I kinda wonder if its the alternator, but the car runs fine. I just want to replace it though to be on the safe side.
My first thought would be, did you check the coolant? If you are low on coolant due to a leak, or just a lack of a full fill from the last time, then that would be causing your temp issues. I would advise completely flushing, filling, and burping the coolant and see if that helps.
You may not be running too hot now, but it is still in the winter months and once summer comes you may have some more serious temps to deal with.
Also, if the dealer told you that the engine is running +400F from normal operating temperature...I might think about going to another dealer, because honestly. That isn't possible without making the engine go all sorts of not right.
