Pontiac 2000 Grand Am Owner's Manual page 204

When the engine is cold, the coolant level should be at
or above FULL COLD. If it isn't, you may have a leak
in the radiator hoses, heater hoses, radiator, water pump
or somewhere else in the cooling system.
5-12
CAUTION:
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.
