{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.
If the coolant inside the coolant
recovery bottle is boiling, do not do
anything else until it cools down.
The vehicle should be parked on a
level surface.

9-18 Vehicle Care
The coolant level should be
between the MIN and MAX lines.
If it is not, you may have a leak at
the radiator hoses, heater hoses,
radiator, water pump, or somewhere
else in the cooling system.
{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 there seems to be no leak,
with the engine on, check to see
if the electric engine cooling fans
are running. If the engine is
overheating, the fans should be
running. If it is not, your vehicle
needs service. Turn off the engine. Notice:
Using coolant other
than DEX-COOL
®can cause
premature engine, heater core,
or radiator corrosion. In addition,
the engine coolant could require
changing sooner, at 50 000 km
(30,000 miles) or 24 months,
whichever occurs first. Any
repairs would not be covered
by the vehicle warranty. Always
use DEX-COOL
®(silicate-free)
coolant in the vehicle.
Engine Coolant
The cooling system in the vehicle
is filled with DEX-COOL®engine
coolant. This coolant is designed to
remain in the vehicle for five years
or 240 000 km (150,000 miles),
whichever occurs first.
The following explains the cooling
system and how to check and add
coolant when it is low. If there is a
problem with engine overheating,
see Engine Overheating
on
page 9‑23.
What to Use
{WARNING
Adding only plain water to
the cooling system can be
dangerous. Plain water, or some
other liquid such as alcohol, can
boil before the proper coolant
mixture will. The vehicle's coolant
warning system is set for the
proper coolant mixture. With plain
water or the wrong mixture, the
engine could get too hot but you
would not get the overheat
warning. The engine could catch
fire and you or others could be
burned. Use a 50/50 mixture of
clean, drinkable water and
DEX-COOL
®coolant.

Vehicle Care 9-19
Use a 50/50 mixture of clean,
drinkable water and DEX-COOL®
coolant. If using this mixture,
nothing else needs to be added.
This mixture:
.Gives freezing protection down
to−37°C (−34°F), outside
temperature.
.Gives boiling protection up
to 129°C (265°F), engine
temperature.
.Protects against rust and
corrosion.
.Will not damage aluminum parts.
.Helps keep the proper engine
temperature.
Notice: If an improper coolant
mixture is used, the engine could
overheat and be badly damaged.
The repair cost would not be
covered by the vehicle warranty.
Too much water in the mixture
can freeze and crack the engine,
radiator, heater core, and other
parts.
Checking Coolant
The vehicle must be on a level
surface when checking the coolant
level.
Check coolant as follows:
1. Turn the ignition OFF.
2. Locate the coolant recovery bottle. See Engine Compartment
Overview on page 9‑6.
3. Turn the coolant dipstick cap counterclockwise and slowly pull
out the dipstick.
4. There are maximum andminimum markings on the
dipstick. When the engine is
cold, the coolant level should be
at or above the MIN mark on the
dipstick. After the vehicle has
been driven and the engine is at
normal operating temperature,
the level should be somewhere
between half full and the
maximum mark.
5. If the coolant level is correct, replace the dipstick and turn the
cap clockwise to secure.

How to Add Coolant to the
Coolant Recovery Bottle
{WARNING
You can be burned if you spill
coolant on hot engine parts.
Coolant contains ethylene glycol
and it will burn if the engine parts
are hot enough. Do not spill
coolant on a hot engine.
Notice: This vehicle has a
specific coolant fill procedure.
Failure to follow this procedure
could cause the engine to
overheat and be severely
damaged. Notice:
If an improper coolant
mixture is used, the engine could
overheat and be badly damaged.
The repair cost would not be
covered by the vehicle warranty.
Too much water in the mixture
can freeze and crack the engine,
radiator, heater core, and other
parts.
Add coolant as follows:
1. Turn the coolant overflow bottle
dipstick cap counterclockwise
and slowly pull out the dipstick.
2. Pour the coolant into the coolant recovery bottle.
3. When the level is correct, replace the dipstick and turn
the cap clockwise to secure.

{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
Steam and scalding liquids from a
hot cooling system can blow out
and burn you badly. They are
under pressure, and if you turn
the surge tank pressure
cap—even a little —they can
come out at high speed. Never
turn the cap when the cooling
system, including the surge tank
pressure cap, is hot. Wait for the
cooling system and surge tank
pressure cap to cool if you ever
have to turn the pressure cap. If coolant is needed, add the proper
mixture directly to the radiator, but
be sure the cooling system is cool
before this is done.
If no coolant is visible in the coolant
overflow bottle, add coolant as
follows:
3.6 L V6 Engine Fill Procedure
1. Locate the radiator cap. See

and tightly secured.
Engine Overheating
The vehicle has an indicator to warn
of engine overheating.
There is an engine coolant
temperature warning light on
your vehicle's instrument panel.
See Engine Coolant Temperature
Gauge on page 4‑15.
You may decide not to lift the hood
when this warning appears, but
instead get service help right away.
See Roadside Assistance Program
on page 12‑6.
If you do decide to lift the hood,
make sure the vehicle is parked on
a level surface.

Then check to see if the engine
cooling fans are running. If the
engine is overheating, both fans
should be running. If they are not,
do not continue to run the engine
and have the vehicle serviced.
Notice:Engine damage from
running the engine without
coolant is not covered by the
warranty.
Notice: If the engine catches
fire because of being driven
with no coolant, your vehicle can
be badly damaged. The costly
repairs would not be covered by
the vehicle warranty.If Steam Is Coming From The
Engine Compartment
{WARNING
Steam from an overheated engine
can burn you badly, even if you
just open the hood. Stay away
from the engine if you see or hear
steam coming from it. Just turn it
off and get everyone away from
the vehicle until it cools down.
Wait until there is no sign of
steam or coolant before you
open the hood.
If you keep driving when your
engine is overheated, the liquids
in it can catch fire. You or others
could be badly burned. Stop your
engine if it overheats, and get out
of the vehicle until the engine
is cool.
If No Steam Is Coming From
The Engine Compartment
If an engine overheat warning is
displayed but no steam can be seen
or heard, the problem may not be
too serious. Sometimes the engine
can get a little too hot when the
vehicle:
.Climbs a long hill on a hot day.
.Stops after high-speed driving.
.Idles for long periods in traffic.
.Tows a trailer.
If the overheat warning is displayed
with no sign of steam:
1. Turn the air off.
2. Turn the heater on to the highest temperature and to the highest
fan speed. Open the windows as
necessary.
3. In heavy traffic, let the engine idle in N (Neutral) while stopped.
If it is safe to do so, pull off
the road, shift to P (Park) or
N (Neutral) and let the
engine idle.
