I want to replace the stock fan with an electrical fan. I was wondering if I could pull the stock fan and clutch out and just wire an electrical fan in. My question is concerning the two smaller fans just to the side of the main one. Is there any way I could wire my new electrical fan into those smaller fans. Basically, are those fans made to turn on when the block gets too warm, so that the main fan would do the same? That way I wouldnt have to pull the whole fan shroud out of the car, because I dont know how important those two smaller fans are.
