What does a 82 300D Turbo usually run at temprature. (AC running full blast, 90 degrees, and going down the interstate.) Mine runs at about 100 degrees. It usually dosent go over or below it after 30 minutes on the road, but I have seen the gauge go all the way up to red, and when I tried to open the hood the grille and hood release felt very hot to the touch along with the engine compartment. Any problems with this?
