Can any of the more techy types out there help with this one.....
Next to the thermostat housing on the manifold of my 2000 Berlina (which is of course the same as the rest of the carb. engined 105 series Alfas

) there's a brass screw-in plug for venting the upper galleries of the engine when filling the radiator with coolant. It would be a perfect place to screw in a thermal switch for my electric cooling fan conversion

. Does anyone know the thread size of this orifice so that I can source a switch of the same thread to fit into it????
