I would suspect either faulty engine coolant temp. Sensor or bad water pump. Double check to make sure coolant level is full and not leaking anywhere (hoses, radiator etc.). If OK here, inspect the drive belt around the water pump. Make sure it is not damaged or loose. Also listen to the pump with a mechanics stethoscope to see if the bearings are making any noises. If you are certain the temp. Gauge is reading correctly then I would suggest replacing the water pump.
