I was doing some troubleshooting its leaking. I just had thermostat change. What i do seem to notice that my fan will come on when it gets to that half way mark and then the temp drops down.
Can you define fluctuates please. It used to be a common complaint on these that the temp gauge would go down when accelerating and come up on the over-run. That is normal due to a two stage calibration close band cold wide band hot with the PCM and IPC software.
