It does seem low doesn't it. The "normal" running temperature of the Duratec is, I believe, 92°. Once hot mine is always between 90° and 100°. I think that the fan goes to the faster speed at about 95° and clicks off when the temperature drops below 92° but this is just from memory, I would have to check that.
Peter, there could be a difference between coolant inlet temperature and the point where the coolant sensor is mounted at your engine, there placed probably reading higher temperatures.
