If necessary, install expansion joints (5) and clamps (4). Tighten the clamps to a torque of 8.5 1.0 N m (75 9 lb in).
Apply Tooling (A) to the studs prior to assembly. If necessary, install the studs and tighten to a torque of 35 5 N m (26 4 lb ft).
Position gaskets (1) and exhaust manifold (7) on the cylinder head.
Install spacers (2) and (3) on exhaust manifold (7).Note: Use Tooling (B) in at least one oversize hole per manifold section in order to align the exhaust manifolds. Do not remove Tooling (B) until removal is required to tighten the locknuts.
Install locknuts (6) on exhaust manifold (7). Tighten locknuts (6) in a numerical sequence to a torque of 20 3 N m (15 2 lb ft). Tighten locknuts (6) again in a numerical sequence to a torque of 38 5 N m (28 4 lb ft).
Install the shield assemblies on the exhaust manifolds.End By:
Install the turbocharger. Refer to Disassembly and Assembly, "Turbocharger - Install".
