    Here you go....hope this helps....Jim........Install NEW lower intake manifold bolts.

    The torque specification is a 2-step process; tighten the vertical lower intake manifold bolts (the four middle ones) to 7 Nm (62 lb in). Tighten the diagonal lower intake manifold bolts (two on each end) to 7 Nm (62 lb in). Tighten the vertical lower intake manifold bolts (the four middle ones) to 13 Nm (115 lb in). Tighten the diagonal lower intake manifold bolts (two on each end) to 25 Nm (18 lb ft).

    Upper Intake Manifold


    Tighten Bolt/stud 25 Nm (18 ft. lbs)
