Viscous fan is a POS, if that thing packs up it takes your radiator out, hoses, and stuffs your bonet up beautifully. when it goes it goes with an epic boom!
Electric fan is way better, I would much rather have an electric fan than my POS viscous noisy, energy draining time bomb of a fan!
Plus when your viscous fan switches on it sounds like your driving a truck, it stops your car from reving as freely!
