4. Install the air cleaner housingcover screws.
5. Install the hose to the air cleaner housing mounting arm. The hose
must be routed correctly.
6. Install the air cleaner outlet duct to the air cleaner housing.
7. Tighten the air cleaner outlet duct screw clamp.
8. Attach the electrical connector to the air box.
9. Reinstall the side cover.
{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. Notice:
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 you are driving.
Cooling System
The cooling system allows the
engine to maintain the correct
working temperature.

{WARNING
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.
{WARNING
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.

If coolant is needed, add the proper
DEX-COOL coolant mixture at the
coolant surge tank.
If no coolant is visible in the surge
tank, add coolant as follows:
1. Remove the coolant surge tankpressure cap when the cooling
system, including the coolant
surge tank pressure cap and
upper radiator hose, is no longer
hot. Turn the pressure cap
slowly counterclockwise about
one-quarter turn and then stop.
If you hear a hiss, wait for that to
stop. A hiss means there is still
some pressure left.
2. Keep turning the pressure capslowly and remove it.
3. Fill the coolant surge tank withthe proper mixture, to slightly
above the FROID/FULL COLD
line on the side of the coolant
surge tank.
4. With the coolant surge tank pressure cap off, start the
engine and let it run until you
can feel the upper radiator hose
getting hot. The upper radiator
hose is the top hose coming out
of the radiator, on the passenger
side of the vehicle. Watch out for
the engine cooling fans.
By this time, the coolant level
inside the coolant surge tank
may be lower. If the level is
lower, add more of the proper
mixture to the coolant surge tank
until the level reaches the
FROID/FULL COLD line on the
side of the coolant surge tank.
5. Replace the pressure cap. Be sure the pressure cap is
hand-tight and fully seated.
