I already replace my coolant temp. Sensor. I notice that when I turn the ac on the fan is running. I also notice that when I am at park and have the ac on the temperature is starting to go up, but when I am driving the temperature is back to normal.

Well the fan is supposed to go on when you turn the a/c on. And the temp will always go up a little when idling. Untill you move and the air passes throught the radiator is when it will go down some, but over heating is when your temp gauge is well into the redzone.
