Install exhaust manifold assembly (4) in the reverse order of removal.
Apply Tooling (A) to male ends of manifolds (9) and (11).
Apply Tooling (B) to male ends of tube assembly (6).
Apply Tooling (C) to studs (12) and (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.
Install gaskets (8) so that the tabs are down.
