Well its 11pm and I'm drving home. All of the sudden I hear something under the hood as if something fell through and then hit the ground. There's no traffic so I park and walk back looking at the road. I find a big screw. Its warm and it has a fresh mark like it just hit, so I know its mine. The drive home was fine no more problems.

Still, first thing tomorrow morning I want to put it back in. Before I go anywhere.
Its dark so theres no way I can see where it goes. Any of you guys know?
It's a 00 Civic Si
Here's the pic. I know, I know. I should have go to the point earlier, But w/e.
Thanks in advance.

 

Can't tell the size from the pics, but would it happen to be a bumpstop for the hood when it closes along the front?

 

It's about 3.5'' long.

 

Lower alternator bolt. goes in from the passenger side of the bracket all the way through the alternator to the other side of the bracket. a 14mm head nut (10x1.25 i believe) goes on the other side. Check your top bolt/nut which is a 12mm head and also check your alternator belt tension

 

Thanks a lot for the help. Will do first thing in the morning.
