Installation Procedure

1. Install exhaust manifold assembly (5) in the reverse order of removal.

   1. Apply Tooling (A) to male ends of manifold (9) and manifold (11).

   2. Apply Tooling (B) to male ends of tube assembly (6).

   3. Apply Tooling (C) to studs (12) and studs (7). Tighten studs (12) and (7) to a torque of 35 ± 5 N·m (26 ± 4 lb ft). The torque tool speed should not exceed 100 RPM.

   4. Install gaskets (8) so that the tabs are down.

   5. Install bellows (1) with the flow arrow pointing towards the exhaust cooler. Total misalignment of the bellows is 1.50 mm (0.060 inch) lateral and 1.50 mm (0.060 inch) axial.

   6. Tighten clamp assemblies (2) to a torque of 7.5 ± 1 N·m (66 ± 9 lb in).
