It is on the top of the engine right above the thermostat. If you look where your upper hose fastens to engine it is the thing on the aluminum cover that has wires going to it. I have replaced mine but it still fluxuates back and forth. The water pump is probably your best bet if it keeps acting up. It is easy to change the sensor but do not overtighten. The cover is aluminum and will strip out easily.

If it is a temperature sensor, it is usually located on the top of the engine near the thermostat. If it is a "low coolant sensor", then it is located in the radiator (it will be the only item in the radiator that has a electric wire going to it) Either way, you would drain the coolant enough to be below the sensor, and then remove it and replace it with a new one. They are usually under $10-$20

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

Where is the coolant sensor on a 2001 Mercury Sable and is it possible to replace it without replacing the entire coolant reservoir?

NOTE: this answer is describing the location of the engine coolant temperature sensor - NOT the coolant sensor in the reservoir that warns when the level gets too low.The coolant temperature sensor is located directly adjacent to the thermostat housing. The thermostat housing is what the upper radiator hose (toward the right side of the engine compartment) connects to. You do not have to replace the reservoir to replace this part, but leaky coolant reservoirs are a common problem on this model.
