engine fan

hi, i was just wondering if any one knows why the engine fan from the 3.6 , 4.7 and 6.1, are different from the 5.7? the other engines has the curve cover over it, while the 5.7 is flat? and which is more efficient? thanks

The 5.7 uses a hydraulic fan, this is for towing capacity, its more powerful to keep up with high cooling demand and less draw on the engine... Its much more expensive to repair too
