coolant level PONTIAC SOLSTICE 2007 Owners Manual

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.
Notice:Driving with the low coolant warning
light on could cause your vehicle to overheat.
See “Engine Overheating” underEngine
Coolant on page 257. Your vehicle could be
damaged and the damages might not be
covered by your warranty.
SeeEngine Coolant on page 257for information
on what to do. Your vehicle should be serviced as
soon as possible.
Malfunction Indicator Lamp
Check Engine Light
Your vehicle has a
computer which
monitors operation of
the fuel, ignition,
and emission control
systems.
This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended
to assure that emissions are at acceptable
levels for the life of the vehicle, helping to produce
a cleaner environment. The check engine light
comes on to indicate that there is a problem and
service is required. Malfunctions often will be
indicated by the system before any problem is
apparent. This may prevent more serious damage
to your vehicle. This system is also designed to
assist your service technician in correctly
diagnosing any malfunction.

Checking Engine Oil
It is a good idea to check the engine oil every time
you get fuel. In order to get an accurate reading,
the oil must be warm and the vehicle must be
on level ground.
The engine oil dipstick handle is a yellow loop.
SeeEngine Compartment Overview on page 244
for the location of the engine oil dipstick.
1. Turn off the engine and give the oil several
minutes to drain back into the oil pan. If you
do not do this, the oil dipstick might not
show the actual level.
2. Pull the dipstick and clean it with a paper
towel or cloth, then push it back in all the
way. Remove it again, keeping the tip down
and check the level.

Checking Coolant
The coolant surge tank is located in the engine
compartment on the driver’s side of the vehicle.
SeeEngine Compartment Overview on page 244
for 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.
Do not overll the surge tank. Too much coolant
can result in an overow condition when the uid
is hot.

A. Coolant Surge Tank and Pressure Cap
B. Electric Engine Cooling Fan (Out of View)
{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.
2.0L L4 Engine
263

The coolant level should be at the COLD FILL line.
If it is not, you may have a leak at the pressure cap
or in the radiator hoses, heater hoses, radiator,
water pump, or somewhere 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.
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
are running. If the engine is overheating, the fan
should be running. If they are not, your vehicle
needs service.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:Your engine has a specic cooling
system drain and ll procedure. Failure
to follow this procedure could cause your
engine to overheat and be severely damaged.
If your engine’s cooling system needs to
be drained and re-lled, please see your dealer.
If you have not found a problem yet, check to
see if coolant is visible in the coolant surge tank.
264

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 257for more information.
If no coolant is visible in the coolant surge tank,
add coolant as follows:
{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.
{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 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.
265

3. Fill the coolant surge tank with the proper
mixture, to the COLD FILL line. Wait about
ve minutes, then check to see if the level is
below the COLD FILL line. If the level is
below the line, add additional coolant to bring
the level up to the line. Repeat this procedure
until the level remains constant at the
COLD FILL line for at least ve minutes.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 than the COLD FILL line, add more of
the proper 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 and fully seated.
See your dealer, if necessary.

Part B: Owner Checks and Services
Listed in this part are owner checks and services
which should be performed at the intervals
specied to help ensure the safety, dependability
and emission control performance of your
vehicle.
Be sure any necessary repairs are completed at
once. Whenever any uids or lubricants are added
to your vehicle, make sure they are the proper
ones, as shown in Part D.
At Each Fuel Fill
It is important for you or a service station attendant
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 247for
further details.
Engine Coolant Level Check
Check the engine coolant level and add
DEX-COOL®coolant mixture if necessary. See
Engine Coolant on page 257for 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. SeeWindshield
Washer Fluid on page 269for further details.
At Least Once a Month
Tire Inspection and Ination Check
Visually inspect your vehicle’s tires for wear
and make sure they are inated to the correct
pressures. SeeInation - Tire Pressure
on page 292.
