You will need to have cooling sys. pressure tested to find the leak. Most common is a hose clamp or hose , water pump or upper intake manifold seals and gasket. HTH

DON'T RUN IT ANY MORE UNTIL YOU CHECK IT! Those engines are notorious for leaking antifreeze into the crankcase which will seriously trash the engine. I had it happen twice with a 98 Bonneville which uses the same 3.8 liter six. Look for traces of coolant on the dipstick. If you suspect a leak, have the car towed in; don't drive it. Good luck!
