Today I was doing my check under the hood thing when I noticed a missing AC bolt. Then I checked all the other componets most bolts were pretty loose as well. I do not Have a FSM, can someone please tell me what size the bolt is? (please see photo) Thanks.. Mark
In the picture, from that angle, is a little hard to tell what bolt that is. If it is the bolt that goes through the brace that goes to the exhaust manifold, it is a "bolt, hex, flange headed, M12 X 1.5 X 25". If it is the bolt the goes through the rear of the aluminum compressor bracket, through the compressor and then threads into the front of the compressor bracket, it is a "bolt, hex, flange headed, M10 X 1.5 X 105". The two bolts holding the two braces (exhaust manifold & intake manifold) to the compressor are the same. Those are the only three bolts *I* see installed from the rear.
Was there a purpose to you posting, with no help? "Glad the OP found out the problem." The OP already knew the problem, that is why he posted. Besides worthless posts to drive up your post count, all you are doing is revealing your true self. You have my sympathies.
The only other one that it could be is
Item 5 8.900 Bolt HEX FLG HD (M10 x 1.5 x 105)
but I think that is the top bolt you already have. It'd be easier if you had blocked part of the picture with the "what size bolt fits here".
here's what the chevy book says
Item #11 8.900 Bolt HEX FLG HD (M12 x 1.5 x 25)
That is also what CFI-EFI said.

Item "5" is not the top bolt. Item "11" through the brace from the intake manifold is the top bolt. There are two (2) items "11". The one at the top is for the brace that connects to the intake manifold and the lower is for the brace that connects to the exhaust manifold.
