2007 CHEVROLET AVEO engine coolant

How to Add Coolant to the Coolant
Surge Tank
Notice:This vehicle has a specic coolant ll
procedure. Failure to follow this procedure
could cause your 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 between
the Minimum and Maximum marks, 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 287
for more information.If no coolant is visible in the 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.
294

{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 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.
{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.
1. You can remove the coolant surge tank
pressure cap when the cooling system,
including the coolant surge tank pressure cap
and upper radiator hose, is no longer hot.
Turn the pressure cap slowly counterclockwise
about two or two and one-half turns.
If you hear a hiss, wait for that to stop. This
will allow any pressure still left to be
vented out the discharge hose.
295

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 Maximum mark, add
more of the proper mixture to the coolant
surge tank until the level reaches the mark.
5. Then replace the pressure cap. Be sure the
pressure cap is hand-tight and fully seated.
See your dealer, if necessary.Power Steering Fluid
When to Check Power Steering Fluid
The power steering fluid reservoir is located toward
the front of the engine compartment on the driver’s
side of the vehicle. SeeEngine Compartment
Overview on page 276for reservoir location.
It is not necessary to regularly check power
steering fluid unless you suspect there is a leak in
the system or you hear an unusual noise. A
fluid loss in this system could indicate a problem.
Have the system inspected and repaired.
297

Notice:
When using concentrated washer uid,
follow the manufacturer’s instructions
for adding water.
Do not mix water with ready-to-use washer
uid. Water can cause the solution to
freeze and damage your washer uid tank
and other parts of the washer system.
Also, water does not clean as well
as washer uid.
Fill your washer uid tank only
three-quarters full when it is very cold.
This allows for uid expansion if freezing
occurs, which could damage the tank if it is
completely full.
Do not use engine coolant (antifreeze) in
your windshield washer. It can damage
the vehicle’s windshield washer system
and paint.
Brakes
Brake Fluid
Your vehicle has
one reservoir for both
the brake and clutch
hydraulic systems. It is
filled with DOT-3
brake fluid. SeeEngine
Compartment
Overview on page 276
for the location of
the reservoir.
There are only two reasons why the brake fluid
level in the reservoir might go down. The first is that
the brake fluid goes down to an acceptable level
during normal brake lining wear. When new linings
are put in, the fluid level goes back up. The other
reason is that fluid is leaking out of the brake or
clutch system. If it is, you should have the brake/
clutch system fixed, since a leak means that sooner
or later the brakes will not work well.

Part B: Owner Checks and Services
Listed in this part are owner checks and services
which should be performed at the intervals
specified to help ensure the safety, dependability
and emission control performance of your vehicle.
Be sure any necessary repairs are completed at
once. Whenever any fluids 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 fill.
Engine Oil Level Check
Check the engine oil level and add the proper oil
if necessary. SeeEngine Oil on page 277for
further details.
Engine Coolant Level Check
Check the engine coolant level and add the proper
coolant mixture if necessary. SeeEngine Coolant
on page 287for further details.
Windshield Washer Fluid Level Check
Check the windshield washer fluid level in the
windshield washer fluid reservoir and add the
proper fluid if necessary. SeeWindshield Washer
Fluid on page 298for further details.
At Least Once a Month
Tire Ination Check
Inspect the tires and make sure the tires are inflated
to the correct pressures. Do not forget to check the
spare tire. SeeInflation - Tire Pressure on page 326.
At Least Twice a Year
Restraint System Check
Make sure the safety belt reminder light and all
your belts, buckles, latch plates, retractors
and anchorages are working properly. Look for
any other loose or damaged safety belt system
parts. If you see anything that might keep a safety
belt system from doing its job, have it repaired.
Have any torn or frayed safety belts replaced.
Also look for any opened or broken airbag
coverings, and have them repaired or replaced.
(The airbag system does not need regular
maintenance.)
