Warning
If part replacement is necessary, the part
must be replaced with one of the same
part number or with an equivalent part.
Use of a replacement part without the
same fit, form, and function may result
in personal injury or damage to the
vehicle.
5. Inspect or replace the engine air
cleaner/filter.
6. Lower the cover, slide it into the
assembly, then secure with the screws.
7. If equipped, reset the engine air filter life
system after replacing the engine air
filter. See Engine Air Filter Life System.
See Maintenance Schedule 0 315 for
replacement intervals.
Warning
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.
Caution
If the air cleaner/filter is off, dirt can
easily get into the engine, which could
damage it. Always have the air
cleaner/filter in place when driving.

Cooling System

The cooling system allows the engine to
maintain the correct working temperature.
