Cooling System
The cooling system allows the
engine to maintain the correct
working temperature.
A. Electric Engine Cooling Fan(Out of View)
B. Coolant Surge Tank with Pressure Cap
{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. Notice:
Using coolant other than
DEX‐COOL
®can cause premature
engine, heater core, or radiator
corrosion. In addition, the engine
coolant may require changing
sooner, at the first maintenance
service after each 30,000 miles
(50 000 km) 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.

Notice:If extra inhibitors and/or
additives are used in the vehicle
cooling system, the vehicle
could be damaged. Use only the
proper mixture of the engine
coolant listed in this manual for
the cooling system. See
Recommended Fluids and
Lubricants on page 11‑6 for
more information.
Checking Coolant
The vehicle must be on a level
surface when checking the coolant
level.
Check to see if coolant is visible in
the coolant surge tank. If the coolant
inside the coolant surge tank is
boiling, do not do anything else until
it cools down. If coolant is visible
but the coolant level is not between
the Minimum and Maximum marks,
add a 50/50 mixture of clean,
drinkable water and DEX-COOL
coolant at the coolant surge tank, but be sure the cooling system is
cool before this is done. See
Engine
Coolant on page 10‑18 for more
information.
The engine coolant surge tank is
located in the rear of the engine
compartment on the driver side
of the vehicle. See Engine
Compartment Overview on
page 10‑8 for more information on
location.
{WARNING
Turning the surge tank pressure
cap when the engine and radiator
are hot can allow steam and
scalding liquids to blow out and
burn you badly. Never turn the
surge tank pressure cap —even a
little —when the engine and
radiator are hot.
When the engine is cold, the coolant
level should be between the
Maximum (A) and Minimum (B)
marks on the coolant surge tank.
The level rises at engine operation
temperature and drops again when
the engine cools down.
The coolant should be between the
Maximum (A) and Minimum (B)
marks, when the engine is cold. If it
is not, there could be a leak in the
cooling system.

How to Add Coolant to the
Coolant Surge Tank
{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.
{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 no coolant is visible in the surge
tank, add coolant as follows:
1. Remove the coolant surge tank pressure 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
two or two and one-half turns. If a hiss is heard, wait for
that to stop. This will allow any
pressure still left to be vented
out the discharge hose.
2. Then keep turning the pressure
cap slowly and remove it.

3. Fill the coolant surge tankwith the proper mixture to the
Maximum mark on the coolant
surge tank. Wait about
5 minutes, then check to see if
the level is below the mark. If the
level is below the Maximum
mark, add additional coolant to
bring the level up to the mark.
Repeat this procedure until the
level remains constant at the
Maximum mark for at least
five minutes. 4. With the coolant surge tank
pressure cap off, start the
engine and let it run until the
upper radiator hose can be felt
getting hot. Watch out for the
engine cooling fan.
By this time, the coolant level
inside the coolant surge tank
may be lower. If the level is
lower than the Maximum mark,
add more of the proper mixture
to the coolant surge tank until
the level reaches the mark.
5. Replace the pressure cap. Be sure the pressure cap is
hand-tight and fully seated.
Notice: If the pressure cap is not
tightly installed, coolant loss and
possible engine damage may
occur. Be sure the cap is properly
and tightly secured.
Engine Overheating
The vehicle has an indicator to
warn of the engine overheating.
There is a coolant temperature
gauge on the instrument panel
cluster. See Engine Coolant
Temperature Gauge on page 5‑11.
If the decision is made not to lift the
hood when this warning appears,
get service help right away. See
Roadside Assistance Program on
page 13‑6.
If the decision is made to lift the
hood, make sure the vehicle is
parked on a level surface.
