Low Coolant Sensor

I recently had my Coolant flushed on my 2000 Grand Prix GTP and now the low coolant sensor light will not go off. I have had it back to the shop about 3 times and they don't know how to reset it. Does anyone know how to reset the low coolant sensor light.

Sounds as if the sensor is pluged or dirty....it is located on the left side of the radiator about half way down.You will need to drain out enough coolant to be able to remove the sensor.It is held in place by a clip that you slide off, then pull it out.

Thanks for the info.. The odd thing is that when I am sitting still for a few minutes and the temp goes up, the light goes off until it cools down again.

It could be a bad sensor and you can pick them up from most auto parts store's .Here is another thread about it.

My low coolant light was on for a year and when it got really hot it would go off and on. Took it out and scrubbed it with some 400g sandpaper and that fixed it.
