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.

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!

I am lucky and have a brother in-law who owns a large truck suspension and repair business.
I asked him to take out my H3 (06 adventure) to figure out all of the clanks, metallic noises, shimmies, and shakes.
He found that the rear joint was falling apart and that the drive shaft was making the noise.
My H3 has 70k miles and has been making the noise since before 50k.
My H3 has never been off road and I drive like a nun.

Have you rear and front joint checked. good luck

Default Re: Rattle/Vibration in engine compartment!

just curious, but did you ever resolve this? what was it? I ask because I have a noise and definite vibration and cant source it, though after reading here and following the tensioner link and having all ready replaced two belts in two years, i'm now fairly certain its the tensioner.
