Electric fan conversion
So I already have a fan that will fit in the factory shroud with a little creative persuasion and I know it flows enough CFM to do the job, I've just got one question. Why do I see everyone using an aftermarket fan controller to do this install, instead of just getting a GM temp switch that threads into the head or intake manifold? Seems like a much simpler solution, right? Or is there something I'm not thinking about?
