Broken Exhaust Manifold Heat Shield Bolt

[Show Links]

Below is a diagram that shows a bolt which I broke, while trying to remove my manifold heat shield on the passenger side. The bolt I am referencing in the diagram is at the very bottom of the picture on the right hand side. I am hoping the only function of the bolt is to hold the heat shield in place. Can anyone verify if that is the only purpose of this bolt? I plan on trying to extract, but I would like to know how big a problem I have.

Thanks for any help.

The image isn't much bigger than the thumbnail. How about posting pics of your truck?

Yes the heat shield is all it attaches. The only other thing I have seen bolted there was a dipstick but most bronco dipsticks attach to one of the larger exhaust port bolts so it must have been something other than original.

Yes it's the shield bolt. It's only about 1/4" diameter and about the same length.

Thanks, that's a relief. Now I need to get it out of there.
I appreciate the help.

Fortunately its the passengers side exhaust manifold. Go to the wrecking yard and get another one. most of the 70's ford 302 had that same manifold. The drivers side is much tougher as there was a variety of manifolds used through the different car lines.

If you are game take off the manifold and drill out the broken bolt and re-tap. The threaded hole is a through hole and not blind.

Thanks, I think I'll finish up the final restoration projects, return to the manifold and drill out the bolt as you suggested. Thanks for taking the time to include the pic showing the bolt as a through hole. Very helpful and relieving.
