1997 OLDSMOBILE BRAVADA radiator cap

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. Engine Fan
/II CAUTION:
An electric fan under the hood can start up even
when the engine is not running and can injure
you. Keep hands, clothing and
tools away from
any underhood electric fan.
If the coolant inside the coolant recovery tank is boiling,
don’t
do anything else until it cools down.

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.
When the coolant
in the coolant recovery tank is at
ADD, 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.

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.

How to Add Coolant to the Radiator
1. You can remove the pressure cap when the cooling
system, including the pressure cap and upper radiator
hose, is
no longer hot. Turn the pressure cap slowly
counterclockwise
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.

3. Fill the radiator with the proper coolant mixture, up
to the base of the filler neck. 4. Then fill the coolant recovery tank to
5. Put the cap back on the coolant recovery tank, but
leave the pressure cap
off.

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.

Radiator Pressure Cap 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.
Power Steering Fluid
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.

Halogen bulbs have pressurized gas inside and
can burst if you drop or scratch the bulb. You
or
others could be injured. Be sure to read and
follow the instructions on the bulb package.
