Does anyone know how to adjust (or make adjustable) the temperature at which the radiator cooling fan turns on. I would even like to have the opportunity to make it manual if I desire? Any help would be much appreciated.
I think there are several here that have done just what you are asking. Try doing a search or posting in the "mods" section and you will have more info than you want!
Saw an article sometime ago on a cheap way to do it. They added a Hayden switch that you could set the temp on and had a sensor that you put in between the radiator fins. They wired it up so it was in parallel with the factory setup so that all it did was turn the fan on earlier than the brain would. I can't find the article now. Maybe 1934 remembers it because I am pretty sure I had read it from my T-Bird days.
