Intake Manifold

Lower Intake Manifold






Caution: 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.

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

1. Apply sealer to the lower intake manifold bolt threads.
2. Install the lower intake manifold bolts.
3. Tighten the lower intake manifold bolts in the sequence shown.
