I’ve had my Escort Cosworth for 7 years now, and for all this time when the car gets to operating temperature, the temperature gauge has always shown between the black block and the “M”. In other words towards the bottom of the gauge. A few days ago, the temperature gauge has now started showing between the “O” and “R” of NORM all the time, even when stationery in traffic. I’ve checked the water level, and this hasn’t moved at all.

So the question is; where does your temperature gauge needle sit when running at operating temperature?
