Thread: Lower tensioner bolt missing

Hey guys, I need some help for a buddy of mine at work.

He's missing the lower bolt of the tensioner. I'm assuming it's the lower bolt that holds the shock-like thingy to the tensioner assembly, since he has no tension. I haven't seen it in person, so that is what I gather. Does anyone know the bolt size\thread for that bolt? He's called everyone he knows to call and I'm basically his last resort, lol. Anybody able to help out?

Thanks in advance.

Take the other bolt out go to the store and match the thread they are all the same

They're the exact same? I'll bring it up to him and see what he says. I'd assumed he'd be smart enough to figure pull the other one if they were the same, but who knows. Either way, thanks.

Length might be different, but thread is the same. You would be suprised in the bay how many threads are the same, I have used the strut nuts for a couple things when the other nut fell into the bay black hole.

Shock like thing to the tensioner assembly?

There's bolts that hold the accessory tensioner bracket to the engine. The tensioner itself doesn't unbolt or com off the bracket assembly.
The SC tensioner has a nut that holds it on stud over a nut that holds it to the cast iron bracket.

The bottom bolt in that picture, I believe.

any impala's in the local junk yards?

gm might have a exploded view/parts list for that

He says he called everyone he knows to call in the state(and Kansas), and every junkyard that has something with this tensioner said it was already missing this bolt. I brought up pulling the top bolt out and he said it was a super PITA to get to, and that you have to pull the bracket. I wonder if Alldata would have the info? I guess I'll have to check, lol.

Dammit..call me Scotty.

Does it look like this?http://www.grandprixforums.net/threa...4-Belt-removal

Im pretty sure its a metric size though nothing to complicated

Yep, that's the one.
