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
(Continued)
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.

{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
Turning the radiator pressure cap
when the engine and radiator are
hot can allow steam and scalding
liquids to blow out and burn you
badly. With the coolant recovery
tank, you will almost never have
to add coolant at the radiator.
Never turn the radiator pressure
cap — even a little — when the
engine and radiator are hot.
1. Remove the pressure cap when
the cooling system, including the
pressure cap and upper radiator
hose, is no longer hot. Turn
the pressure cap slowly
counterclockwise until it rst
stops. Do not press down while
turning the pressure cap.If you hear a hiss, wait for that
to stop. A hiss means there
is still some pressure left.
2. Keep turning the pressure cap,
but now push down while turning.
Remove the pressure cap.
3. Fill the radiator with the proper
coolant mixture, up to the base
of the ller neck. For more
information about the proper
coolant mixture look earlier in
this section.

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.
