Radiator shroud rattle

Check all the fastners you can see then lie on your back and check the ones on the bottom of the covers, they all work themselves loose i removed all of mine(one at a time ) and applied some locl-tite to each one.
 
Rubber tape between the screen and radiator. Also the hex heads are fitted through a brass spacer that can rattle, some double sided tape between the spacer and inside of the cowling will hold them in place and stop the rattle.
 
My screen stopped rattling after installing Flips stainless "Rocket" grill over the top of it.

I would expect that also just giving it a slight bend would take the play out of it too, just enough to stop it from rattling.
