Cooling System
When it is safe lift the hood:
A. Electric Engine Cooling Fans
B. Pressure Cap
C. Engine Coolant Recovery Tank{CAUTION
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.
{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.
Engine Coolant
The coolant in the vehicle should
last for ve years or 150,000 miles
(240 000 km), whichever occurs
rst. When coolant is added
or changed, use DEX-COOL
®
coolant.
The following explains the cooling
system and how to add coolant when
it is low. If there is a problem with
engine overheating, seeEngine
Overheating on page 9-22Engine
Overheating.
What to Use
Use a 50/50 mixture of clean,
drinkable water and DEX-COOL®
coolant, which will not damage
aluminum parts. If this coolant
mixture is used, nothing else
needs to be added.
9-18 Vehicle Service and Care
2009 - Pontiac Vibe Owner Manual

{CAUTION
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 would not
get the overheat warning. The
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: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.Notice:If you use extra
inhibitors and/or additives in
your vehicle’s cooling system,
you could damage your vehicle.
Use only the proper mixture of
the engine coolant listed in this
manual for the cooling system.
SeePart D: Recommended Fluids
and Lubricants on page 11-18for
more information.
Gives freezing protection down to
−34°F (−38°C).
Gives boiling protection up to
265°F (129°C).
Protects against rust and
corrosion.
Helps keep the proper engine
temperature.
Lets 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 enginecoolant may require changing
sooner, at 30,000 miles
(50 000 km) or 24 months,
whichever occurs rst. Any
repairs would not be covered by
the vehicle warranty. Always
use DEX-COOL (silicate-free)
coolant in your vehicle.
Checking Coolant
The vehicle must be on a level
surface. When the engine is cold,
the coolant level should be at LOW,
or a little higher. When the engine
is warm, the level should be up to
FULL, or a little higher. If it is not,
there could be a leak at the pressure
cap or in the radiator hoses, heater
hoses, radiator, water pump, or
somewhere else in the cooling
system.

How to Add Coolant to the
Coolant Recovery Tank
If you need more coolant, add the
proper DEX-COOL®coolant mixture
at the coolant recovery tank, but
be careful not to spill it.
Occasionally check the coolant level
in the radiator. For information on
how to add coolant to the radiator,
seeCooling System on page 9-18
Cooling System.
{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.
{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

CAUTION (Continued)
you or others could be burned.
Use a 50/50 mixture of clean,
drinkable water and a proper
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.
How to Add Coolant to the
Radiator
When the coolant in the coolant
recovery tank is at the FULL mark,
start the vehicle.
If the overheat warning continues,
there is one more thing that can
be done. Add the proper coolant
mixture directly to the radiator but
be sure the cooling system is
cool before you do it.

4. Then ll the coolant recovery
tank to the FULL mark.
5. Put the cap back on the coolant
recovery tank, but leave the
pressure cap off.
6. Start the engine and let it run
until you can feel the upper
radiator hose getting hot. Watch
out for the engine cooling fan.
7. By this time, the coolant level
inside the radiator ller neck may
be lower. If the level is lower,
add more of the proper coolant
mixture through the ller neck
until the level reaches the base
of the ller neck.
8. Then 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 the ears
on the pressure cap are in
line with the vent tube.Pressure Cap
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.
SeeEngine Compartment Overview
on page 9-6for more information
on location.
Engine Overheating
A coolant temperature gage is
located on the vehicle’s instrument
panel. SeeEngine Coolant
Temperature Gage on page 4-19.
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, the vehicle
needs service.If no problem is apparent, but the
coolant level is not at or above the
FULL mark, add a 50/50 mixture
of clean, drinkable water and
DEX-COOL
®coolant at the coolant
recovery tank. SeeEngine Coolant
on page 9-18for more information
about the proper coolant mixture.
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.

If Steam Is Coming From Your
Engine
{CAUTION
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 re. You or others
could be badly burned. Stop your
engine if it overheats, and get out
of the vehicle until the engine
is cool.Notice:If the engine catches re
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 No Steam Is Coming From
Your Engine
If an engine overheat warning is
displayed but steam is not heard or
seen escaping, 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, try this for
a minute or so:
1. 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.
2. Turn on the heater to full hot at
the highest fan speed and open
the windows as necessary.
If the overheat warning is no longer
displayed, the vehicle can be driven.
Just to be safe, drive slower for about
10 minutes. If the warning does not
come back on, continue to drive.
If the warning continues, pull over,
stop, and park the vehicle right away.
If there is still no sign of steam, idle
the engine for three minutes while
the vehicle is parked. If the warning
is still displayed, turn off the engine
and get everyone out of the vehicle
until it cools down.

Following Distance
Stay at least twice as far behind the
vehicle ahead as you would when
driving your vehicle without a trailer.
This can help you avoid situations
that require heavy braking and
sudden turns.
Passing
More distance in front is needed to
pass when towing a trailer. And,
because the tow vehicle and trailer
are longer, you will need to go
farther beyond the passed vehicle
before you can return to your lane.
Backing Up
Hold the bottom of the steering
wheel with one hand. Then, to move
the trailer to the left, just move that
hand to the left. To move the trailer
to the right, move your hand to the
right. Always back up slowly and, if
possible, have someone guide you.
Making Turns
Notice:Making very sharp turns
while trailering could cause
the trailer to come in contact with
the vehicle. The vehicle could
be damaged. Avoid making very
sharp turns while trailering.
When you are turning with a trailer,
make wider turns than normal.
Do this so your trailer will not strike
soft shoulders, curbs, road signs,
trees or other objects. Avoid jerky or
sudden maneuvers. Signal well in
advance.
Turn Signals When Towing a
Trailer
When you tow a trailer, your vehicle
may need a different turn signal
asher and/or extra wiring. Check
with your dealer/retailer. The arrows
on the instrument panel ash
whenever you signal a turn or lane
change. Properly hooked up, the
trailer lamps also ash, telling other
drivers you are about to turn, change
lanes or stop.When towing a trailer, the arrows
on the instrument panel will ash for
turns even if the bulbs on the trailer
are burned out. Thus, you may think
drivers behind you are seeing your
signal when they are not. It is
important to check occasionally to be
sure the trailer bulbs are still working.
Driving On Grades
Reduce speed and shift to a lower
gearbeforeyou start down a long or
steep downgrade. If you do not shift
down, you might have to use your
brakes so much that they would get
hot and no longer work well.
On a long uphill grade, shift down
and reduce your speed to around
45 mph (70 km/h) to reduce the
possibility of the engine and the
transmission overheating.

Parking on Hills
{CAUTION
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 at surface.
To park your rig on a hill:
1. Apply your regular brakes, but
do not shift into P (Park) for an
automatic transmission or into
gear for a manual transmission,
yet. When parking uphill, turn
your wheels away from the curb.
When parking downhill, turn your
wheels into the curb.
2. Have someone place chocks
under the trailer wheels.3. When the chocks are in place,
release the regular brakes until
the chocks absorb the load.
4. Reapply the regular brakes.
Then apply your parking
brake and shift into P (Park)
for an automatic transmission
or R (Reverse) for a manual
transmission.
5. Release the regular brakes.
When You Are Ready to Leave
After Parking on a Hill
1. Apply your regular brakes and
hold the pedal down while you:
start your engine
shift the transmission
into 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
Your vehicle will need service more
often when you are pulling a trailer.
See the Maintenance Schedule
for more on this. Things that are
especially important in trailer
operation are automatic transmission
uid (do not overll), engine oil, drive
belt, cooling system and brake
system. Each of these is covered in
this manual, and the Index will help
nd them quickly. If you are trailering,
it is a good idea to review this
information before starting your trip.
Check periodically to see that all
hitch nuts and bolts are tight.
Engine Cooling When Trailer
Towing
The cooling system could
temporarily overheat during severe
operating conditions. SeeEngine
Overheating on page 9-22.
