Fan cut-in temp
How do you choose the temp at which aftermarket electric fans should cut in?
Car is '68 Mustang, 392 stroker, GT40 ally heads, ceramic coated headers, Edel 750 carb. Cooling system is BeCool ally rad (direct fit), Edel water pump, twin Spal 11" fans built into a shroud module. I am using a two-stage thermostatic switch to control the fans. The car is stock inside so the temp gauge is pretty much useless. I have a 195deg thermostat, so I'm guessing the first fan should come on soon after this opens - is this correct? And second fan at maybe 10deg above that?
