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 a proper
antifreeze.

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.
I
When the coolant in the coolant
recovery
tank is at or above the FULL
HOT mark, start your vehicle.
If the overheat warning continues,
there’s one more thing you can try. You
can add the proper coolant
mix directly
to the radiator, but be sure the cooling
system is cool before
you do it.

~ I Vow to Add Coolant to the Radiator:
I. You can remove the radiator pressure
cap when the cooling system, including
the radiator pressure cap and upper radiator hose, is no longer hot.
Turn
the pressure cap slowly to the left
until it first stops. (Don’t press down
while turning the pressure cap.)
If you hear a hiss, wait for that to stop.
A hiss means there is still some pressure
left.
2. Then keep turning the pressure cap,
but now push down as you turn it.
Remove the pressure cap.

7. By this time, the coolant level inside
the radiator filler neck may be lower.
If
the level is lower, add more of the
proper
mix through the filler neck
until the level reaches the base
of the
filler neck.
8. Then replace the pressure cap. Be
sure the arrows
on the pressure cap
line up like this.

If You’re Stuck: In Sand, Mud,
Ice or Snow
What you don’t want to do when your
vehicle is stuck is to spin your wheels.
The method known as “rocking” can
help you get out when you’re stuck, but
you must use caution.
‘ If you let your tires spin at
high speed, they can explode
and
you or others could be injured.
And, the transaxle or other parts of
the vehicle can overheat. That could
cause an engine compartment fire
or other damage. When you’re
stuck, spin the wheels as little as
possible. Don’t spin
the wheels
above
35 mph (56 km/h) as shown
on the speedometer.

F$ your transaxle.
Rocking Your Vehicle to Get it Out:
First, turn your steering wheel left and
right. That will clear the area around
your front wheels. Then shift back and
forth between
R (Reverse) and a
forward gear, spinning the wheels as
little as possible. Release the accelerator
pedal while
you shift, and press lightly
on
the accelerator pedal when the
transaxle is
in gear. If that doesn’t get
you out after a few tries, you may need
to be towed out. If you do need to be
towed out, see the
Index- under Towing
Your Oldsmobile.

The following explains your cooling
system and how to add coolant when it
is low.
If you have a problem with
engine overheating, see the
Index under
Engine Overheating.

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

Supplement (sealer) with any complete
coolant change. If you use these, you
don’t need to add anything else.

NOTICE
If you use an improper coolant
mix, your engine could overheat
and be badly damaged. The repail
cost wouldn’t

warranty. Too much water

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 mJLL HOT, or a
little higher.

Radiator Pressure Cap
(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
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.
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.
the level should be at the

/njector 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.
Head/ight 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.
