These two symptoms are directly related. It sounds like you are going to have a faulty Engine Coolant Temp (ECT) Sensor. This sensor is what controls both the fan operation and the dash gauge. Replacing the ECT should solve both problems.

Do I need to drain out the water before I take out the sensor

 

Expert:  Ron Z. replied 6 years ago.
No. But you should remove the radiator cap. You will get a "little" spillage when removing the sensor, but thats to be expected. You should loose more than a couple ounces, nothing major.
