Exhaust Manifold Support Bracket Bolt

[bennyc]

While replacing my exhaust manifold I found the bolt/stud that secures the exhaust manifold support bracket to the engine was missing.
So I am not sure if I should be looking for a stud or a bolt. Can anyone help clarify what I need to secure the supporting bracket to the engine?

In the diagram below #19 is a bolt (Stud?) for the bracket:

In my Haynes manual this illustration shows a stud?:

Thank you VNT. I purchased a bolt and washer at the store today and will report the outcome later today when I get a chance to install.

General information about fasteners for exhaust manifolds.

It is very important to get fasteners that have a minimum rating in strength and material for replacements. Washers or lock washers used must be specifically designed for high heat use automotive or engine exhaust manifold areas.

Thank you all for the information and help. The M10-1.5x22 bolt fit perfectly BUT unfortunately I could not get the hole in the bracket to line up. When I screwed in the bolt/stud to the manifold and bracket then tried to line up the the engine bolt hole with the bracket I could not get it. Tried using the factory bracket and the bracket that came with the manifold. I guess the Dorman manifold is just a few millimeters off from factory.


Anyone have any ideas/suggestions?

Can you bend the bracket..or maybe jack the engine up or down a little..??

Drill the hole in the bracket out just a little. The washer should take up any space.

Good idea. I am going to do that.

I tried bending but just don't have to tools to do it. Though your idea about jacking up the engine got me thinking. Maybe the engine will sit ever so slightly low if my middle motor mount is bad? I Recently installed new tower and lower torque struts and adjusted the engine height per my Haynes manual. However, there is a fare amount of vibration at idle both in gear or neutral. I have been planning to, and do have, the middle motor mount and the transmission mount will arrive tomorrow.

So, I'll drill the hole, mount and get that manifold support installed. Then I'll see if the engine sits any differently once I get those mounts installed.

Thanks again for the suggestions.

Mine was tighter than a tight thing when I done my rebuild, and that was with stock oe parts. I had to fit the bracket with the manifold split from the exhaust to get it on there. Once it was buttoned up, the exhaust lined up with the flange perfectly

Good point I didn't even try that but will keep that my back pocket.

Oh well, I did expand the size of the existing hole vertically and was able to secure the bracket. So I will just go with that.

Thanks everyone for your insight.
