Sounds like you have a thermostat problem. Have it changed and have the cooling system flushed and refilled with fresh coolant. That should cure the problem.

Even a new coolant temperature sensor may be damaged by over temperature. Thermistors also drift off calibration with age. Check for corrosion on the connector.

Check your oil and see if coolant has leaked into the engine...A known problem with 3.8L engines are defective intake manifold gaskets that allow coolant into the engine block. Costly repair.

Why would the low coolant light come on in a 1999 cavalier if it is not low?
The sensor is located underneath the coolant recovery tank. On a 1999 Cavalier, there could be some sludge built up underneath the tank. Unfortunately the sensor alone cannot be replaced, the entire tank and sensor comes as one piece and must be replaced. tap on the side of your fill/overflow tank where the sensor is located sometimes they get stuck
