Installation

1. NOTICE: 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.

Clean and inspect all of the sealing surfaces of the upper intake manifold.

2. NOTE: Install new upper intake manifold gaskets.

Position the upper intake manifold and install the 7 bolts.

- Tighten the bolts in 2 stages in the sequence shown.
- Stage 1: Tighten to 10 Nm (89 lb-in).

- Stage 2: Tighten an additional 45 degrees.
