I see the bottom of the shroud is also missing, I work on a fleet with many GM trucks with the same fan, most of these have more than 100.000 miles on them and I have not seen a problem with the fan blades? I am in Michigan so I don't know if the Texas heat would make alot of difference or not, I would think something could have hit the shroud from under the truck and put it in the fan also, when the truck got warm and the clutch engaged if it was in contact with the shroud, boom, up here the fan shroud is a popular spot for cats to take a warm nap I have seen that, but I think you would know if that was the case.
