Removing manifold heat shield
Can you take out the heat shield just below the manifold.
I got the 3 bolts off, but I can't seem to get it out of its place.
Do you slide it up?
Do you have to take any other parts out to make room?

why you want to remove the heat shield? It is a very very tight space, I don't know who have done it. I have seen mine when I was under the car when I was changing out all the O2 sensor. It's not a lot of room to work with.

I replaced my entire exhaust last year from the pre cats back, and the manifold heat shield in the back was a PITA to remove. My bolts had rusted badly, and stripped so I ultimately ended up drilling them out, and could no longer use the heat shield as it was in bad shape. There is no easy way to remove, you just have to remove the 3 retaining bolts and then wiggle out from above or below. The heat shield is bent and ind of wraps around the manifold so you have to force it. It helps to remove the square retaining bracket up against the firewall that protects the power steering lines, and you'll also have to carefully manipulate around the hoses at the top if you go out that way. I do remember that this took me a long time to do, and that removing the heat shield was a PITA!

I use antisieze and put a dab on it. This keeps the bolts from rusting in. But I can only imagine.
the precat bank2 should have the same size screws in it attaching the heat gaurd.
but these screw holes go through into the catalyst so you can't remove them.

I'm in the same boat. The front heat shield looks manageable, but the rear shield looks like a nightmare.
It looks like you have to remove the intake manifold to access the 3 heat shield bolts. Is it possible to remove the rear heat shield without removing the intake manifold?
