My 300tdi is having a bit of an issue with the temp gauge...when i start the truck the gauge goes to half way then as the engine heats up it goes up past the half way then above red and stays there. The engine doesn't get hot or overheat in any way.
I fitted a new coolant temp sensor today (single wire one that goes on the 'stat housing)
Has anyone had any issues like this before?? Or any idea what it could be?? as im a bit confused on this one
