fan shroud needed

You ought to consider switching over to an electric fan. You'll have more room under the hood and just may pick up a few more mpg like I did.

That's a good suggestion, thanks. I don't know how critical the shroud is as the temps didn't get too high after the incident. I won't know until I hit some of those nice hills in the Blue Mtns. next fall with my trailer on. I'm pulling a 9000# fifth wheel & at the peak pull, it's hitting about 3/4 of the way up the temp gauge with the tranny temp around red line for a few minutes. It seems to be a well designed cooling system, so I may not need the shroud.
