Buick REGAL 1997 Manual page 254

The coolant level should be at or above the COLD mark
on the overflow hose in the coolant bottle.
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.
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.
Engine damage from running your engine
without coolant isn't covered by your warranty.
If there seems to be no leak, with the engine on, check to
see if the electric engine fans are running. If the engine
is overheating, both fans should be running. If they
aren't, your vehicle needs service.
