2003 Oldsmobile Bravada engine oil

If you get the overheat warning with no sign of steam,
try this for a minute or
so:
1. In heavy traffic, let the engine idle in neutral while
stopped.
If it is safe to do so, pull off the road, shift
to
PARK (P) or NEUTRAL (N) and let the
engine idle.
speed and open the window as necessary.
If you no longer have the overheat warning, you can
drive. Just to be safe, drive slower for about
10 minutes.
If the warning doesn’t come back on, you can drive
normally.
If the warning continues and you have not stopped, pull
over, stop, and park your vehicle right away.
2. Turn on your heater to full hot at the highest fan
If there’s still no sign of steam, you can push down the
accelerator until the engine speed
is about twice as
fast as normal idle speed for at least three minutes while
you’re parked.
If you still have the warning, turn off
the engine and get everyone out of the vehicle until it
cools down.
You may decide not to lift the hood but to get service
help right away.
Cooling System
When you decide it’s safe to lift the hood, here’s what
you’ll see:
A. Coolant Recovery Tank
B. Radiator Pressure Cap
C. Engine Fan
If the coolant inside the coolant recovery tank is boiling,
don’t do anything else until it
cools down. The vehicle
should be parked on a level surface.

How to Add Coolant to the Coolant
Recovery Tank
If you haven’t found a problem yet, but the coolant level
isn’t at the FULL COLD mark, add a
50/50 mixture of
clean, drinkable water and DEX-COOL@ engine coolant
at the coolant recovery tank. See
Engine Coolant on
page 5-22 for more information.
water to your cooli
-
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 wouldn’t get the overheat warning.
Your engine could catch fire 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. You
can be burned
.. jou spill coolant on hot
engine parts. Coolant contains ethylene glycol
and
it will burn if the engine parts are hot
enough. Don’t spill coolant on a hot engine.
When the coolant in the coolant recovery tank is at the
FULL COLD mark, start your vehicle.

What to Add Notice:
When you do need brake fluid, use only DOT-3 brake
fluid. Use new brake fluid from a sealed container only. See
Part D: Recommended Fluids and Lubricants
on page 6- 17.
Always clean the brake fluid reservoir cap and the area
around the cap before removing it. This will help
keep dirt )m en’
. the reservoir.
A I:
With the wrong kind of fluid in your brake
system, your brakes may not work well, or
they may not even work at all. This could
cause a crash. Always use the proper brake
fluid.
Using the wrong fluid can badly damage brake
system parts. For example, just a few drops of
mineral-based oil, such as engine oil,
in your
brake system can damage brake system parts
so badly that they’ll have to be replaced.
Don’t let someone put in the wrong kind of fluid
If you spill brake fluid on your vehicle’s painted
surfaces, the paint finish can be damaged. Be
careful not to spill brake fluid on your vehicle. If
you
do, wash it off immediately. See
“Appearance Care’’ in the Index.
Brake Wear
Your vehicle has four-wheel disc brakes.
Disc brake pads have built-in wear indicators that make
a high-pitched warning sound when the brake pads
are worn and new pads are needed. The sound
may come and
go or be heard all the time your vehicle
is moving (except when you are pushing
on the
brake pedal firmly).

Part A: Scheduled Maintenance
Services
This part contains engine oil scheduled maintenance
which explains the engine oil life system and how
it indicates when to change the engine oil and filter.
Also, listed are scheduled maintenance services which
are
to be performed at the mileage intervals specified.
Using Your Maintenance Schedule
We at General Motors want to help you keep your
vehicle in good condition. But we don’t know exactly how
you’ll drive it. You may drive very short distances only
a few times a week. Or you may drive long distances in
very hot, dusty weather. You may use your vehicle in
making deliveries. Or you may drive it to work,
to
do errands or in many other ways.
Because
of all the different ways people use their
vehicles, maintenance needs vary. You may need more
frequent checks and replacements.
So please read
the following and note how you drive.
If you have any
questions on how
to keep your vehicle in good condition,
see your dealer. This part tells you the
maintenance services you should
have done and when you should schedule them.
When you
go to your dealer for your service needs,
you’ll know that GM-trained and supported service
people will perform the work using genuine GM parts.
The proper fluids and lubricants
to use are listed in
Part
D. Make sure whoever services your vehicle uses
these.
All parts should be replaced and all necessary
repairs done before you or anyone else drives the
vehicle.
This schedule is for vehicles that:
carry passengers and cargo within recommended
limits. You will find these limits on your vehicle’s
Certificationflire label. See
Loading Your Vehicle on
page
4-4 1.
are driven on reasonable road surfaces within legal
driving limits.
are driven off-road in the recommended manner.

Operating Your All- Wheel-Drive Vehicle Off
Paved Roads on page 4- 15.
use the recommended fuel. See Gasoline Octane
on page 5-5.

Scheduled Maintenance
The services shown in this schedule up to 100,000 miles
(166 000 km) should be repeated after 100,000 miles
(166 000 km) at the same intervals for the life of
this vehicle. The services shown at
150,000 miles
(240 000 km) should be repeated at the same interval
after
150,000 miles (240 000 km) for the life of this
vehicle.
See
Part B: Owner Checks and Services on page 6- 10
and Part C: Periodic Maintenance Inspections on
page 6- 15.
Footnotes
t The US. Environmental Protection Agency or the
California Air Resources Board has determined that the
failure to perform this maintenance item will not nullify
the emission warranty or limit recall liability prior
to
the completion of the vehicle 's useful life. We, however,
urge that all recommended maintenance services be
performed at the indicated intervals and the
maintenance be recorded.
+ A good time to check your brakes is during tire
rotation. See Brake System Inspection
on page 6- 16.
Engine Oil Scheduled Maintenance
Change engine oil and filter as indicated by the GM
Oil Life System (or every 12 months, whichever
occurs first). Reset the system.
Your vehicle has a computer system that lets you know
when
to change the engine oil and filter. This is
based on engine revolutions and engine temperature,
and not on mileage. Based on driving conditions,
the mileage
at which an oil change will be indicated can
vary considerably. For the
oil life system to work
properly, you must reset the system every time the oil is
changed.
When the system has calculated that oil life has been
diminished, it will indicate that an oil change is
necessary. A CHANGE ENGINE
OIL light will come on.
Change your oil as soon as possible within the next
two times you stop for fuel. It is possible that,
if you are
driving under the best conditions, the oil life system
may not indicate that an oil change is necessary for over
a year. However, your engine oil and filter must be
changed at least once a year and at this time the system
must be reset.
It is also important to check your oil
regularly and keep
it at the proper level.
If the system is ever reset accidentally, you must
change your oil at
3,000 miles (5 000 km) since your
last oil change. Remember
to reset the oil life system
whenever the oil is changed. See
Engine Oil on
page 5-13 for information on resetting the system.
After the services are performed, record the date, odometer reading and who performed the service on the
maintenance record pages in Part
E of this schedule.
An Emission Control Service.

vehicle, make sure they are the proper ones, as shown
in Part
D.
At Each Fuel Fill
