As for the needing an entire shroud debate, I do agree with the point Bjhines is trying to make, but it's just useless nitpicking of the cooling system. Regardless if half the radiator has a shroud, or if the entire radiator has a shroud, all of those little tubes all end up going to the same place and out the same hose. so what if a small amount of radiator surface area isn't covered by a shroud, as long as the fan pulls enough air to lower the coolant temp enough so that when it mixes with the rest of the coolant the temp doesn't rise a consider amount and still in the nominal range, then there isn't a problem.
You can nit pick it all you want, but if it's not going to show any real world noticeable effects, then it's useless to argue them. If it works, it works. Who cares how it's done.
