Re: 00 Grand Prix// Low Coolant Light
The coolant light is controlled by a level sensor located about 3 inches below the radiator filler neck on the right side (passenger) of the radiator. As long as there are no cooling system problems or air in the system it could be the cause and is a common problem. See pic below:

Re: 00 Grand Prix// Low Coolant Light
I agree with Bob. The little metal pin gets mucked up with sludge and will cause a low coolant light to trip. If it's not clogged with sludge, then the sensor is most likely bad if the coolant level checks out (in the radiator) like Bob suggested.
