Lower Intake Manifold Torque and Sequence

Lower Intake Manifold Tightening Sequence:

NOTICE: Failure to tighten vertical bolts before the diagonal bolts may cause an oil leak.


Apply sealer to the lower intake manifold bolt threads.

Tighten the lower intake manifold bolts in sequence to 7 N.m (62 lb in) on the first pass.
Tighten the lower intake manifold bolts (1, 2, 3, 4) in sequence to 13 N.m (115 lb in) on the final pass.
Tighten the lower intake manifold bolts (5, 6, 7, 8) in sequence to 25 N.m (18 lb ft) on the final pass.
