Viscous Cooling Fan Assembly for the 4.0L and 4.6L V8 petrol engines, part of the engine cooling system. The assembly combines the engine-driven cooling fan with a viscous (fluid) coupling that varies fan speed with temperature. At low temperatures the coupling slips to reduce drag and noise; as the engine warms the coupling engages and the fan draws additional air through the radiator. It mounts on the water pump drive behind the radiator. Show more
