Ok, I took the rad cap off, put heater on full, hot and screen and just left it ticking over with the occasional throttle blip.
When it was first started there where bubbles/air in the header tank, after about 5 mins this settled down and the only time i got bubbles was if i blipped the throttle. Sat like this for about 20 mins until eventually the level rose and started pushing water out of the top of the header tank when I then switched off.
Temp gauge read normal (just under half way)
Fans didn't cut in at all - even after 20/25 mins. I saw them working about 4 weeks ago but maybe it didn't get hot enough this time to activate them?.
Top rad hose very hot, bottom stone cold. (just checked again and its warm?)
