sides/corners of the radiator? It is these areas that get all bent up by road debris and block air flow. There is not much cooling margin for our Z32's. My 280ZX's could have the radiators 1/2 blocked and the engines would keep from overheating...this is not the case for our Z32's. Just because a piece of paper can be sucked to the radiator is not an indication of acceptable air flow...IMO.
