I figgerd as much, I mean it just had to be. And PLEASE don't think it was a dig, 'cause it sure wasn't.
As the fan option is plainly read on the sticker, we might open that for discussion too. Just to be sure I don't confuse the masses. I can't afford to loose more stars! What I truely wonder is if the FLEX has to do with the energy behind it. Seeing as how it is a clutch type fan, it COULD stand to reason the term comes from the different levels of torque at different temperature ranges (on a thermostatic clutch) or engine speeds (with a centrifugal clutch).
