2007 SATURN OUTLOOK engine

Overheated Engine Protection
Operating Mode
This emergency operating mode lets your vehicle
be driven to a safe place in an emergency
situation. If an overheated engine condition exists,
an overheat protection mode which alternates
ring groups of cylinders helps prevent engine
damage. In this mode, there is a signicant loss in
power and engine performance. The temperature
gage indicates an overheat condition exists.
Driving extended distances and/or towing a trailer
in the overheat protection mode should be
avoided.
Notice:After driving in the overheated engine
protection operating mode, to avoid engine
damage, allow the engine to cool before
attempting any repair. The engine oil will be
severely degraded. Repair the cause of coolant
loss, change the oil and reset the oil life
system. SeeEngine Oil on page 387.
Cooling System
When you decide it is safe to lift the hood, here is
what you will see:
A. Engine Coolant Reservoir
B. Radiator Pressure Cap (covered)
C. Engine Cooling Fans

{CAUTION:
An electric engine cooling fan under the
hood can start up even when the engine
is not running and can injure you. Keep
hands, clothing, and tools away from any
underhood electric fan.
If the coolant inside the coolant recovery tank is
boiling, do not do anything else until it cools down.
The vehicle should be parked on a level surface.
When the engine is cold, the coolant level
should be at least up to the FULL COLD mark. If it
is not, you may have a leak at the pressure cap
or in the radiator hoses, heater hoses, radiator,
water pump or somewhere else in the cooling
system.
{CAUTION:
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 re,
and you could be burned. Get any leak
xed 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, both fans
should be running. If they are not, your vehicle
needs service.
Notice:Engine damage from running your
engine without coolant is not covered by your
warranty.
Notice:Using coolant other than DEX-COOL
®
may cause premature engine, heater core, or
radiator corrosion. In addition, the engine
coolant could require changing sooner, at
30,000 miles (50 000 km) or 24 months,
whichever occurs rst. Any repairs would not
be covered by your warranty. Always use
DEX-COOL
®(silicate-free) coolant in your
vehicle.
How to Add Coolant to the Coolant
Recovery Tank
Notice:This vehicle has a specic coolant ll
procedure. Failure to follow this procedure
could cause your engine to overheat and
be severely damaged.If you have not found a problem yet, check to see
if coolant is visible in the coolant recovery tank.
If coolant is visible but the coolant level is not at or
above the FULL COLD mark, add a 50/50 mixture
of clean, drinkable water and DEX-COOL
®
coolant at the coolant recovery tank, but be sure
the cooling system, including the coolant recovery
tank pressure cap, is cool before you do it. See
Engine Coolant on page 396for more information.
{CAUTION:
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 radiator pressure cap — even
a little — they can come out at high
speed. Never turn the cap when the
cooling system, including the radiator
pressure cap, is hot. Wait for the cooling
system and radiator pressure cap to cool
if you ever have to turn the pressure cap.

{CAUTION:
Adding only plain water to your cooling
system can be dangerous. Plain water, or
some other liquid such as alcohol, can
boil before the proper coolant mixture will.
Your vehicle’s coolant warning system is
set for the proper coolant mixture. With
plain water or the wrong mixture, your
engine could get too hot but you would
not get the overheat warning. Your engine
could catch re and you or others could
be burned. Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
®coolant.
Notice:In cold weather, water can freeze and
crack the engine, radiator, heater core and
other parts. Use the recommended coolant and
the proper coolant mixture.
{CAUTION:
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.
When the coolant in the coolant recovery tank is
at the FULL COLD mark, start your vehicle. If
the overheat warning continues, there is one more
thing you can try. You can add the proper
mixture directly to the radiator, but be sure the
cooling system is cool before you do it.

1. To remove the panel that covers the radiator
cap, detach fasteners and lift off panel.
2. Remove the radiator pressure cap when the
cooling system, including the upper radiator
hose, is no longer hot. Turn the pressure cap
slowly counterclockwise about one full turn.
If you hear a hiss, wait for that to stop. A hiss
means there is still some pressure left.3. Keep turning the
pressure cap slowly,
and remove it.
4. Fill the radiator with the proper DEX-COOL®
coolant mixture, up to the base of the ller
neck. SeeEngine Coolant on page 396
for more information about the proper coolant
mixture.

5. Fill the coolant recovery tank to the FULL
COLD mark.
6. Reinstall the cap on the coolant recovery tank,
but leave the radiator pressure cap off.7. Start the engine and let it run until you can
feel the upper radiator hose getting hot.
Watch out for the engine cooling fan.
8. By this time, the coolant level inside the
radiator ller neck may be lower. If the level is
lower, add more of the proper DEX-COOL
®
coolant mixture through the ller neck until the
level reaches the base of the ller neck.
Replace the pressure cap.
At any time during this procedure if coolant begins
to ow out of the ller neck, reinstall the pressure
cap. Be sure to secure it tightly.

Power Steering Fluid
The power steering uid
reservoir is located
toward the front of the
engine compartment
on the passenger’s side
of the vehicle. See
Engine Compartment
Overview on page 386
for reservoir location.
When to Check Power Steering Fluid
It is not necessary to regularly check power
steering uid unless you suspect there is a leak in
the system or you hear an unusual noise. A
uid loss in this system could indicate a problem.
Have the system inspected and repaired.
How to Check Power Steering Fluid
To check the power steering uid, do the following:
1. Turn the key off and let the engine
compartment cool down.
2. Wipe the cap and the top of the reservoir clean.
3. Unscrew the cap and wipe the dipstick with a
clean rag.
4. Replace the cap and completely tighten it.
5. Remove the cap again and look at the
uid level on the dipstick.
The uid level should be somewhere within the
cross-hatched area on the dipstick. If the uid is at
the ADD mark, you should add uid.
What to Use
To determine what kind of uid to use, see
Recommended Fluids and Lubricants on page 497.
Always use the proper uid.
Notice:Use of the incorrect uid may damage
your vehicle and the damages may not be
covered by your warranty. Always use the
correct uid listed in Recommended Fluids and
LubricantsRecommended Fluids and
Lubricants on page 497.

Windshield Washer Fluid
What to Use
When adding windshield washer uid, be sure to
read the manufacturer’s instructions before
use. If operating your vehicle in an area where the
temperature may fall below freezing, use a uid
that has sufficient protection against freezing.
Adding Washer Fluid
When the windshield washer uid reservoir is low,
a WASHER FLUID LOW ADD FLUID message
will be displayed on the Driver Information Center
(DIC). SeeDIC Warnings and Messages on
page 239for more information.
Open the cap with the
washer symbol on it.
Add washer uid
until the tank is full. See
Engine Compartment
Overview on page 386
for reservoir location.Notice:
When using concentrated washer uid,
follow the manufacturer’s instructions
for adding water.
Do not mix water with ready-to-use washer
uid. Water can cause the solution to
freeze and damage your washer uid tank
and other parts of the washer system.
Also, water does not clean as well
as washer uid.
Fill the washer uid tank only
three-quarters full when it is very cold.
This allows for uid expansion if freezing
occurs, which could damage the tank if it is
completely full.
Do not use engine coolant (antifreeze) in
your windshield washer. It can damage
the vehicle’s windshield washer system
and paint.
