So now it's in the 90's here in sunny PA, I've noticed that my engine fan seems to be permanently on, even when I first start up if it's later on in the day and the outside temp has gone up. Also, the temp gauge is showing 4 bars instead of the 3 it showed when the outside was in the 80's and the fan only went on when I got enthusiastic. Never had a car before where the fan was always on, even in hot weather. Normal? Dealer?
