2007 SATURN VUE coolant level

Engine Coolant Temperature Gage
This gage displays the
temperature of the
vehicle’s engine.
If the indicator needle moves into the shaded
area, the engine is too hot. The engine coolant
temperature warning light will also come on when
the engine has overheated. SeeEngine Coolant
Temperature Warning Light on page 173for more
information.
If you have been operating your vehicle under
normal driving conditions, and the engine coolant
temperature warning light comes on, you should
pull off the road, stop your vehicle and turn off the
engine as soon as possible.
Low Coolant Warning Light
This light comes on
briey when you turn
your ignition on.
If this light comes on and stays on, the coolant level
in your vehicle is low. If the light is on along with
an overheat warning, you may have a serious
overheating problem. SeeEngine Coolant
Temperature Gage on page 174.
Notice:Driving with the low coolant warning
light on could cause your vehicle to overheat.
See “Engine Overheating” underEngine
Coolant on page 331. Your vehicle could be
damaged and the damages might not be
covered by your warranty.
SeeEngine Coolant on page 331for information
on what to do. Your vehicle should be serviced as
soon as possible.

Checking Coolant
The surge tank is located on the driver’s
side of the engine compartment. SeeEngine
Compartment Overview on page 314for more
information on location.
{CAUTION:
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.
The vehicle must be on a level surface. When
your engine is cold, the coolant level should
be at the COLD FILL line. When your engine is
warm, the level should be at the COLD FILL line or
a little higher.

{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 surge tank is
boiling, do not do anything else until it cools down.
The vehicle should be parked on a level surface.
The coolant level should be at the COLD FILL line.
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.
{CAUTION:
Heater and radiator hoses, and other
engine parts, can be very hot. Do not
touch them. If you do, you can be burned.
CAUTION: (Continued)
CAUTION: (Continued)
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 fan
is running. If the engine is overheating, the
fan should be running. If it is not, your vehicle
needs service. Turn off the engine.
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
Surge 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 surge tank. If coolant
is visible but the coolant level is not at the COLD
FILL line, add a 50/50 mixture of clean, drinkable
water and DEX-COOL
®coolant at the coolant
surge tank, but be sure the cooling system,
including the coolant surge tank pressure cap, is
cool before you do it. SeeEngine Coolant on
page 331for 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 coolant surge tank pressure
cap — even a little — they can come out at
high speed. Never turn the cap when the
cooling system, including the coolant
surge tank pressure cap, is hot. Wait for
the cooling system and coolant surge
tank pressure cap to cool if you ever have
to turn the pressure cap.

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. 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, add more of the proper DEX-COOL
®
coolant mixture to the coolant surge tank
until the level reaches the COLD FILL line.
5. Then replace the pressure cap. Be sure the
pressure cap is hand-tight.Check the level in the surge tank when the cooling
system has cooled down. If the coolant is not
at the proper level, repeat Steps 1 through 3 and
reinstall the pressure cap. If the coolant still is
not at the proper level when the system cools
down again, see your retailer.
Windshield Washer Fluid
What to Use
When you need windshield or rear window
washer uid, be sure to read the manufacturer’s
instructions before use. If you will be operating
your vehicle in an area where the temperature may
fall below freezing, use a uid that has sufficient
protection against freezing.

At Each Fuel Fill
It is important to perform these underhood checks
at each fuel ll.
Engine Oil Level Check
Check the engine oil level and add the proper oil
if necessary. SeeEngine Oil on page 318for
further details.
Notice:It is important to check the engine
oil regularly and keep it at the proper level.
Failure to keep the engine oil at the proper level
can cause damage to the engine not covered
by your warranty.
Engine Coolant Level Check
Check the engine coolant level and add
DEX-COOL®coolant mixture if necessary. See
Engine Coolant on page 331for further details.
Windshield Washer Fluid Level Check
Check the windshield washer uid level in
the windshield washer uid reservoir and add
the proper uid if necessary.
At Least Once a Month
Tire Ination Check
Inspect your vehicle’s tires and make sure they
are inated to the correct pressures. Do not forget
to check the spare tire. SeeInation - Tire
Pressure on page 374. Check to make sure the
spare tire is stored securely. SeeChanging a Flat
Tire on page 386.
Tire Wear Inspection
Tire rotation may be required for high mileage
highway drivers prior to the Engine Oil Life System
service notication. Check the tires for wear
and, if necessary, rotate the tires. SeeTire
Inspection and Rotation on page 375.
