The Coolent Sensor on my 2002 Chevy Impala can be located as follows:
Look at Radiator Cap. Now shine a Flash light down to the left of the Radiator cap just behind the battery. You will see the square sensor with two wires plugged into bottom. The sensor is square and has a wire connector that holds it in the radiator. Advance Auto Cost $58.00.
