TEMPERATURE GAUGE FLUCTUATES BETWEEN THE MIDDLE ...

Temperature gauge fluctuates between the middle and the red zone (doesn't actually make into the red zone, just below it). The radiator and radiator cap have been replaced. The thermostat and gasket, temp sensor (twice), fan switch (twice) and the water pump were also replaced. The heater core was flushed as well. The fans do turn on but only for about 10 seconds at a time (and only when the gauge gets near the red zone) and then turn off. The antifreeze is not boiling and the car does keep running. Could it be a bad gauge? What else could be causing the temperature gauge to read so high? Thanks.
Find a mechanic with a scanner that can view live data and look at the actual temperature being reported to the Engine Computer. That sending unit is different than the one for the gauge. The first thing is to determine what the actual temperature is. Most radiator fans are turned on at around 210 - 220 degrees.
