2010 SATURN VUE engine overheat

Driving and Operating 9-55
Turn Signals When Towing a
Trailer
The turn signal indicators on the
instrument panel flash whenever
signaling a turn or lane change.
Properly hooked up, the trailer
lamps also flash, telling other
drivers the vehicle is turning,
changing lanes or stopping.
When towing a trailer, the arrows on
the instrument panel flash for turns
even if the bulbs on the trailer are
burned out. Check occasionally to
be sure the trailer bulbs are still
working.
Driving On Grades
Reduce speed and shift to a
lower gear before starting down a
long or steep downgrade. If the
transmission is not shifted down, the
brakes might have to be used so
much that they would get hot and no
longer work well.
The vehicle can tow in D (Drive).
Use a lower gear if the transmission
shifts too often.When towing at high altitude on
steep uphill grades, engine coolant
will boil at a lower temperature than
at normal altitudes. If the engine is
turned off immediately after towing
at high altitude on steep uphill
grades, the vehicle may show signs
similar to engine overheating. To
avoid this, let the engine run while
parked, preferably on level ground,
with the transmission in P (Park) for
a few minutes before turning the
engine off. If the overheat warning
comes on, see
Engine Overheating
on page 10‑20.
Parking on Hills
{WARNING
Parking the vehicle on a hill with
the trailer attached can be
dangerous. If something goes
wrong, the rig could start to move.
People can be injured, and both
the vehicle and the trailer can be
damaged. When possible, always
park the rig on a flat surface. If parking the rig on a hill:
1. Press the brake pedal, but do
not shift into P (Park) yet. Turn
the wheels into the curb if facing
downhill or into traffic if facing
uphill.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the brake pedal
until the chocks absorb the load.
4. Reapply the brake pedal. Then apply the parking brake and shift
into P (Park).
5. Release the brake pedal.

9-56 Driving and Operating
Leaving After Parking on a Hill
1. Apply and hold the brake pedalwhile you:
.Start the engine.
.Shift into a gear.
.Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer
Towing
The vehicle needs service more
often when pulling a trailer. See this
manual's Maintenance Schedule or
Index for more information. Things
that are especially important in
trailer operation are automatic transmission fluid, engine oil, axle
lubricant, belts, cooling system and
brake system. Inspect these before
and during the trip.
Check periodically to see that all
hitch nuts and bolts are tight.
Engine Cooling When Trailer
Towing
The cooling system may temporarily
overheat during severe operating
conditions. See
Engine Overheating
on page 10‑20.
Trailer Towing
Three important considerations
have to do with weight:
.The weight of the trailer
.The weight of the trailer tongue
.The total weight on the vehicle's
tires
Weight of the Trailer
How heavy can a trailer safely be?
Speed, altitude, road grades,
outside temperature, special
equipment, and the amount of
tongue weight the vehicle can carry
must be considered. See “Weight of
the Trailer Tongue” later in this
section for more information.
Maximum trailer weight is calculated
assuming only the driver is in the
tow vehicle and it has all the
required trailering equipment. The
weight of additional optional
equipment, passengers and cargo in
the tow vehicle must be subtracted
from the maximum trailer weight.

Cooling System
When it is safe to lift the hood:
2.4L L4 Engine shown, 3.5L V6 and3.6L V6 Engines similar
A. Electric Engine Fan
B. Coolant Surge Tank
C. 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.
If the coolant inside the coolant
surge tank is hot, do not do anything
else until it cools down. The vehicle
should be parked on a level surface.
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 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.

Vehicle Care 10-15
Notice:Engine damage from
running the engine without
coolant is not covered by the
warranty.
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 your vehicle
is filled with DEX-COOL®engine
coolant. This coolant is designed to
remain in your vehicle for five years
or 240 000 km (150,000 miles),
whichever occurs first, if you add
only DEX-COOL
®extended life
coolant.
The following explains your cooling
system and how to add coolant
when it is low. If you have a problem
with engine overheating, see Engine
Overheating on page 10‑20.
A 50/50 mixture of clean, drinkable
water and DEX-COOL
®coolant will:
.Give freezing protection down
to −37°C (−34°F).
.Give boiling protection up to
129°C (265°F).
.Protect against rust and
corrosion.
.Help keep the proper engine
temperature.
.Let the warning lights and gages
work as they should.
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.
ProCarManuals.com

10-16 Vehicle Care
What to Use
Use a mixture of one-half clean,
drinkable water and one-half
DEX-COOL
®coolant which will not
damage aluminum parts. If you use
this coolant mixture, you do not
need to add anything else.
{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
(Continued)
WARNING (Continued)
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.
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. If you have to add coolant more
than four times a year, have your
dealer/retailer check your cooling
system.
Notice:
If extra inhibitors and/or
additives are used in the vehicle's
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 11‑7for
more information.

10-18 Vehicle Care
How to Add Coolant to the
Coolant Surge Tank
Notice:This vehicle has a
specific coolant fill procedure.
Failure to follow this procedure
could cause the 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
between the MIN and MAX lines,
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. See Engine Coolant
on
page 10‑15for more information.
{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 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.
{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.
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.

Engine Overheating
There is a coolant temperature
warning light on your vehicle's
instrument panel. SeeEngine
Coolant Temperature Warning Light
on page 5‑21.
If Steam Is Coming From
Your Engine
{WARNING
Steam from an overheated engine
can cause serious injury, even if
the hood is opened just a little.
Stay away from the engine if
steam is seen or heard coming
from it. Just turn it off and get
everyone away from the vehicle
(Continued)
WARNING (Continued)
until it cools down. Wait until there
is no sign of steam or coolant
before opening the hood.
If driving continues when the
engine is overheated, the liquids
in it can catch fire. Someone
could get badly burned. Stop the
engine if it overheats, and get out
of the vehicle until the engine has
cooled.
Notice: Driving the vehicle when
there is no coolant in the coolant
overflow recovery bottle, can
badly damage the engine.
The costly repairs would not be
covered by the vehicle warranty.
If No Steam Is Coming From
The Engine
If there is an engine overheat
warning, 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 there is an overheat warning with
no sign of steam, try this for a
minute or so:
1. If there is an air conditioner and it is on, turn it off.
2. Turn on the heater to full hot at the highest fan speed and open
the windows as necessary.
3. Try to minimize engine load. If in a traffic jam, shift to N (Neutral);
otherwise, shift to the highest
gear possible while driving.
