Fan Shroud Noise ???
 

So I figured out that the cause of the noise when I start my car is the loose fan shroud. There is no way to tighten this so what do you suggest? My husband is going to try and shimmy 2 plastic parts so that it isn't loose.

there is a way to tighten it, just use a wrench and it is reversed thread.

Is the whole fan shroud loose or just at the top? The shroud hooks in and has some plastic expanding rivets as fasteners.

Its the fan itself that is reverse treaded and it takes a 32mm wrench.
