Well, i will be getting the Jimmy back Monday with the radiator and gas tank installed. I was going to go with a straight fan, but now i am hearing that i should run a clutch fan. Also i was told, if not a clutch type mech. fan, then i should go with an electric fan setup. It seems like anyone i talk to has a diffrent answer. I'm just not sure about running an electric fan because of mud and sand causing it problems, but i like the idea of getting full air flow at lower speeds. any ideas? Thanx in advance. p.s. Running a reverse rotation water pump.
