I am thinking of getting one of the Wizard radiators with an electric fan for the TR3A. I see it comes with a bung for a temperature probe to turn the fan on. I was wondering at what temperature the fan should turn on? I do not want it running too often and I do not want it not running often enough.

depends where the temp boss is
mine is in the metal return from the bottom outlet pipe and is 88/79 c 190/174 f this suite the car well
the engine builder has the boss in the top of the rad and fitted a 92/87c 197/188f version but i think this shows a bit hot on the car temp gauge. this position is also the hottest and doesn't take into account the cooling effect of the rad.
i wanted to know it it was still over hot after the rad had played its part as there would be a difference in air flow between driving and queuing.
this is with a 4lb cap.
i use a 220w fan fitted to rad.

I installed the wizard with fan kit in my tr3 about 8 years ,20k miles ago.
No problems.An on/auto manual toggle hidden under my dash works well.
If I roll up to traffic I can turn it on rather than wait for the temp to rise.
I Think on was 185 and off was 175 but I just ordered their tr3 setup.
