Chevrolet 2003 Cavalier Owner's Manual page 245

The coolant level should
be at the FULL COLD
mark. If it isn't, you may
have a leak at the pressure
cap or in the radiator
hoses, heater hoses,
radiator, water pump or
somewhere in the
cooling system.
Heater and rac.,tor hoses, and other eng,,,e
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 fan is running.
If the engine is overheating, the fan should be running.
If it isn't, your vehicle needs service.
Notice: Engine damage from running your engine
without coolant isn't covered by your warranty.
Notice: When adding coolant,
it
is important that
you use only DEX-COOL@ (siiicate-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.
