It's connected to the coolant header tank, on the outlet of the engine.

For normal operation, a 95C switch might (?)  trigger too late in this rear sensor fitting, but you can get switches that work at different temps.   

I was thinking of the thermal switch from Davies Craig. It is supposed to be adjustable, so I figured 95C would be a conservative figure. If I wasn't planning on returning the original pump for warranty inspection and ordering a new one, I'd just find a switch locally, however since it will be shipped in the same box....   Actually my folks are going to Oz for a vacation on Nov1 and are planning on spending a week in Sydney visiting friends, so I think I will just give my Dad the old pump and he can hand deliver it to Leon and bring me back a new one. Now as long as Dad doesn't get lost ????
