I'm looking for the exhaust manifold heat shield for my 07 Hummer H3 3.7 L5. Used is fine but I've been unable to find this part anywhere. Starting to think I'll have to have one made by a machine shop.
Any assistance highly appreciated.
Does that part number cross over to any other GM model with the same engine family?
Chuck Tobias, that's a good question that I don't know how to get the answer to. Are you able to point me in the right direction to begin that research?
@thegees1989 You can try looking up the part number online via a web search for Hummer parts sources. You may be able to look it up at sites like the one below:

Even if the part is out of stock once you have the GM part number you can do an internet search on it to see if anything pops up as being available for your Hummer or other GM vehicles.
You may or may not find anything useful but if you get lucky you might find something.
@imperator I'm not sure honestly. I'm in the middle of doing a build on this H3 to bring it back to life so working through issues one by one. The exhaust manifold has a crack in it plus the heat shield has all kinds of damage from someone's misguided efforts previously.
I spent 8 hours yesterday looking online for a replacement shield to no avail. I don't have a way to pull a part off an H3 in a junkyard or I'd do that. So....I'm looking at putting Header Armor on the manifold itself. Seems to be the only option I can come up with.
can you just bend it back into shape? it doesn't need to be perfect
@imperator The shape isnt awful, it's the bolt holes. They're so distorted I'm not sure how to reattach it now that it's off. I'll ask my tech what he thinks. It'd be fantastic if bending to reshape would fix the problem.
Some big fender washers?
