Right over the past week or so my tempertaure gauge has been playing up, it never goes just above half way but would drop quite abit (about 3 notches).
Anyway Fred got me a coolant temp new sensor which i replaced, and the problem is still there. I've noticed if i go and give the car a bit of stick then the car sits at the correct temperature but the minute i start slowing it starts to drop.
I checked the hose coming of the thermostat today and it was warm but not boiling so to speak, this was after a 40 minute drive.
Also my mpg is also shocking at the minute, at 70mph i can just break 34mpg if i try, if not it's around 28.
Anybody got any ideas what the problem is please before i have to get it into Fred again, i'd like to try and solve it myself for a change lol.
Cheers.
