To Check  Coolant 
When your engine is cold,  the  coolant  level  should be at 
the FULL COLD mark,

If this  light  comes on,

To Add Coolant 
If you need  more  coolant,  add the  proper  mix at the 
surge tank, but only when the  engine is cool. 
When  replacing  the pressure cap,  make  sure  it  is  tight. 
Surge Tank Pressure Cap 
NOTICE: 
Your  pressure  cap is  an 18 psi (124 kPa) 
pressure-type  cap  and  must  be  tightly  installed  to 
prevent  coolant  loss  and  possible  engine  damage 
from  overheating. 
%%en  you  replace your surge tank pressure  cap, a GM 
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. 
Power Steering Fluid 
p .w ii 
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  at the FULL COLD mark.  Add 
enough  fluid  to bring the  level up to the mark. 
A fluid loss in this system  could  indicate  a problem. 
Have  the system inspected  and repaired. 
What to Add 
Refer to the Maintenance  Schedule  to determine what 
kind 
of fluid  to  use. See “Recommended Fluids  and 
Lubricants” 
in the Index. 
I NOTICE: 
When  adding  power  steering  fluid  or  making  a 
complete  fluid  change,  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. 
To Add 
Open the cap labeled 
WASHER 
FLUID OmY. 
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 
3/4 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  Master  Cylinder 
Your brake master  cylinder 
is here. It is filled  with 
DOT-3  brake fluid. 
There  are  only two reasons why the brake  fluid 
level in 
your  master  cylinder  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.

What  to Add 
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. 
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). NOTICE: 
0 Don’t  let  someone  put in  the  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. 
I NOTICE: 
Continuing  to  drive  with  worn-out  brake pads 
could  result  in  costly  brake repair. 
6-27  
     
        
        Page 238 of 340

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  retailer  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 moderate brake stop, your  disc 
brakes adjust  for wear.  If  you rarely  make a moderate  or 
heavier  stop, then your brakes might  not adjust correctly. 
If  you  drive 
in that way,  then -- very carefully -- make 
a  few  moderate brake 
stops about  every 1,000 miles 
( 1600 
6-28 
km), so your brakes will  adjust properly.  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 wear down and you 
have  to have  new ones  put in 
-- be  sure  you get new 
genuine 
GM replacement parts.  If you don’t, your 
brakes  may no longer  work properly.  For  example, if 
someone  puts in brake linings that  are wrong  for  your 
vehicle, the  balance between  your  front  and rear brakes 
can  change 
-- for the worse.  The braking  performance 
you’ve  come to expect  can  change  in many  other ways  if 
someone  puts in the wrong  replacement  brake  parts. 
Battery 
Every new Oldsmobile has a  Delco  Freedom@ battery. 
You  never have to  add water to  one of these. When  it’s 
time  for  a new battery, we recommend  a  Delco 
Freedom@  battery. Get  one that 
has the replacement 
number shown on the original battery’s label.

Vehicle Storage 
If you’re  not going to drive  your  vehicle  for 25 days or 
more, take  off the  black,  negative (-) cable  from  the 
battery.  This will help  keep  your battery 
from running 
down. 
Contact  your  retailer to learn how to prepare  your 
vehicle  for  longer  storage  periods.
