Intake Manifold Sealing
INTAKE MANIFOLD SEALINGThe intake manifold gaskets are one-piece fiber gaskets with a molded-on silicone beads applied from the
manufacturer.
1. Clean all surfaces of intake manifold and cylinder heads.
2. Carefully install the intake manifold gaskets using plastic alignment pins.
3. Install intake manifold and twenty bolts and torque to 1 Nm (10 in. lbs.). Then torque bolts to 22 Nm(200 in. lbs.) in sequence. After intake manifold is in place, Refer to Exhaust System and Intake Manifold to complete Intake Manifold Assembly.
4. Install exhaust manifold gaskets.
5. The lower center and outer bolts must be in- stalled first to ensure proper alignment of exhaust manifolds and tighten bolts to 22 Nm (200 in. lbs.). Install the stud bolts in the upper 5 positions of the manifold.
6. Install heat shields on exhaust manifolds. Tighten all attaching nuts to 5.6 Nm (50 in. lbs.).
7. Adjust spark plugs and install the plugs.
