If you sure it's got enough coolant probably a faulty sensor. Un plug the sensor. (Most are on bottom of resivior) if light then goes out replace sensor.

http://www.sparkys-answers.com/2010/02/2002-pontiac-grand-prix- changing-low.html -- check this out. Yours is on passenger side of radiator couple inches down from the filler cap.

Sometimes these sensors will get dirty and the light will stay on. Also, if they replaced the radiator, the hole where the sensor attaches to the radiator must be drilled out. Otherwise the sensor will be dry and the light will stay on. HTH. -Jim

If the shop cannot figure it out, you should go somewhere else because they are not any good, or change the sensor yourself.

These sensors can be a little tricky. I checked the factory shop manual for my '00 Grand Prix. It talks about how the low coolant light may stay on for two to three days after replacement or cooling system service. This is normal and the customer should be advised accordingly. HTH. -Jim
