Which sensor - is there a sensor?

[Huw Powell]

The sensor is on the back, at the bottom.

Isn't there also a function where the AC can run the fan too, that could 
go wrong?

Anyway, find that radiator sender and unplug it, see if it fixes things, 
if it does, get a new one.  With sufficient deftness it can be replaced 
with very little coolant loss.

As far as the t-stat, wait til you fix the fan to worry about it - even 
a "closed" one passes some fluid, which might be enough in combo with 
the running fan to prevent full warm-up.

For now, I just disconnected the 3-wire plug on the fan, temperatures are falling way below freezing the next couple of days so there is no danger of overheating.
