1996 OLDSMOBILE SILHOUETTE overheating

A CAUTION:
Your regular brake system may not be working
properly if the anti-lock brake system warning light
is flashing. Driving with the anti-lock
brake system warning light flashing can lead to an accident. After you’ve pulled
off the road
and stopped carefully, have the vehicle towed
for service.
If the anti-lock brake system warning light stays on
longer than normal after you’ve started your engine, turn
the ignition off. Or, if the light comes on and stays on
when you’re driving, stop as soon as possible and turn
the ignition
off. Then start the engine again to reset the
system. If the light still stays on, or comes on again
while you’re driving, your Oldsmobile needs service. If
the light is on but not flashing and the regular brake
system warning light isn’t on, you still have brakes, but
you don’t have anti-lock brakes.
The anti-lock brake system warning light should come
on briefly when you turn the ignition key to
RUN. If the
light doesn’t come on then, have it fixed
so it will be
ready to warn you if there
is a problem.
Engine Coolant Temperature Gage
’ 260
This gage shows the engine coolant temperature. If the
gage pointer moves into the red area, your engine
is too
hot! It means that your engine coolant has overheated. If
you have been operating your vehicle under normal
driving conditions, you should pull
off the road, stop
your vehicle and turn
off the engine as soon as possible.
In “Problems on the Road,” this manual shows what to
do. See “Engine Overheating” in the Index.

Driving On Grades Parking on Hills
Reduce speed and shift to a lower gear before you start
down a long or steep downgrade. If you don’t shift
down, you might have
to use your brakes so much that
they would get hot and no longer work well.
On
a long uphill grade, shift down and reduce your
speed to around 45 mph
(70 km/h) to reduce the
possibility of engine and transaxle overheating.
If you are towing a trailer that weighs more than
1,000 lbs. (454 kg), and you have an automatic transaxle
with AUTOMATIC OVERDRIVE
(@), you may prefer
to drive in THIRD (D) instead of AUTOMATIC
OVERDRIVE
(@) (or, as you need to, a lower gear).
This will minimize heat build-up and extend the life
of
your transaxle.
You really should not park your vehicle, with a trailer
attached,
on a hill. If something goes wrong, your rig
could start to move. People can be injured, and both
your vehicle and the trailer can be damaged.
But
if you ever have to park your rig on a hill, here’s
how to do
it:
1. Apply your regular brakes, but don’t shift into
PARK (P) yet.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then apply your parking
brake, and then shift to PARK
(P).
5. Release the regular brakes.

axle inboard
of the spring.

You will find a coolant temperature gage on your
Oldsmobile’s instrument panel. See “Engine Coolant
Temperature Gage”
in the Index. You also have a low
coolant level light on your instrument panel. See “Low

A CAUTION:
Heater and radiator hoses, and other engine
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 you drive the vehicle.

NOTICE:
Engine damage from running your engine
without coolant isn’t covered by your warranty.
If there seems to be no leak, with the engine on, check to
see
if the electric engine fan(s) are running. If the engine
is overheating, both fan(s) should be running.
If they
aren’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 the FULL HOT mark, add a 501.50
mixture of den72 water (preferably distilled) and
DEX-COOL TM (orange-colored, silicate-free) antifreeze
at the coolant recovery tank. (See “Engine Coolant” in
the Index for more information.)
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
DEX-COOL TM antifreeze.

Refer to the Maintenance Schedule to determine what
kind
of transaxle fluid to use. See “Recommended
Fluids and Lubricants” in the Index.
If the fluid level is low, add only enough
of the proper
fluid to bring the level into the cross-hatched area on
the dipstick.
1. Pull out the dipstick.
2. Using a long-neck funnel, add enough fluid at the
dipstick hole to bring it
to the proper level. It doesn’t
take much fluid, generally less than a pint
(0.5 L).
Don ’t overfill. We recommend you use only fluid
labeled DEXRON@-111, because fluid with that
label is made especially for your automatic transaxle.
Damage caused
by fluid other than DEXRON-111 is
not covered by your new vehicle warranty.
0 After adding fluid, recheck the fluid level as
described under “How
to Check.”
When the correct fluid level is obtained, push the
dipstick back in all the way. The
cooling system in your vehicle is filled with new
DEX-COOL
TM (orange-colored, silicate-free) engine
coolant. This coolant is designed to remain in your
vehicle for
5 years or 100,000 miles (166 000 km),
whichever occurs first.
The following explains your cooling system and how to
add coolant when it is low.
If you have a problem with
engine overheating, see “Engine Overheating” in
the Index.
A 50/50 mixture of water and the proper coolant for
your Oldsmobile will:
0 Give freezing protection down to -34°F (-37°C).
0 Give boiling protection up to 265°F (129°C).
Protect against rust and corrosion.
0 Help keep the proper engine temperature.
0 Let the warning lights and gages work as they should.

Radiator Pressure Cap
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.
When you replace your radiator pressure cap, an AC@
cap is recommended.
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.
When
you replace your thermostat, an AC@ thermostat
is recommended.
Power Steering Fluid
The power steering fluid reservoir is located to the right
of the engine coolant reservoir, at the back of the
engine compartment.

Tires
We don’t make 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 Warranty
booklet for details.
/!1 CAUTION:
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.
CAUTION: (Continued)

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.
