1994 OLDSMOBILE SILHOUETTE engine coolant

Service &Appearance Cure
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.

The proper fluids and lubricants to use
are listed in Section D. Make sure
whoever services your vehicle uses
these. All parts should be replaced and
all necessary repairs done before you or
anyone else drives the vehicle.
ITEM
NO. SERVICE
1. Engine Oil and Filter Change* -
Always use SH or SG Energy
Conserving
I1 oils of proper viscosity.
The
“SH” or “SG” designation may
be shown alone
or in combination
with others, such as “SH/CD,”
“SH,
SG, CD,” “SG/CD,” etc. To
determine the preferred viscosity for
your vehicle’s engine (e.g.,
SAE 5W-
30 or SAE 10W-30), see
Engine Oil
in the Index.
2. Chassis Lubrication - Lubricate
suspension and steering linkage.
Lubricate the transaxle shift linkage,
and parking brake cable guides,
underbody contact points and
linkage.
3. Tire and Wheel Rotation and
Inspection
- For proper wear and
maximum tire life, rotate your tires
following the instructions in this
manual. See
Tires, Inspection E.
Rotation in the Index. Check the
tires for uneven wear
or damage. If
you see irregular or premature wear,
check the wheel alignment. Check for
damaged wheels also.
Engine Accessory Drive Inspection
- Inspect the drive belt for cracks,
fraying, wear and proper tension.
Replace as needed.
I
Cooling System Servicee - Drain,
flush and refill the system with new
or approved recycled coolant
conforming to GM Specification
I
1825M. Keep coolant at the proper 1
mixture as specified. See Coolant in
the
Index. This provides proper
freeze and boil protection, corrosion
I
inhibitor level and maintains proper ’
engine operating temperature.
Inspect hoses
and replace if they are
cracked, swollen or deteriorated.
Tighten screw-type hose clamps.
Clean the outside of the radiator and
air conditioning condenser. Wash tht
pressure cap and neck.
To help ensure proper operation, we
recommend
a pressure test of both the
cooling system and the pressure cap.
