2G Best method for breaking lower exhaust manifold nuts free?

[spyder97gs]

I've got all the top ones loosened successfully so far. There are the bottom ones that can be seen from between the pipes. There are a few of them. It doesn't appear I can get to them from the bottom because of the turbo. What's the best method for breaking them free?

I haven't taken mine off in a while, but im pretty sure I did the bottom ones with a large extension on a socket wrench..

i used alot of PB blaster, a universal and an extension. just be sure to soak them in PB blaster so you dont break the whole stud off.

From the top, right? I've been soaking them several times for the past day.

If I recall, I just used a wrench. There was plenty, ok maybe not plenty, but enough room to slowly turn and remove those nuts.

I may have used a socket wrench for backup.

Just a heads up, those nuts are torqued very very low. I found out the hard way that hand tight is too tight. Stripped/broken head stud now.
Torque to spec, be precise.

Best way to do it is between the openings. Boxed rachet wrench of the appropriate size + PB Blaster + breaker bar should do the trick. The nuts are only torqued to 17lbs-inch.

standard extension you'd get in a walmart socket set (not the small 4inch one) that and 10mm socket or 12mm can't remember.

Gonna go take a look now that my other half is home to watch the little one. Thanks fellas!

The box end wrench works fine with leverage bar over it. A socket or even a universal will absolutely not work. Thanks guys!

get a long extension and 12mm and they will came off easy

That will not work, atleast on a 2G it will not. The manifold comes up to high and does now allow enough clearance for even a universal. The box end of a 12mm wrench worked great!

I use a rachet wrench it's the best way in my opinion or if you don't have access to that tool just use a wrench. (The outside ones you can get to with a deep sock and an extension but for the middle ones go through the top.)
