[6pack] Electric fan thermostat and electrics ?

Stan,
I'd encourage going the relay route. My original 12" Hayden Fan included a
relay with the thermostat as did the new 16" Spal fan that I installed in
Sept. 

Seeing as you have your radiator out of the car, I assume you'll be getting
it cleaned,  flushed and tested by a radiator shop. Why not have them solder
in a bung at the top corner of the radiator to match whatever fan kit you
buy?

Hi and happy new year.

As part of my conversion to Webers I will no longer be using the water
circuit through that carbs and this will free up that port on the water pump
housing.
I could block it with a brass plug or I could screw in another water temp
sender unit and have it there as a spare but I was also wondering if I could
use this port for an Electric fan temp switch ?. I like the electric fan
idea but I'm not thrilled with the switch arrangements that I have seen so
far (attach to radiator fins, T adapter in top hose etc). Are there fan
switches that would fit and work in this port ?

Another question.. do all electric fans need a relay or is it just the ones
with high current demands ?. If I go down this path it will be a puller fan
used to replace the mechanical fan so it would be a 16 inch model and I see
some of these are rated in excess of 16 amps.
