Hi going back a few months ago my 1.8tdci (2007) focus temp gauge would always stay at 60 degress on my trip to and from work from a cold start (i work 1.8 miles away). Then just before alternator went on the car the gauage would rise no more than 75 degrees. Since getting the alternator changed i find that within the short journey the temp gauge will go mainly between 60 and 75 (usually half way). When its warm warm it stays just below half way never goes past but on cold start will go up and down a bit (i.e. waiting at lights). I am not loosing oil, coolant etc so just wondering if its normal or maybe a dodgy sensor.

It takes around 5 mins before get home due to lights traffic roundabouts etc. It will only start moving when near home or just parked up. Think i may get a new sensor put in.

I've got the 1.8tdci and you temp gauge needs more than 5 mins to get going, as stated above, they take a while to get warm. And I've not seen mine go past half way in the year I've owned it lol.
