It has gone as high as the red but now since I'm aware of the problem it will get to about 3/4 of the way to boilover. After I turn the heat on and get the car moving it will go back down to just below 1/2. I realize that i haven't hit the boilover point yet but I am ruuning F/I thus the engine is under much more strain than if N/A.
