I have a 240z which actually has a Champion 3 row radiator and the original plastic fan blade. When i am stuck in traffic the temperature in the temp gauge rises to 3/4. I have been recommended to get a Fan Shroud for this radiator as i am looking forward to install a Vintage Gen II Mini evaporator and Sanden 508 compressor. What kind of fan shroud shall i purchase for this radiator? Plastic or metal? Which Brand? any other recommendations? Been looking around and cant find any that could possibly fit. Anyone??
