Rear Axle What to Use
When to Check and Change Lubricant
Refer to the Maintenance Schedule to determine how
often to check the lubricant and when to change it. See
“Scheduled Maintenance Services”
in the Index.
How to Check Lubricant
If the level is below the bottom of the filler plug hole,
you’ll need to add some lubricant. Add enough lubricant
to raise the level
to the bottom of the filler plug hole. Refer to the Maintenance
Schedule to determine what
kind of lubricant to use. See “Recommended Fluids and
Lubricants”
in the Index.
Engine Coolant
The cooling system in your vehicle is filled with new
DEX-COOL TM (orange-colored, silicate-free) engine
coolant. This coolant
is designed to remain in your
vehicle for
S years or 100,000 miles (1 66 000 km),
whichever occurs first.
The following explains your cooling system and
how to
add coolant when it is low. If you have a problem with
engine overheating, see “Engine Overheating”
in
the Index.
A SO/SO mixture of water and the proper coolant for
your Oldsmobile
will:
0 Give freezing protection down to -34°F (-37°C).
0 Give boiling protection up to 265°F (129°C).
0 Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as
they should.

NOTICE:
When adding coolant it is important that you use
DEX-COOL
TM (orange-colored, silicate-free)
coolant meeting
GM Specification 6277M.
If silicated coolant is added to the system,
premature engine, heater core or radiator
corrosion may result.
In addition, the engine
coolant will require change sooner
-- at
30,000 miles (50 000 km) or 24 months,
whichever occurs first.
What
to Use
Use a mixture of one-half
clean water (preferably
distilled) and one-half
DEX-COOL TM (orange-colored,
silicate-free) antifreeze that meets
GM Specification
6277M, which won’t damage aluminum parts. Use
GM Engine Coolant Supplement (sealer) (GM Part
No. 3634621) with any complete coolant change. If you
use this mixture, you don’t need to add anything else.
A CAUl ,ON:
Adding only plain water to your cooling system
can be dangerous. Plain water,
or some other
liquid like alcohol, can boil before the proper
coolant mix will. Your vehicle’s coolant warning
system is set for the proper coolant mix. With
plain water or the wrong mix, 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 mix of clean
water and DEX-COOL
TM (orange-colored,
silicate-free) antifreeze.

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.
If you have to add coolant more than four times a year,
have
your retailer check your cooling system.
NOTICE:
If you use the proper coolant, you don’t have to
add extra inhibitors or additives which claim to
imnrove the system. These can be harmful.
Checking 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.

Adding 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.
'hrning the radiator pressure cap when the
engine and radiator are hot can allow steam and
scalding liquids to blow out and burn you badly.
With the coolant recovery tank, you will almost
never have to add coolant at the radiator.
Never turn the radiator pressure cap
-- even a
little 0- when the engine and radiator are hot. 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. Don't spill coolant on
a hot engine.

Radiator Pressure Cap
I
NOTICE:
Your radiator cap is a 15 psi (105 kPa)
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.
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.
Power Steering Fluid
When to Check Power Steering Fluid
It is not necessary to regularly check power steering
fluid unless you suspect there is a leak in the system or
6-23

you hear an unusual noise. A fluid loss in this system
could indicate a problem. Have the system inspected
and repaired.
How To Check Power Steering Fluid
When the engine compartment is cool, 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.
The
level should be between the ADD and FULL marks.
If necessary, add only enough fluid to bring the level up
to the proper range.
What to Use
Refer to the Maintenance Schedule to determine what
kind of fluid to
use. See “Recommended Fluids and
Lubricants’’
in the Index. Always use the proper fluid.
Failure to use the proper fluid can cause leaks and
damage hoses and seals.
Windshield Washer Fluid
What to Use
When you need windshield washer fluid, be sure to read
the manufacturer’s instructions before
use. If you will be
operating your vehicle in an area where the temperature
may fall below freezing, use a fluid
that has sufficient
protection against freezing.
Adding Washer Fluid
Open the cap labeled WASHER FLUID ONLY. Add
washer fluid
until the tank is full.

When using concentrated washer fluid,
follow
the manufacturer’s instructions
for
adding water.
Don’t mix water with ready-to-use washer
fluid. Water can cause the solution to freeze
and damage your washer fluid tank and
other parts of the washer system. Also,
water doesn’t clean as well as washer fluid.
Fill your washer fluid tank only
three-quarters full when it’s very cold. This
allows for expansion, which could damage
the tank if it is completely full.
Don’t use radiator antifreeze
in your
windshield washer. It can damage your
washer system and paint.
Brakes
Brake Fluid
Your brake master cylinder reservoir is here. It is filled
with DOT-3 brake fluid.
ProCarManuals.com

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 system. If it is, you should have
your brake system fixed, since a leak means that sooner
or later your brakes won’t work well, or won’t work
at all.
So, it isn’t a good idea to “top off’ your brake fluid.
Adding brake fluid won’t correct a leak. If you
add fluid
when your linings are worn, then you’ll have too much
fluid when you get new brake linings.
You should add
(or remove) brake fluid, as necessary, only when work is
done
on the brake hydraulic system.
If you have too much brake fluid, it can spill
on the engine. The fluid will burn
if the engine
is hot enough. You or others could be burned,
and your vehicle could be damaged. Add brake
fluid only when work
is done on the brake
hydraulic system.
Refer to the Maintenance Schedule to determine when to
check your brake fluid. See “Periodic Maintenance
Inspections”
in the Index.
ProCarManuals.com

Checking Brake Fluid What
to Add
You can check the brake fluid without taking off the cap.
Just look at
the windows on the brake fluid reservoir.
The fluid levels should be above MIN. If they aren’t,
have your brake system checked to see if there is a leak.
After work is done on the brake hydraulic system, make
sure the levels are above MIN and below the
top of
each window. When
you do need brake fluid, use only
DOT-3 brake
fluid
-- such as Delco Supreme 11 @ (GM Part
No. 1052535). Use new brake fluid from a sealed
container only, and always clean the brake fluid
reservoir cap before removing it.
A CAUTION:
With the wrong kind of fluid in your brake
system, your brakes may nott work well, or they
may not even work at all. This could cause a
crash. Always use the proper brake fluid.

0 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%
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 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
The brake wear warning sound means that
sooner or later your brakes won’t work well.
That could lead to an accident. When you hear
the brake wear warning sound, have your
vehicle serviced.
