CAUTION
Don’t keep driving if the oil I
pressure is low. If you do,
your engine can become
so hot that
it catches fire. You or others could
be burned. Check your oil as soon
as possible and have your vehicle
serviced.
Oil Pressure indicator
(ANALOG CLUSTER)
This indicator tells you if there could be
a problem with your engine
oil pressure.
The pointer should be above the red
zone when the engine is running.
Readings in the red area tell
you that
the engine is low on oil, or that
you
might have some other oil problem. See
the
Index under Engine Oil.

Your Driving and the Road
Driving a Long Distance
Although most long trips today are
made on freeways, there are still many
made on regular highways.
Long-distance driving on freeways and
regular highways is the same
in some
ways. The trip has to be planned and
the vehicle prepared, you drive at
higher-than-city speeds, and there
are
longer turns behind the wheel. You’ll
enjoy your trip more if you and your
vehicle are in good shape. Here are
some tips for a successful long trip.
Before Leaving on a Long Trip
Make sure you’re ready. Try to be well
rested. If you must start when you’re
not fresh-such as after a day’s work
don’t plan to make too many miles that
first part of the journey. Wear
comfortable clothing and shoes you can
easily drive in.
Is your vehicle ready for a long trip? If
you keep it serviced and maintained, it’s
ready to go. If it needs service, have it
done before starting out. Of course,
you’ll find experienced and able service
experts in Oldsmobile dealerships all
across North America. They’ll be ready
and willing to help if you need it. Here are
some things you can check
before a trip:
Windshield Washer Fluid: Is the
reservoir
full? Are all windows clean
inside and outside?
shape? Have you checked
all levels?
the lenses clean?
safe, trouble-free trip. Is the tread
good enough for long-distance
driving?
Are the tires all inflated to
the recommended pressure?
Weather Forecasts: What’s the
weather outlook along your route?
Should you delay your trip a short
time to avoid a major storm system?
Maps: Do you have up-to-date maps?
Wiper Blades: Are they in good

Cooling System
When you decide it’s safe to lift the
hood, here’s what you’ll see:
(A) Coolant recovery tank
(B) Radiator pressure cap
(C) Electric engine fan
If the coolant inside the coolant
recovery tank is boiling, don’t do
anything else until it cools down. The
coolant level should be at or above
the
COLD mark.
If it isn’t,
you may have a leak in the
radiator hoses, heater hoses, radiator,
water pump or somewhere else in the
cooling system.
I
- 1
CAUTION I
Heater and radiator hoses,
and other engine parts, can
1;, ;cry hot. Don’t touch them. If
you do,
you can be burned.
Don’t run the engine
if there is a
leak. If you
run the engine, it could
lose all coolant. That could cause
an engine fire, and you could be
burned. Get any leak fixed before
I
you drive the vehicle.
I
If there seems to be no leak, check to
see
if the electric engine fan is running.
If the engine is overheating, the fan
should be running.
If it isn’t, your
vehicle needs service.
How to Add Coolant to the Coolant
Recovery
Tank:
If you haven’t found a problem yet, but
the coolant level isn’t at or above
COLD, add a
50/50 mixture of clean
water (preferably distilled) and a proper
antifreeze at the coolant recovery
tank.
(See the Index under Engine Coolant
for more information abaut the proper
coolant
mix.)

Problems on the Road
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
50/50 mix of clean
water and a proper antifreeze.

You can be burned if you
spill coolant on hot engine
-I.& Coolant contains ethylene
pdrts are hot enough. Don't spill
ycol
and it will burn if the engine

When the coolant
in the coolant
recovery tank is at or above
COLD,
start your vehicle.
If the overheat
warning continues,
there's one more
thing you can try. You
can add the proper coolant mix directly
to the radiator, but be sure the cooling
system
is cool before you do it.

can blow out and burn you badly.
They are under pressure, and
if you
turn 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.

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

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 recommend a
pressure test of both the cooling system and the
