2003 OLDSMOBILE SILHOUETTE heater

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
Recovery Tank
If you haven’t found a problem yet, but the coolant
level isn’t at
or above the FULL COLD mark, add a
50/50 mixture of clean, drinkable waterand DEX-COOL@
engine coolant at the coolant recovery tank. See Engine
Coolant on page
5-23 for more information.
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. With plain water or the
wrong mixture, your engine could get too hot
but you wouldn’t get the overheat warning.
Vn~lr en~ine mt1ld catch fire and YOU or others
could be burned. Use a 50/50 mixture of clean,
drinkable water and DEX
COOL@ coolant.
5-31

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.
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 or
above the
FULL COLD mark, start your vehicle.
If the overheat warning continues, there’s one more
thing you can try.
You can add the proper coolant
mixture directly to the radiator, but be sure the cooling
system
is cool before you do it.
