is
a leak. If you run the engine, it
could lose all coolant. That could
cause an engine fire, and you
could be burned. Get any leak
fixed before you drive the vehicle.
