Intake Manifold: Installation

  1. 1.

    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.
    NOTE: Make sure the fuel rail wiring harnesses are routed correctly.
    NOTE: Installing the 2 long bolts first will aid in installing the intake manifold.

    Using new intake manifold gaskets and coolant crossover and thermostat housing gaskets, install the intake manifold and the 12 bolts. Tighten in the sequence shown in 2 stages.

    • Stage 1: Tighten to 10 Nm (89 lb-in).
    • Stage 2: Tighten an additional 45 degrees.
