Intake Manifold: Specifications

Upper Intake Manifold





Set the upper intake manifold onto the lower intake manifold.
Apply threadlock to the upper intake manifold bolts/stud threads. Refer to Sealers, Adhesives, and Lubricants.

Install the upper intake manifold bolts (1, 2) and stud (3).
Tighten the bolts/stud to 25 N.m (18 lb ft).

Lower Intake Manifold





Notice: Maximum gasket performance is achieved when using new fasteners, which contain a thread-locking patch. If the fasteners are not replaced, a thread locking chemical must be applied to the fastener threads. Failure to replace the fasteners or apply a thread-locking chemical MAY reduce gasket sealing capability.

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

Apply sealer to the lower intake manifold bolt threads. Refer to Sealers, Adhesives, and Lubricants.
