I 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
Give boiling protection up to 258°F
Protect against rust and corrosion.

What to Use
Use a mixture of one-half clean water
(preferably distilled) and one-half
antifreeze that meets
“GM Specification
6038-M,” which won’t damage
aluminum parts. If you use this mixture,
you don’t need
to add anything else.
as
they should.
NOTICE:
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.
Some conditions, such as air trapped in
the cooling system, can affect the
coolant level in the radiator. Check the
coolant level when the engine is cold
and follow the steps under
Adding
Coolant for the proper way to add
coolant.
If you have to add coolant more than
four times a year, have your dealer
check your cooling system.
NOTICE:
If you use the proper coolant, you
don’t have to add extra inhibitors
or additives which claim to improve
the system. These can be harmful.
~~
Adding Coolant
To Check Coolant
When your engine is cold, the coolant
level should be at
ADD, 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.
I Radiator Pressure Cap
NOTICE:
Your radiator cap is a 15 psi
(105 1tPa) 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.
I 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 HOT mark.
When the engine compartment is
cool, the level should be at the
FULL
COLD mark.
