the radiator pressure cap-even a
little-they can come out at high
speed. Never
turn the cap when
the cooling system, including the
radiator pressure cap, is hot Wait
for the cooling system and radiator
pressure cap to cool if you ever
have to turn the pressure cap.
~ I Vow to Add Coolant to the Radiator:
I. You can remove the radiator pressure
cap when the cooling system, including
the radiator pressure cap and upper radiator hose, is no longer hot.
Turn
the pressure cap slowly to the left
until it first stops. (Don’t press down
while turning the pressure cap.)
If you hear a hiss, wait for that to stop.
A hiss means there is still some pressure
left.
2. Then keep turning the pressure cap,
but now push down as you turn it.
Remove the pressure cap.

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 the
Index under
Engine Overheating.
The proper coolant for your Oldsmobile

should.
What to Use:
Use a mixture of one-half clean water
(preferably distilled) and one-half
antifreeze that meets “GM Specification
1825M,” which won’t damage aluminum
parts. You can also use a recycled
coolant conforming to GM Specification 1825M with a complete coolant flush
and refdl. Use

NOTICE
If you use an improper coolant

and be badly damaged. The repail
cost wouldn’t

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 mJLL HOT, or a
little higher.

Used Replacement Wheels Tire Chains
Using the wrong replacement
b wheels, wheel bolts, or wheel
nuts on your vehicle can be
dangerous. It could affect the
braking and handling
of your
vehicle, make your tires lose air
and make you lose control. You
could have a collision in which you
)r others could be injured. Always
lse the correct wheel, wheel bolts,
1 and wheel nuts for replacement.
IL
The wrong wheel can also cause
problems with bearing life, brake cooling, speedometer/odometer
calibration, headlight aim, bumper
height,
vehicle ground clearance,
adtire
or tire chain clearance to
.the-body
.~ and chassis,;f,;,ir, ~ ~~~ .. .~. ..~ = ~ ~=.=.=~~~~ ... ~~
Putting a used wheel on your
vehicle is dangerous. You
can t
know how it’s been used or
how many miles it’s been driven. It
-ould fail suddenly and cause an
,ccident. If
you have to replace a
wheel, use
a new GM original
equipment wheel.
e
Use tire chains only when y
must. Use only SAE Class ‘23’’
type chains that are the proper size
for your tires. Install them on the
front tires and tighten them as
tightly as possible with the ends
securely fastened. Drive slowly
and follow the chain manu-
facturer’s instructions. If
you can
hear the chains contacting your
vehicle, stop and retighten them.
If
the contact continues, slow down
until it stops. Driving too fast with chains on will damage your
vehicle.

Engine Accessory Drive Belt Inspection-
Inspect the drive belt for cracks, hying, wear and
proper tension. Replace as needed.
Cooling
System Service*-Drain, flush and refill
the system with new or approved recycled coolant
conforming to
GM Specification 1825M. Keep
coolant at the proper mixture as specified. See the
Index under Coolant. This provides proper freeze
protection, corrosion inhibitor level and 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 the pressure cap and
neck.
To help ensure proper operation, we recornmend a
pressure test of both the cooling system
and the
pressure cap.
Transaxle Service-Change both the fluid and
