Rattle/Vibration in engine compartment!
I have noticed a rattle/vibration that is coming from somewhere under the hood of my 2009 H3, automatic. It seems to be worse when the car first starts and when it is cold outside.
It also seems to be loudest when I first hit the accelerator and then it goes away.
Sound familiar anyone???

Re: Rattle/Vibration in engine compartment!
On the bottom of the page it says 2008 and up h3's dont have a tensioner ?
I have a 2006 and it has one.
I recently replaced the belt(75K) it looked ok but changed it anyway and saved it for a spare.

Re: Rattle/Vibration in engine compartment!
Tightened everything up. Put factory filter back in. Still have the noise!
Does the 2009 H3 have a belt tensioner?
Can anyone explain how to get to and check to see if it is the heat shield? I don't even know what this is!
Thanks!
