Re: Bolt size info needed
If you're asking what wrench to use to remove it-it takes an allen wrench-not sure size-use one that fits it snug. They make them that can be used on a ratchet wrench like a socket....Hard to tell fro the poicture but it looks like it might be "buggered" up? If so try a vise grip to remove. You'll ruin the bolt but you'll get it out...(hopefully)

Re: Bolt size info needed
That is not my engine. I just lost that bolt when I took my alternator off to install headers. Looking for what size bolt to buy to replace it with.
aw hell basically I need every nut and bolt in the picture as mine are all rusted and I lost track of what is what. |

Re: Bolt size info needed
The board took care of you already here but if you need any other bolt sizes, this site has been a help to me:
http://www.torkspec.com/torkspecme.a...-5.7L-350ci-V8 Or if you have a different engine you just go to the main site, select "Engine Torque Specifications" and then choose your engine and it will give you all or most of the bolts - even for the 396, 454, 402; etc. It also has most of them for every other system on the car or truck; chassis, suspension, etc. I've checked some of these against the GM Performance figures and it seems to be generally correct; though I would recommend having another source for critical torques. I'll try to attach a pdf of the list for the 5.7 liter 350 small block below: I feel your pain regarding previous owners and stuff missing.. one bolt at a time it seems to take forever! |
