Automatic  Transaxle  Fluid 
When to Check and Change 
A good time to check your  automatic 
transaxle  fluid  level  is  when the engine 
oil  is  changed.  Refer 
to the  Maintenance 
Schedule  to determine  when to change 
your fluid.  See 
Scheduled Maintenance 
Services 
in  the Index. 
How to Check 
Because  this  operation  can be a  little 
difficult,  you may  choose  to have  this 
done  at  an Oldsmobile dealership 
Service  Department. 
If  you  do it yourself, be  sure  to follow 
all  the  instructions  here,  or  you could 
get  a false  reading  on  the dipstick. 
NOTICE: 
Too much or  too  little fluid  can 
damage your  transaxle. 
Too much 
can  mean  that some  of the  fluid 
could come  out  and fall on  hot 
engine  parts  or  exhaust  system, 
starting  a  fire. Be sure  to  get an 
accurate  reading if you  check your 
transaxle  fluid. 
Wait  at least 
30 minutes  before 
checking  the transaxle  fluid  level 
if you 
have  been  driving:

To get the  right reading,  the fluid 
should  be at normal  operating 
temperature,  which is 
180°F to 200°F 
(82°C to 93°C). 
Get the vehicle  warmed  up by driving 
about 
15 miles  (24 ltm) when  outside 
temperatures  are  above 
50°F (10°C). If 
it's colder  than 50°F ( 10°C), you may 
have  to drive longer. 
To  Check  the  Fluid  Level 
Park  your vehicle  on a level  place. 
With  the parking  brake applied,  place

move  the shift  lever  through  each gear 
range,  pausing for  about  three 
seconds  in each  range.  Then, position 
the  shift  lever  in 
P (Park). 
Let the engine  run at idle for  three  to 
five  minutes. 
Then,  Without  Shutting Off the 
Engine,  Follow  these  Steps: 
1. Pull  out  the  dipstick  and wipe  it with 
a  clean  rag or paper towel. 
2. Push  it back  in  all  the way,  wait three 
seconds  and  then  pull  it back out 
again. 
3. Check  both sides of the dipstick,  and 
read  the lower  level.  The fluid  level 
must  be in the  cross-hatched  area. 
4. If the  fluid  level  is  in  the acceptable 
range,  push  the  dipstick back in  all 
the  way.

How to Add Fluid 
Refer to  the  Maintenance  Schedule  to 
determine  what  kind of transaxle  fluid 
to  use.  See 
Recommended  Fluids and 
Lubricants 
in  the Index. 
If the  fluid  level  is  low, add only  enough 
of  the  proper  fluid to bring  the level  into 
the  cross-hatched  area 
on the dipstick. 
1. Pull  out  the  dipstick. 
2. Using a long-neck  funnel:  add 
enough  fluid at  the  dipstick hole  to 
bring  it to  the  proper level. 
It  doesn’t  take  much fluid, generally  less 
than  a  pint 
(OSL). Don’t  overfill. We 
recommend  you  use only  fluid  labeled 
DEXRONo-I11  or DEXRON@-IIE, 
because fluids with  that label  are made 
especially  for your automatic  transaxle. 
Damage  caused by fluid  other  than 
DEXRONo-I11  or DEXRONB-IIE  is  not 
covered  by your  new vehicle  warranty. 
After adding fluid, recheck  the fluid 
level  as described  under 
How to 
Check.

What to Use 
Use a mixture  of one-half clean  water 
(preferably distilled)  and one-half 
antifreeze  that meets 
“GM Specification 
1825-M:” which won’t damage 
aluminum  parts. 
You can also use  a 
recycled  coolant conforming  to

NOTICE: 
198 
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. 
Adding Coolant 
To Check  Coolant 
When  your engine  is cold,  the coolant 
level  should  be at 
COLD, 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. 
Radiator  Pressure  Cap 
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. 
When  you replace  your radiator 
pressure  cap,  an  AC8 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 
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 
H (Hot) 
mark. 
When  the engine  compartment  is 
cool,  the level  should  be  at  the 
C 
(Cold) mark.

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: 
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 apply the brakes 
moderately, with or  without  the vehicle 
moving,  your brakes  adjust for wear.

Injector 3365 Fuse 
(3800 V6 ENGINE ONLY) 
This 20-amp fuse is located  underhood, 
on  a  bracket  just  behind the passenger 
side headlight.  It is mounted  on the  face 
of  the  bracket  in the  position closest  to 
the  passenger side  of the  vehicle.  The 
fuse services  the  injectors,  fuel pump, 
oil  pressure  sender  and  fuel pump 
switch. 
To access  the fuse,  pry back  the  latch 
with  a  screwdriver,  then pull down on 
the  base 
of the  unit.  If you  need  to 
replace  the  fuse,  be  sure  to use  a  20- 
amp  fuse. 
Push the  base  of the  unit  firmly up  into 
the  cover  until  the  latch  snaps  into  the 
locked  position. 
Headlight  Wiring 
The headlight wiring  is protected  by a 
circuit  breaker  in the  light switch.  An 
electrical overload  will cause  the  lights 
to  go  on  and  off: or 
in some cases  to 
remain  off. If this  happens,  have your 
headlight system checked right away. 
Windshield  Wipers 
The windshield wiper  motor is 
protected by a circuit  breaker  and  a 
fuse. 
If the  motor  overheats  due  to 
heavy  snow,  etc.,  the wiper  will stop 
until  the  motor  cools. 
If the overload is 
caused  by some electrical problem, have 
it fixed. 
Power  Windows  and  Other  Power 
Options 
Circuit  breakers  in the  circuit 
breakerhelay  panel protect the power 
windows  and  other  power accessories. 
When  the  current  load is too  heavy,  the 
circuit breaker  opens  and closes, 
protecting  the  circuit until the problem 
is  fixed.
