engine OLDSMOBILE BRAVADA 1994 Repair Manual

Let the warning lights and gages work
What to Use
Use a mixture of one-half clean water
(preferably distilled) and one-half
antifreeze that meets
“GM Specification
6038-M,” which won’t damage
aluminum parts. If you use this mixture,
you don’t need
to add anything else.
as
they should.
NOTICE:
If you use an improper coolant mix,
your engine could overheat and be
badly damaged. The repair cost
wouldn’t be covered by your
warranty. Too much water in the
mix can freeze and crack the
engine, radiator, heater core and
other parts.
Some conditions, such as air trapped in
the cooling system, can affect the
coolant level in the radiator. Check the
coolant level when the engine is cold
and follow the steps under
Adding
Coolant for the proper way to add
coolant.
If you have to add coolant more than
four times a year, have your dealer
check your cooling system.
NOTICE:
If you use the proper coolant, you
don’t have to add extra inhibitors
or additives which claim to improve
the system. These can be harmful.
~~
Adding Coolant
To Check Coolant
When your engine is cold, the coolant
level should be at
ADD, or a little
higher. When your engine is warm, the
level should be up to
FULL HOT, or a
little higher.

To Add Coolant
If you need more coolant, add the proper
mix
at the coolant recovery tank.
Add coolant mix at the recovery tank,
but be careful not
to spill it.
I Radiator Pressure Cap
NOTICE:
Your radiator cap is a 15 psi
(105 1tPa) pressure-type cap and
must be tightly installed
to prevent
coolant
loss and possible engine
damage from overheating. Be sure
the arrows on the cap line up with
the overflow tube
on the radiator
filler neck.
When you replace your radiator
pressure cap, an AC@ cap
is
recommended.
Thermostat
Engine coolant temperature is
controlled by a thermostat in the engine
coolant system. The thermostat stops
the flow
of coolant through the radiator
until the coolant reaches a preset
temperature.
When you replace your thermostat, an
AC@ thermostat is recommended.
I Power Steering Fluid
How To Check Power Steering
Fluid
Unscrew the cap and wipe the dipstick
with a clean rag. Replace the cap and
completely tighten it. Then remove the
cap again and look at the fluid level on
the dipstick.
. When the engine compartment is hot,
the level should be
at the HOT mark.
When the engine compartment is
cool, the level should be at the
FULL
COLD mark.

wrong kind of fluid. 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.
Brake fluid can damage paint, so
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 Oldsmobile has front disc brakes
and rear
drum 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).
I NOTICE:
I
Continuing to drive with worn-out
brake pads could result in costly
brake repair.
Some driving conditions or climates
may cause a brake squeal when the
brakes are first applied or lightly
applied. This does not mean something
is wrong with your brakes.
Your rear
drum brakes don’t have wear
indicators, but if you ever hear a rear
brake rubbing noise, have the rear brake
linings inspected.
Also, the rear brake
drums should be removed and
inspected each time the tires are
removed for rotation or changing. When you
have the front brakes replaced,
have the rear brakes inspected, too.
Brake linings should always be replaced
as complete axle sets.
Brake Pedal Travel
See your dealer if the brake pedal does
not return
to normal height, or if there
is a rapid increase in pedal travel.
This
could be a sign of brake trouble.
Brake Adjustment
Every time you make a brake stop, your
disc brakes adjust for wear.
If your brake pedal goes down farther
than normal, your rear drum brakes
may need adjustment. Adjust them by
backing up and firmly applying the
brakes a few times.
Replacing Brake System Parts
The braking system on a modern vehicle
is complex. Its many parts have to be of
top quality and work well together
if the
vehicle is to have really good braking.
Vehicles we design and test have top-
quality
GM brake parts in them, as your
Oldsmobile does when it is new. When
you replace parts
of your braking system
- for example, when your brake linings 179

Payload
The Payload Capacity is shown on the
Certificationflire label. This is the
maximum load capacity that your
vehicle can carry. Be sure to include the
weight of the people inside as part of
your load. If you added any accessories
or equipment after your vehicle left the
factory, remember to subtract the weight
of these things from the payload.
Your dealer can help you with this.
Trailering Package
If your vehicle comes with the trailering
package, there is also a load rating
which includes the weight of the vehicle
and the trailer it tows. This rating is
called the Gross Combination Weight
Rating (GCWR)
.
When you weigh your trailer, be sure to
include the weight of everything you put
in it. And, remember to figure the weight
of the people inside as part
of your load.
Your dealer can help you determine
your GCWR.
Add-on Equipment
When you carry removable items, you
may need to put a limit on how many
people you carry inside your vehicle. Be
sure to weigh your vehicle before you
buy and install the new equipment.
NOTICE:
Your warranty doesn’t cover parts
or components that fail because of
overloading.
I Single Belt Accessory Drive
Your new vehicle uses a serpentine belt
that is lighter, more durable and fuel
efficient than systems with several belts.
The belt runs over or around the pulleys
on the engine.
A tensioner is used to
keep the belt tight at all times. The
tensioner also makes replacing the belt
easier.
If you need to replace the belt, be
sure to get the correct replacement belt.
Your dealership or parts supplier can
help you with this. The Accessory Drive
Belt Routing label on your vehicle will
show you how to route the belt your
vehicle uses.
I Air Conditioning
Every now and then have your
dealership check your air conditioning
system to be sure it has not lost any
cooling ability. If you think the system
is not working properly, have your
dealership check it out as soon as
possible.
The air conditioning will not work when
the temperature is below
40°F (4°C).

blotchy, ringlet-shaped discolorations, and small irregular dark spots etched
into the paint surface.
Although no defect in the paint job
causes this, Oldsmobile

no charge to the owner, the surfaces of
new vehicles damaged by this fallout
condition within 12 months or 12,000
miles (20
000 km) of purchase,
whichever comes first.
Vehicle Identification
Number (UN)
This is the legal identifier for your
Oldsmobile. It appears on a plate in the
front corner of the instrument panel, on
the driver’s side. You can see it if you
look through the windshield from
outside your vehicle. The VIN
also
appears on the Vehicle Certification and
Service
Parts labels and the certificates
of title and registration.
Engine ldentification
The eighth character in your VIN is the
engine code. This code will help you
identify your engine, specifications, and
replacement parts.

“Section C: Periodic Maintenance
Inspections” explains important
inspections that your Oldsmobile
dealer’s service department or another
qualified service center should perform.
“Section
D: Recommended Fluids &
Lubricants” lists some products GM
recommends to help keep your vehicle
properly maintained. These products, or
their equivalents, should be used
whether you do the work yourself or
have it done.
“Section
E: Maintenance Record”
provides a place for you to record the
maintenance performed on your vehicle.
Whenever any maintenance is
performed, be sure to write it down in
this section.
This will help you
determine when your next maintenance
should be done. In addition, it is a good
idea to keep your maintenance receipts.
They may be needed to qualify your
vehicle for warranty repairs.

Using Your Maintenance
Schedules
This section tells you the maintenance
