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.

coolant recovery tank.

{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.

Part B: Owner Checks
and Services
These owner checks and services
should be performed at the intervals
specied to help ensure vehicle
safety, dependability, and emission
control performance.
Be sure any necessary repairs are
completed at once. Whenever
any uids or lubricants are added to
the vehicle, make sure they are
the proper ones, as shown in Part D.
At Each Fuel Fill
It is important to perform these
underhood checks at each fuel fill.
Engine Oil Level Check
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 the vehicle
warranty.Check the engine oil level and add
the proper oil if necessary. See
Engine Oil on page 9-9.
Engine Coolant Level Check
Check the engine coolant level
and add DEX-COOL®coolant
mixture if necessary. SeeEngine
Coolant on page 9-18.
Windshield Washer Fluid
Level Check
Check the windshield washer uid
level in the windshield washer
uid reservoir and add the proper
uid if necessary. SeeWindshield
Washer Fluid on page 9-24.
Hood Latch Operation Check
Pull the primary hood latch release
handle inside the vehicle. The
secondary latch should keep the
hood from opening all the way when
the primary latch is released. Make
sure the hood closes rmly.
SeeHood Release on page 9-5.
11-12 Service and Maintenance
2009 - Pontiac Vibe Owner Manual

Engine Cooling System
Inspection
Inspect the hoses and have them
replaced if they are cracked, swollen
or deteriorated. Inspect all pipes,
ttings and clamps; replace as
needed. Clean the outside of the
radiator and air conditioning
condenser. To help ensure proper
operation, a pressure test of
the cooling system and pressure
cap is recommended at least once
a year.
Throttle System
Inspection
Inspect the throttle system for
interference or binding, and for
damaged or missing parts.
Replace parts as needed.
Replace any components that
have high effort or excessive wear.
Do not lubricate accelerator and
cruise control cables.
Brake System Inspection
Inspect the complete system.
Inspect brake lines and hoses for
proper hook-up, binding, leaks,
cracks, chang, etc. Inspect disc
brake pads for wear and rotors for
surface condition. Inspect other
brake parts, including calipers,
parking brake, etc. You may need
to have your brakes inspected more
often if your driving habits or
conditions result in frequent braking.
