; What to Use
I Refer to the Maintenance Schedule to determine what
’ kind of lubricant to use. See “Recommended Fluids and
i Lubricants” in the Index.
1 , I Engine Coolant
; The cooling system in your vehicle is filled with new
1 DEX-COOL” engine coolant. This coolant is designed
I to remain in your vehicle for 5 years or 150,000 miles
I (240 000 km), whichever occurs first, if you add only
~ DEX-COOL” extended life coolant.
I i The following explains your cooling system and how to
i
~
i
add coolant when it is low. If you have a problem with
engine overheating, see “Engine Overheating” in
the Index.
I
A 50/50 mixture of water and the proper coolant for
1 your Oldsmobile will:
’ 0 Give freezing protection down to -34°F (-37°C).
~ 0 Give boiling protection up to 265 “F (129°C). I
~ 0 Protect against rust and corrosion.
0 Help keep the proper engine temperature.
0 Let the warning lights and gages work as
they should.
NOTICE:
When adding coolant, it is important that you use
only
DEX-COOL TM (silicate-free) coolant.
If silicated coolant is added to the system,
premature engine, heater core or radiator
corrosion may result. In addition, the engine
coolant will require change sooner
-- at
30,000 miles (50 000 km) or 24 months,
whichever occurs first.
What to Use
Use a mixture of one-half clean water (preferably
distilled) and one-half DEX-COOL
TM coolant which
won’t damage aluminum parts. Use GM Engine Coolant
Supplement (sealer) (GM Part
No. 3634621) with any
complete coolant change.
If you use this mixture, you
don’t need to add anything else.

1 NOTICE:
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
50150 mix of clean
water and
DEX-COOL TM coolant.
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.
If you have to add coolant more than four times a year,
have your retailer 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.

Checking 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.
Adding Coolant
If you need more coolant, add the proper coolant
mixture at the coolant recovery tank.
A CAUTION:
-
Turning the radiator pressure cap when the
engine and radiator are hot can allow steam and
scalding liquids to blow out and burn you badly.
With the coolant recovery tank, you will almost
never have to add coolant
at the radiator. Never
turn the radiator pressure cap
-- even a
little -- when the engine and radiator are hot.
Add coolant mixture at the recovery tank, but be careful
not to spill it.
' ,A CAUTION:
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.

Radiator Pressure Cap 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.
Power Steering Fluid
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.
