Replacing exhaust manifold; any advice?

Hello:

I am going to be replacing the cracked exhaust manifold on my 97 1.6l 5spd Corolla soon. Does anyone have any advice for me? Does anyone know what the torque specs?

Thanks for the help.

my advice is if you dont know what your doing, or how to do it then let a pro handle it...nothing worse than not knowing what your doing and making things much worse

We actually just replaced my mom's not too long ago. I came home and my dad was already a third of the way through but I finished the rest with him. My mom has a '97 automatic Corolla DX so I'm assuming that it'll be the same. Interestingly enough, her exhaust manifold had a crack on it as well...I wonder if that's common...


At any rate, you'll have to go under your car and I believe there are two bolts/nuts that connect the exhaust manifold to the rest of the system. Remove both and be careful as ours were kinda stripped when we took it off. Luckily, the new one had brand new ones so we didn't have to use the old ones.

The rest of the bolts are on top and visible so just remove them. There might be a bolt next to the alternator that will be kind of hard to get to but DO NOT loosen the alternator to get to it (it'll just be more work). Just use a regular wrench and you should be fine.

After you remove those bolts just take off the old one and put the new one on. Make sure you don't drop the gasket down the pipe on the bottom end of your new manifold during the install.

One thing that happened to us was that right after the install when we started the car, it started smoking. This is natural (or so my dad says) and will go away after a bit of smoking. Also, I don't know if this will make a difference on your car but on my friends car after he switched his, his car kept dying until he reset his computer (he has a civic though). So if you want, just take off the negative end of your battery, let it sit for a bit so that your computer will rescan everything. At any rate, it shouldn't be too bad...just maybe some hard bolts to remove due to rust.

Hope this helps...good luck...
