Intake Manifold: Installation

WARNING: This page is about a different car, the 2012 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.

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 if found, install a new intake manifold. Failure to follow these instructions can result in engine damage.

NOTE: Clean the sealing surfaces with metal surface prep. Follow the directions on the packaging. Inspect the mating surfaces.

Using new gaskets, install the intake manifold.
- Tighten the 6 intake manifold bolts in the sequence shown in illustration in 2 stages.
  - Stage 1: Tighten to 10 Nm (89 lb-in).
  - Stage 2: Tighten an additional 45 degrees.
