Age old question of coolent temp gauge

[duckman]

Hi guys!
You've heard it many times before I'm sure, but temp gauge moves down when driving, hot air comes though fine, and changed the temp sensor today and bled system,
So I'm guessing there's a chaft wire, it's there a ussual place where this happens?

i had the same problem, pretty sure the thermostat would sort it too

Na not yet, thought it would be more of a wiring issue so I didn't bother because the air does come out hot and stays hot, but I'll give the thermostat a go, cheers guys

Change your thermostat before you start looking at other things .
