Engine Overheating
’ You will find a coolant temperature gage on your
vehicle’s instrument panel. See “Gages” in the Index.
If Steam Is Coming From Your Engine
Steam from an overheated engine can burn you
badly, even if you just open the hood. Stay away
from the engine
if you see or hear steam coming
from it. Just turn it off and get everyone away
from the vehicle until it cools down. Wait until
there is no sign
of steam or coolant before you
open the hood.
If you keep driving when your engine is
overheated, the liquids in it can catch
fire. You or
others could be badly burned. Stop your engine if
it overheats, and get out of the vehicle until the
engine is cool.
NOTICE:
If your engine catches fire because you keep
driving with
no coolant, your vehicle can be
badly damaged. The costly repairs would not be
covered by your warranty.

; 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.

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.

6. Put the blade assembly pivot in the wiper arm hook.
Pull
up until the pivot locking tab locks in the
hook slot.
7. Carefully lower the wiper arm and blade assembly
onto the windshield.
Backglass Wiper Blade Replacement
See “Windshield Wiper Blade Replacement” in this
section for instructions on how to change the backglass
wiper blade. The backglass wiper blade will not lock
in
a vertical position like the windshield wiper blade, so
care should be used when pulling it away from
the vehicle.
Tires
Your new Oldsmobile comes with high-quality tires
made by
a leading tire manufacturer. If you ever have
questions about your tire warranty and where to obtain
service, see your Oldsmobile Wmanty booklet
for details. Poorly maintained and improperly used tires
are dangerous.

Overloading your tires can cause
overheating as a result
of too much friction.
You could have an air-out and
a serious
accident. See “Loading Your Vehicle” in
the Index.
Underinflated tires pose the same danger as
overloaded tires. The resulting accident
could cause serious injury. Check all tires
frequently to maintain the recommended
pressure. Tire pressure should be checked
when your tires are cold.
Overinflated tires are more likely to be
cut, punctured or broken
by a sudden
impact
-- such as when you hit a pothole.
Keep tires at the recommended pressure.
Worn, old tires can cause accidents.
If your
tread is badly worn, or if your tires have
been damaged, replace them.
