Lower Intake Manifold: Installation

WARNING: This page is about a different variant/trim than selected.

NOTE: If the engine is repaired or replaced because of upper engine failure, typically including valve or piston damage, check the intake manifold for metal debris. If metal debris is found, install a new intake manifold. Failure to follow these instructions can result in engine damage.

Using new intake manifold and thermostat housing gaskets, install the lower intake manifold and the 10 bolts.
