Clutch vs. Electric Fan

Focus on getting some sort of shroud and you will fix your problem. I'm running 12.5 CR in my Hemi Dart with a mech. fan with shroud and be cool radiator and the car runs at 170-180. I even drove it in a parade this summer with the temp in the low 90's. for 45 minutes and the car did pretty good untill the end when it had warmed up to 220. I turned right when the parade turned left and 5 minutes latter the dart was back down to 180.
