my temp gauge went crazy after my coilpack conversion, so I thought the signal wire has an earth somewhere. I replaced the wire and connected the sensor directly to the Temp gauge, only to find out that it was in fact the sensor which was buggered. After replacing the sensor (a big thank you to Stu@MSD), the water temp seemed a bit high, and it was traced down to a non working fan. Replaced the fan switch, but the damn thing doesn't come on until the temp has passed the N. So the temp fluctuates between the red line and N at the moment. This doesn't seem right. Should I use the original harness for signal (maybe difference resistance in the wire?) or is my themostat not working?

How come the escos themostats cost so much more than the 2wd? How do I bleed the cooling system? I have a swirl pot, do I still need to bleed it for air?

Thanks for all the help
