try tightening it up. if that doesn't eliminate the rattling, just get a new one. the front one is about $50. i had mine off for a while, and it DOES make a different in engine bay heat. without the heatshied, it will get hotter than hell. with it, it will just be very warm.batboyx on Aug/27/02 said:I dunno what to do, they're going to remove it because it's rattling like a b#tch heh. So what should i be doing ?
