Well i'm 90% sure it's electrical, the temperature goes up when the lights are on, goes down when they are off, and the needle wavers up and down!
When driving normally, like I was in 4th doing 45ish, no load on the engine as such, and the temp rose to 90, then I got to the roundabout and it dropped to just over 80, then soon after was at 90 again. I really do hope it's not HG, there's a fair bit of pressure in the top pipe but not crazy, will bleed the system again to eliminate airlocks.
