From the 2006 service manual (get it from
http://www.mediafire.com/?tzy2jbomzjz )
Exhaust manifold nuts at cylinder head: 30 newton-meters ( 22 foot pounds) (page 9-13)
but then on page 9-15, the table says
Exhaust Manifold to Cylinder Head: 29 N-m ( 21 FtLb.)
In the quite busy table, i don't see an obvious "Intake Manifold" spec.
Ahh... page 9-68 (notice they're using INCH-pounds in the following):
Tighten (intake) manifold bolts to 16 N·m (142 lbs. in.) in a cross directional pattern beginning with the middle bolts and tightening outward to the ends.
then:
Install the rear intake manifold bolts and tighten to 16 N·m (142 lbs. in.) (Fig. 70).
(4) Install the lower intake manifold support bracket. Tighten bolts to 20 N·m (177 lbs. in.) (Fig. 70).
All they say for the Exhaust Manifold is (page 9-70):
(4) Position the exhaust manifold over to studs and tighten retaining nuts to 30 N·m (22 lbs.ft.).
...no tightening order given
