I just got done reading thru my shop manual, and it doesn't mention whether the cooling fans are supposed to run after shutdown. Are they? The dang thing just overheated yesterday after cruising on the highway w/the ac on. Temp gauge read normal but shortly after it was shut off it dripped and steamed. The fans do come on with the ac on. Recent water pump. Still enough coolant in it after the overheat. Does anyone use water wetter? thanks.
