1997 OLDSMOBILE BRAVADA coolant level

A reading in the low pressure zone may be caused by a
dangerously low oil level or other problems causing low
oil pressure.
Don’t keep driving if the oil 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 yo1
vehicle serviced.
NOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.

+# BLEND: Airtlow is divided equally between the
heater floor outlet and the windshield defroster outlets.
%? DEFROST This setting directs most air through
the windshield defroster outlets and some through the
heater outlets.
Air Conditioning
On hot days, open the windows long enough to let hot
inside air escape. This reduces the time
it takes for your
vehicle to cool down. Then keep your windows closed
for the air conditioner to work its best.
For quick cool-down on very hot days, use
MAX A/C
with the temperature knob turned counterclockwise.
This setting should be used to keep odors and/or dust
from entering the vehicle. For normal cooling on hot
days, use A/C with the temperature knob turned
counterclockwise.
On cool but sunny days, use BI-LEVEL A/C to deliver
warm air to the floor and cooler air to the instrument
panel outlets.
When the air conditioner is on,
you may sometimes
notice slight changes
in your vehicle‘s engine speed and
power. This is normal because the system is designed to
cycle the compressor on and off to keep the
desired temperature.
Heating
The heater works best if you keep your windows closed
while using
it. On cold days, use HEATER with the
temperature knob turned clockwise.
BLEND is useful in
cool weather when you have fog or ice on the
windshield or side windows.
If you use the optional engine coolant heater before
starting your engine, your heating system will produce
warmer
air faster to heat the passenger compartment in
cold weather. See “Engine Coolant Heater” in the Tndex.

Heater and radiator hoses, and other engine
parts, can be very 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 you drive the vehicle.
The coolant level should be at the ADD 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:
Engine damage from running your engine
without coolant isn’t covered by your warranty.
If there seems to be no leak, start the engine again. See
if the fan speed increases when idle speed is doubled by
pushing the accelerator pedal down.
If it doesn’t, your
vehicle needs service.
Turn off the engine.

How to Add Coolant to the Coolant
Recovery Tank
If you haven’t found a problem yet, but the coolant level
isn’t at the
ADD mark, add a 50/50 mixture of clean
water (preferably distilled) and DEX-COOL TM
(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 coolant.
I NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
Use the recommended coolant and the proper
coolant mix.

6. Start the engine and let it run until you can feel the
upper radiator hose getting
hot. Watch out for the
engine fan.
7. By this time, the coolant level inside the filler neck
may be lower. If the level is lower, add nm-e of the
proper coolant mixture through the filler neck ~~ntil
the level reaches the base of the filler neck.
8. 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.

Checking Coolant
When your engine is cold, the coolant level should be at
ADD, or a little higher. When your engine is warm, the
level should be up to
FULL HOT, or a little higher.
Adding Coolant
If you need more coolant, add the proper coolant
mixture at the coolant recovery tank.
A CAUTION:
-
Turning the radiator pressure cap when the
engine and radiator are hot can allow steam and
scalding liquids to blow out and burn you badly.
With the coolant recovery tank, you will almost
never have to add coolant
at the radiator. Never
turn the radiator pressure cap
-- even a
little -- when the engine and radiator are hot.
Add coolant mixture at the recovery tank, but be careful
not to spill it.
' ,A CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and it will burn if the engine parts are hot
enough. Don't spill coolant on
a hot engine.
