Maybe someone can help me out with this... I finished putting the new radiator in and went to re-install the fan (not a clutch fan and the it is the OEM one) and the bolt holes wouldn't line up. So I get to looking at it and the holes aren't even there anymore. They are covered and the bolts won't go anywhere as there is no longer anything to thread in to. When the engine rotates, do those holes move (so they would not line up) if the fan were not connected to them?
