heater OLDSMOBILE BRAVADA 1998 User Guide

U
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.
1 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 engine cooling 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 clecrn
\,L*crtet- (preferably distilled) and DEX-COOL@ engine
coolant
at the coolant recovery tank. (See “Engine
Coolant”
in the Index for more information.)
I A CAUTION:
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 mixture will. Your vehicle’s coolant
warning system
is set for the proper coolant
mixture. With plain water or the wrong mixture,
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 mixture of clean water and
DEX-COOL@ coolant.

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 mixture.
I
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 the
ADD mark. start your vehicle.
If the overheat warning continues, there's one more
thing you can try.
You can add the proper coolant
mixture dire.ctly to the radiator, but
be sure the cooling
system
is cool before you do it.

NOTICE:
When adding coolant, it is important that you use
only
DEX-COOL@ (silicate-free) coolant.
If coolant other than DEX-COOL
is added to the
system, premature engine, heater core or radiator corrosion may result. In addition, the
engine coolant will require change sooner
-- at
30,000 miles (50 000 km) or 24 months,
whichever occurs first. Damage caused by the use
of coolant other than DEX-COOL@
is not
covered by your new vehicle warranty.
What to Use
Use a mixture of one-half OIPLUZ rt:afer (preferably
distilled) and one-half
DEX-COOL@ coolant which
won't damage aluminum parts.
If you use this mixture,
you don't need to add anything else.
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 mixture will. Your vehicle's coolant
warning system is set for the proper coolant
mixture. With plain water or the wrong mixture,
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 mixture of' clean water and
DEX-COOL@ coolant.

NOTICE:
If you use an improper coolant mixture, your
engine could overheat and be badly damaged.
The repair cost wouldn’t be covered by your
warranty.
Too much water in the mixture can
freeze and crack the engine, radiator, heater core
and other parts.
If you have to add coolant more than four times a year,
have your retailer check your cooling system.
I NOTICE: I
If you use the proper coolant, you don’t have to
add extra inhibitors or additives which claim to
improve the system. These can be harmful.
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.
