REPLACEMENT ENGINE COOLANT TEMPERATURE SENSOR : Engine Coolant Temperature Sensor is a sensor that is screwed into the engine's block or cylinder head. Common symptoms of a bad ECT sensor are overheating, hard starting conditions, poor idle, black smoke coming from the engine, Check Engine Light ON and the electric fans do not work properly.
