torquing exhaust mani studs

[bertrenolds5]

Should I torque or hand tighten my exhaust mani studs? If I torque them, what should I torque them to?

You *should* torque them, but I think most of us just tighten them by hand.

[bertrenolds5]

Any idea what to torque em too? I have a dial wrench.

I would think it tells you in a repair manual.

I just tightened them to where I felt comfortable.

I think its like 56 but im got sure

[bertrenolds5]

I'll look through my chiltons but I don't think it's in there.

[Kracka]

Look harder, it should be in there :)

Nothing, I've got 18-22ftlb for the nuts and 40ftlb for the 4 bolts for the mani to turbine housing, but nothing for the studs. I might try checking the torque on the studs that are on the car right now and got with that.

I would think 56ftlb's would be way to much for a steel bolt in an aluminum head.

The studs into the head? Just turn them until the center part with no threads reaches the head and gets snug, don't overtighten because they'll strip out.

That method has worked for me in the past.

Just hand-tighten them and once it gets snug, give it a 1/4-1/2 turn to where you feel comfortable. Use some thread locker on it too.
