Just finishing up putting everything back together after replacing the head gaskets, and I have this metal piece that I can't find a spot for. I have a note that it goes on the driver's side, but that hasn't been helpful. Anyone know where it goes? Thanks
Garbage, I kind of agree. I have solved ao many issues by removing heat shrouds over the years.
all they do is conduct heat, then radiate it at from a solid source, which is more likely to burn wire insulation than if it wasn't there to begin with. Other reasons I've removed them...
Rattles,
sharp edges cutting through wires,
trapping exhaust heat in starter motor area leading to burnt out starter
They really are a design flaw in most cases. But some under the cabin and near fuel lines are best left in tact, only if they are the padded or insulated type. The one in the pic is just a waste of space.
I don't think these are heat shrouds. They mount in the wheel wells and act as a splash shield - minimizing the crap thrown from the wheel side. You've got a left and a right there; look for the mounting holes outboard of the slave cylinder and outboard of the manifold to headpipe connection. I think they are well worth re-installing.
I'll wait for Labow to stroll out to his rig and re-install. If he was pulling his heads while the engine was in the truck, then this piece of metal came off the driver's side frame rail so that he could disconnect the exhaust.
Installed Uninstalled
I'm just guessing as to what the Toyota engineers were thinking when they designed the part, but I'll stick with my trash shield theory since a) there is one on each side and b) it doesn't line up with the exhaust.
Not sure why I'm invested in this thread. You show me a Toyota part number and nomenclature with heat shield and I'll concede - otherwise I'll stick to my opinion. If I have a garage sale and call my rocking chair a hemorrhoid massage therapy tool, that doesn't make it a piece of medical equipment. There is no heat source close to this piece of tin (or its sister on the other side of the engine bay) and nothing sensitive outboard of it. At the end of the day, hopefully the OP knows where it goes.

It's a heat shield for the down pipe from the manifold by the brakes. It is garbage because it's only in the way of everything when you are working on it and it shield the hard metal brake line coil from exhaust heat. It doesn't make any difference I threw mine away. It does not stop mud as it is too far back from the tire.
Garbage? Well, you can take the opinion of some real automotive engineers who designed a truck that's already lasted you about 25 years. Or you can listen to some anonymous posters on the internet, some of whom candidly admit they don't know why the part was installed in the first place. Your choice.
Sure wish you would have quoted the gent who called it garbage as well as me...as it is I'll be dusting off that slice of humble pie. My mom always told me that opinions were like cowboy hats - every a$$hole has one (and I've got a couple). Scope103, thanks for the research and the definitive answer.

Excellent Scope103!
This is the diagram I was looking for when I suggested that someone take a picture of the insulator / heat shield installed. I didn't think to look in the brake tube section!
Just a quick FYI. Most splash shields are plastic. They don't tend to make splash guards out of metal, as metal and water and mud aren't the best of friends. But I still stand by it, it's really there as it's someone's job in engineering and design to ensure ever possible failure point is eliminated. It's very very harf to boil brake lines from an exhaust which is more than a handwidth away.
of course, if u know where it goes, put it back to keep it stock, but the reality is, it's just added weight and complication.
As I was the one that called it garbage I can say my brake lines have not boiled and have discarded it. I also was the first to properly identify it as the brake line heat shield. Do what you want but assholes on here know what they are doing as well
