I'm running a 2011 NA Evora which has an odd thing going on with the coolant temperatures which I don't know if it's at all normal. Trundling along at town speeds temperatures warm up to normal (halfway or slightly lower on the gauge) as I'd expect. If I then have a short spirited drive on the country roads for 5 miles or so, using more of the rev range, the temperature vanishes back down the scale. Usually down to a few pixels above the bottom, but on a cold night two days ago temperatures dropped right off the bottom of the scale which was more worrying! Going back in to town driving the temperature slowly comes back up. The little sustained motorway driving I do the temperature sits around 1/3 up the scale.
Last time I was out for an extended drive (back end of the summer) I don't recall anything unusual in temperatures later in the journey. To my non mechanical mind it's like there's a reservoir of cold coolant somewhere in the system that's being flushed past the temperature sensor once coolant starts circulating when the revs rise. So I don't know if this is normal and a symptom of the short journeys/initial warm up period or something to worry about and indicating a blockage?
