Guys

Ive taken the 3 door on its maiden voyage today, but after a little driving the temp gauge was well over the half way mark but below the red, i popped the heater on and and the temp dropped after a while and just remained just slightly over half way with the heater on.

I got home and checked the fans and they didnt/dont come on at all even when the temp is quiet high.

I pulled the plug off the red? sensor/stat screwed into the bottom of the rad and linked the plug out, and now the fans run continously,

So my question is;

Is it the red? sensor/stat in the bottom of the rad?

Thanks in advance.
