:

• Tighten nuts the No.1 to No.4 in two steps.

• The numerical order No.9 to No.12 shows the second step.

3. Install remaining parts in the reverse order of removal.

Inspection

INSPECTION AFTER REMOVAL

Surface Distortion
• Using feeler gauge (A) and straightedge (B), check the surface distortion of exhaust manifold mating surface in each exhaust port and entire part.

Limit : Refer to EM-130, "Exhaust Manifold".
