Temp gauge fluctuates and fans wont come on!

I recently was and still am experiencing a similar problem. It turned out to be a stuck thermostat and then when we replaced that part it got so hot that the sensor fried and the gauge was misreading info. i replaced the sensor but my gauge is still reading hot. So just check your sensors make sure your working off the right info.

/\ obd2 data also gives you actual temp (in numbers) to compare the oem gauge.
