2003 OLDSMOBILE AURORA heater

If the coolant inside the coolant recovery tank is boiling,
don’t do anything else until it cools down. The vehicle
should be parked on a level surface.
A low coolant level should be indicated by a LOW
ENGINE COOLANT message on the Driver Information
Center.
If it is, you may have a leak at the pressure
cap or
in the radiator hoses, heater hoses, radiator,
water pump or somewhere else in the cooling system. 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.
If there seems to be no leak, with the engine on, check
to see
if the electric engine cooling fans are running.
If the engine is overheating, both fans should be
running.
If they aren’t, your vehicle needs service.
Notice: Engine damage from running your engine
without coolant isn’t covered by your warranty.
See “Overheated Engine Protection Operating
Mode’’ in the Index for information on driving to a
safe place
in an emergency.

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.
How to Add Coolant to the Coolant
Surge Tank
If you haven’t found a problem yet, check to see if
coolant is visible in the surge tank. If coolant is visible
but the coolant level isn’t at or above the
FULL COLD fill
mark line (4.5 inches (1 1 cm) from the top of the filler
neck), add a
50/50 mixture of clean, drinkable water and
DEX-COOL@ coolant at the coolant surge tank, but be
sure the cooling system, including the coolant surge tank
Coolant on page 5-24 for more information.
If no coolant is visible in the surge tank, add coolant as
follows:

Steam and scalding Ii ids from a hot cooling
system can blow out and burn you badly. They
are under pressure, and
if you turn the coolant
surge tank pressure cap -- even a little -- they
can come out at high speed. Never
turn the
cap when the cooling system, including the
coolant surge tank pressure cap, is hot. Wait
for the cooling system and coolant surge tank
pressure cap to cool if you ever have to turn
the pressure cap.

1 Adding only plain water to your cooling
system can be dangerous. Plain water, or
some other liquid such as alcohol, can boil before the proper coolant mixture will. Your
vehicle’s coolant warning system is set for the proper coolant mixture.
CAUTION: (Continued)
I I
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, drinkable 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
IT-:-’=- e.
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.
