1994 OLDSMOBILE SILHOUETTE engine overheat

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.
obtained, push the dipstick back in all
the way.
When the correct fluid level is

Engine Coolant
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.
The proper coolant for your Oldsmobile
will:
Give freezing protection down to-34”F
Give boiling protection up to 262°F
Protect against rust and corrosion.
Help keep the proper engine
Let the warning lights work as they
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
GM
Specification 1825-M with a complete
coolant flush and refill.
If you use this
mixture,
you don’t need to add anything

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.

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.
