Coolant light wont shut off after adding cooland 1992 300te

Hello, If you are sure that the reservoir is filled properly, unplug the 2 pin connector on the side of the reservoir and see if the light goes out. If the light goes out, you need to replace the sensor which is what the connector hooks to.
