what torque should the 10 bolts to the exhaust header be? I think I read somewhere 10lbs, but that seems low!

 

Exhaust Manifold to head nut torque is 14 N.m -- 124 lb in!

10 lb ft will do....remember they are small and go into aluminum!!!!

 

thnx . . .

 

Tighten
Tighten the nuts in the sequence shown to 14 Nˇm (10 lb ft).

8 6 1 3 2 9
7 4 5 10

 

cool, i appreciate the input

how about the header to downpipe torque, cause those were a B@#CH to get off!

 

DP to exhaust manifold nuts - 50 N.m (37 lb ft)

H02S sensor - 30 N.m (22 lb ft)

Heat shield studs -- 22 N.M (16 lb ft)

 

Nobody cares about those




The DP nuts were a bitch to get off because of corrosion.

 

^ Very good! People need to realize how important it is to tighten them in these steps. Its always a good idea to go:

8 6 1 3 2 9
7 4 5 10

Then go around and double check in the same order.
