Upper Radiator Hose Contact With Upper Shroud

I have been investigating the life of the cooling fan on my 8.1 and found numerous old threads on moving fan shrouds and loss of the shroud side seals. In some case, loss of the seals or the moving shroud ended in catastrophic loss of the fan blades, radiator and other parts.

Today I went out and found one of my side seals to be missing (right side) and the other was there but really wasn't securely attached. Worse, I found the upper shroud left bolt near the upper hose connection not holding anything because the corner of the shroud was tore out of the shroud. I used a metal clamp to squeeze the shroud against the frame hoping that will secure it but then saw a post alluding to the upper hose movement and shroud damage. In the photo below, you can see there is a square protrusion on the upper shroud that I think might be there to support the hose. However, I am now wondering if this is the source of my broken shroud.

Does anyone have any insight to this?

My current plan is to get a rubber/metal door sweep (for a garage door) and use that for the side seal by bolting to the side of the shroud. Hoping this will not only seal the side from air bypass but also make the entire shroud more rigid.

Just my opinion, but i would think the hose does not need to be supported by the shroud, and if the upper radiator hose has been replaced before, it might not be in the proper position, in other words the hoses are pre bent, and maybe just by turning the hose it would allow space between the hose and the fan shroud.

Another thing to look at, the holes for the bolts that are used to keep the shroud in place maybe wallowed out and allowing your shroud to move.

Kevin, I picked up some aluminum and rubber door sweeps today, going to check fitment tomorrow before opening so I have the option of returning to Home Depot. There is a slot on the opposite side that fits the width of the side of the shroud almost perfectly.

Did you do anything to the driver’s side to keep it from coming out?

It is a relatively new Workhorse hose from Ultra RV Products. There is really no place else to move it. Just for future reference, I tried one of the non-Workhorse hoses and it didn't fit good at all and also didn't have the protective sheath, which you need on this hose due to all the rub points. I ended up taking that back and ordering the correct workhorse parts.
