The shroud is important when the fan (either a clutch, straight mechanical or electric) is engaged and pulling air. It allows the fan to develop the proper suction to draw the right flow of air thru the resistance the radiator (and the a/c condenser, if so equipped).It is important that the fan is centered in the shroud as well. Especially since all these fans under discussion are axial flow, which are far inferior to centrifugals when it comes to pressure developement.

Please notice that I'm NOT getting into the clutch vs. electric contraversy.

I forgot to mention that shrouds are very good for keeping your digits where they belong. I've heard it said that you can stop a clutch fan with a bad clutch with your fingers while the engine is idling. I'll NEVER even try to do that; my hunt and peck style typing would definitely suffer from any mishaps./wwwthreads_images/icons/tongue.gif
