The coolant level sensor is known to fail in that the magnet attached to the sensor comes loose and falls to the bottom.
These are not repairable, and will require either black tape over the warning light with vigilant monitoring of the levels by you, or replace the tank.

Disconnect the Sensor approach...
The coolant sensor is located in the coolant reservoir bottle. It cannot be serviced, you can only replace the reservoir. However, if just the sensor is bad, you can also try unplugging the sensor at the coolant reservoir bottle. Unscrew the two screws holding the reservoir bottle in place. With the bottle loose, tilt the bottle slightly toward you until you see wiring coming out of the reservoir bottle, that will be the wiring for the sensor plug. Unplug the sensor plug, and reattach the reservoir bottle. The Low Coolant light will not come on anymore, but you will now need to keep tabs on the antifreeze fluid level in the reservoir by occasionally checking
the fluid level.

There is a coolant level sensor in the bottom of the coolant tank. If the tank has enough coolant, then the sensor is bad. You can buy a new tank for about $50 (Rockauto.com or Autozone) and replace it in an hour or so. Or just disconnect the cable from the sensor and check your coolant level on a regular basis.

where is the engine coolant temperature sensor- low input locationon a 1998 ford taurus
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.

The coolant sensor is on top of the engine. It is between the ignition coil and the tfi module.
It is in the passenger side coolant tank on the radiator. If the light is on and the coolant is at the proper level then the sensor is defective. To replace it you will have to drain the radiator. Disconnect the wire and remove the clip and remove the sensor.
The coolant temperature sensor can be found on the front of the engine, near the thermostat. Remove the coolant temperature sensor retaining nut, to replace it.
The coolant temperature sensor on an 89 Taurus with a 3.8L V-6 is located directly above the thermostat, where the upper radiator hose connects to the engine. the sensor is positioned vertically and has 2 wires coming off of it.
