Header question

[srt8rose]

Does anybody have a shop manual or happen to know the torque setting for exhaust manifold/header bolts? I don't feel like guessing with aluminum heads. 06 300c srt8 kooks long tubes. Thanks for any help.

i cant find it in the service manual but tighten them until there sung thats it, drive it and check to see if there tight again within 1-2 days of driving

Thanks I'll have to do that. I'd have a hell of a time getting a torque wrench up there anyway w/o extensions and knuckles

31 newton meters...or 23 pound feet...or 270 pound inches.

You really should go to alldatadiy.com and get an account. I have both my car and my wife's through them, and it's paid for itself many times over. You'll want to know the right sequence to tighten the bolts, too, right? There's a nice schematic for it in alldata's online manual.

The spec is 23 ft-lbs, but there's also a recommended tightening sequence.

Left side

8 3 2 4

Right side

Thanks everybody just had a bolt come loose and wasn't sure of the torque to re-secure it.
