engine Oldsmobile Cutlass Supreme 1994 s Owner's Guide

Find the positive (+) and negative
(-) terminals on each battery. Your
Oldsmobile has a remote positive
(+)
jump starting terminal. The terminal
is on the same side
of the engine
compartment as your battery.
You should always use the remote
positive
(+) terminal instead of the
positive
(+) terminal on your battery.
To uncover the remote positive
(+)
terminal, lift the red plastic cap.
5. Check that the jumper cables don’t
have loose or missing insulation.
If
they do, you could get a shock. The
vehicles could be damaged, too. Before
you connect
the cables, here
are some basic things
you should
know. Positive
(+) will go to positive
(+) and negative (-) will go to
negative
(-) or a metal engine part.
Don’t connect
(+) to (-) or you’ll get
a short that would damage the
battery and maybe other parts, too.

6. Connect the red positive (+) cable to
the positive
(+) terminal of the
vehicle with the dead battery. Use a
remote positive
(+) terminal if the
vehicle has one.
7. Don’t let the other end touch metal.
Connect it to the positive
(+)
terminal of the good battery. Use a
remote. positive (+) terminal if the
vehicle has one.
8. Now connect the black negative (-)
cable to the good battery’s negative
(-) terminal. Don’t let the other end
touch anything until the next step.
The other end
of the negative cable
doesn’t go to the dead battery. It goes
to a heavy unpainted metal part on
the engine
of the vehicle with the
dead battery.
9. Attach the cable at least 18 inches
(45 em) away from the dead battery,
but not near engine parts that move.
The electrical connection is just as
good there, but the chance of sparks
getting back to the battery is much
less.
10. Now start the vehicle with the good
battery and run the engine for a
while.
11. Try to start the vehicle with the
dead battery.
If it won’t start after a
few tries, it probably needs service.

Cooling System
When you decide it’s safe to lift the
hood, here’s what you’ll see:
(A) Coolant recovery tank
(€3) Radiator pressure cap
(C) Electric engine fans 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.

NOTICE:
In cold weather, water can freeze
and crack the engine, radiator,
heater core and other-parts. Use the
recommended coolant.

2. Then keep turning the pressure cap,
but now push down as you turn it.
Remove the pressure cap. 3. After the engine cools, open the
coolant air bleed valve or valves.
3100 V6 (VIN Code M): There are
two bleed valves. One is located on
the thermostat housing. The other is
located on the thermostat bypass
tube.
3.4L V6 (VIN Code X): There are
two bleed valves. They are located
on
the thermostat housing and heater
inlet pipe.

4. Fill the radiatot with the praper mix,
.up to the base of the filler neck. If
you see a stream af coolant coming
from. an air bleed valve, close the
valve. Otherwise.,
close. the valves
&er the radiator is filled.
5. Rinse or wip*e any spilled coolant
from the engine compartment,
6. Then fill the coolant recovery tank to
the
COLD mark.
7. Put the cap back on the coolant
recovery tank, but. leave the radiator
pressure cap
off.

8. Start the engine and let it run until
you can feel the upper radiator hose
getting hot. Watch out for the engine
fans.
9. By this time the coolant level inside
the radiator filler neck may be lower.
If the level is lower, add more of the
proper mix through the filler neck
until the level reaches the base of the
filler neck.
10. Then replace the pressure cap. At
any time during this procedure if
coolant begins to flow out of the
filler neck, reinstall the pressure
cap. Be sure the arrows on the
pressure cap.line up like this.
11. Check the coolant in the recovery
tank. The level in the coolant
recovery tanlc should be at the
HOT
mark when the engine is hot or at
the
COLD mark when the engine is
cold.
Ifa Tire Goes Flat
It’s unusual for a tire to “blow out”
while you’re driving, especially
if you
maintain your tires properly. If air goes
out of a tire, it’s much more likely to
leak out slowly. But if you should ever
have
a “blowout,” here are a few tips
about what to expect and what to
do:
If a front tire fails, the flat tire will
create a drag that pulls the vehicle
toward that side. Take your foot off the
accelerator pedal and grip the steering
wheel firmly. Steer to maintain lane
position, then gently brake to a stop
well out of the traffic lane.
A rear blowout, particularly on a curve,
acts much like a slid and may require
the same correction you’d use
in a skid.
In any rear blowout, remove your foot
from the accelerator pedal. Get the
vehicle under control by steering the
way you want the vehicle to go. It may
be very bumpy and noisy, but you can
still steer. Gently brake to a stop, well
off the road if possible.
If a tire goes flat, the next section shows
how to use your jacking equipment to
change a flat tire safely.

Fuel
Be sure the posted.octane is at least 87.
I€ the octane is less than 87, you may
get a heavy knocking noise when you
drive. If it's bad enough, it .can damage
your engine.

Gasolines for Cleaner Air
Your use of gasoline with deposit
control additives will help prevent
deposits from forming
in your engine
and fuel system. That helps keep your
engine in tune and your emission
control system working properly. It’s
good for your vehicle, and you’ll be
doing your part for cleaner air.
Many gasolines are now blended with
oxygenates. General Motors
recommends that you use gasolines
with these blending materials, such as
MTBE and ethanol. By doing so, you
can he€p clean the air, especially in
those parts
of the country that have
high carbon monoxide levels.
In addition, some gasoline suppliers are
now producing reformulated gasolines.
These gasolines are specially designed
to reduce vehicle emissions. General
Motors recommends that you use
reformulated gasoline. By-doing
so, you
can help clean the air, especially in
those parts of the country that have
high ozone levels.
You should ask your service station
operators if their gasolines contain deposit control
additives and
oxygenates, and if they have been
reformulated to reduce vehicle
emissions.
