^^ by radiator rattle you just mean in the general area of the front grilles and such, right?

I know my car does it too, but my upper grille isn't clipped to the bumper properly. Make sure yours is.. there's 2 or maybe 3 posts that stick up out of the bumper cover that latch into the bottom of the upper grille. I can't get mine to clip in by just pushing down on it (pesky new grille isn't all broken in like my old ones were) so the rattle stays until I have time to pull the bumper cover.

 

huh...good call. 1 of the mounting points on my upper grill's busted (has been since I bought it). I'll have to take a look at that. I just remember seeinng the radiator shaking around and making a bunch of noise.

 

yeah, the radiator can shake all it wants, it's mounted on rubber bushings. unless the rubber was dried/cracked/missing it probably wouldn't be causing much of any noise. the grille on the other hand.. hard plastic on hard plastic. I'm thinkin about putting some sort of gaskety material between the upper grille and the bumper when I take the bumper off to fix the rattle just in case.

 

my custom license plate bracket vibrates where it touches the bottom grille. tis super ******* annoying

 

I'd pull the lower grille out and dremel the crap out of that little area.. just enough that it doesn't touch your bracket

 

So I played around with it some this morning (EDIT: No...not that...). I'm pretty sure that it is the upper grill. I wonder if I can get a stock 1 FS somewhere. Anyone?

 

You think yours is broken?

 

i have one, but its missing a tab

 

then i would have to not be lazy. game. set. let it vibrate
