2008 SATURN ASTRA engine oil

A 50/50 mixture of clean, drinkable
water and DEX-COOL®coolant will:
Give freezing protection down
to−34°F (−37°C).
Give boiling protection up to
265°F (129°C).
Protect against rust and
corrosion.
Help keep the proper engine
temperature.
Let 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 engine
coolant may require changing
sooner, at the rst maintenance
service after each 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 the vehicle.
What to Use
Use a mixture of one-half clean,
drinkable water and one-half
DEX-COOL
®coolant which will not
damage aluminum parts. If you
use this coolant mixture, you do not
need to add anything else.
{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. See Recommended
Fluids and Lubricants in the
Maintenance and Limited
Warranty and Owner Assistance
Information manual.

{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.
If the coolant inside the coolant
reservoir is boiling, do not do
anything else until it cools down.
The vehicle should be parked on a
level surface.
The coolant level should be at or
above the KALT/COLD mark on the
coolant reservoir. If it is not, you
may have a leak at the coolant
reservoir pressure cap or in
the radiator hoses, heater hoses,
radiator, water pump, or somewhere
else 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 fans are
running. If the engine is overheating,
both fans should be running.
If they are not, your vehicle needs
service.Notice:Engine damage from
running the engine without
coolant is not covered by the
warranty.
Notice:Using coolant other
than DEX-COOL
®can 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 the vehicle warranty. Always
use DEX-COOL
®(silicate-free)
coolant in the vehicle.

How to Add Coolant to the
Coolant Reservoir
Notice:This vehicle has a
specic coolant ll procedure.
Failure to follow this procedure
could cause the engine to
overheat and be severely
damaged.
If you have not found a problem yet,
check to see if coolant is visible
in the coolant reservoir. If coolant is
visible but the coolant level is not
at or above the KALT/COLD
mark, add a 50/50 mixture of clean,
drinkable water and DEX-COOL
®
coolant at the coolant reservoir,
but be sure the cooling system,
including the coolant reservoir
pressure cap, is cool before you
do it. SeeEngine Coolant on
page 9-12for more information.If no coolant is visible in the coolant
reservoir, 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
reservoir pressure cap — even
a little — they can come out at
high speed. Never turn the cap
when the cooling system,
including the coolant reservoir
pressure cap, is hot. Wait for
the cooling system and coolant
reservoir pressure cap to cool
if you ever have to turn the
pressure cap.
{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
you 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: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.

Required Services” in the Limited
Warranty, Maintenance and
Owner Assistance Information
manual. Use new brake uid
from a sealed container only.
See “Recommended Fluids and
Lubricants” in the Limited Warranty,
Maintenance and Owner Assistance
Information manual.
Always clean the brake uid
reservoir cap and the area
around the cap before removing it.
This helps keep dirt from entering
the reservoir.
{CAUTION
With the wrong kind of uid in
the brake hydraulic system,
the brakes might not work well.
This could cause a crash.
Always use the proper brake
uid.Notice:
Using the wrong uid can
badly damage brake
hydraulic system parts.
For example, just a few drops
of mineral-based oil, such
as engine oil, in the brake
hydraulic system can
damage brake hydraulic
system parts so badly that
they will have to be replaced.
Do not let someone put in
the wrong kind of uid.
If you spill brake uid on your
vehicle’s painted surfaces, the
paint nish can be damaged.
Be careful not to spill brake
uid on your vehicle. If you
do, wash it off immediately.
SeeExterior Cleaning on
page 9-75.
Brake Wear
Your vehicle has disc brakes.
Notice:Continuing to drive
with worn-out brake pads could
result in costly brake repair.
Front disc brake pads have built-in
brake pad wear indicators that
make a high-pitched warning sound
when the brake pads are worn
and new pads are needed.
The sound can come and go or be
heard all the time your vehicle is
moving, except when you are
pushing on the brake pedal rmly.
{CAUTION
The brake wear warning sound
means that soon the brakes will
not work well. That could lead
to an accident. When you hear
the brake wear warning sound,
have your vehicle serviced.
