Ensure that the exhaust manifold is clean and free from damage. If necessary, replace the exhaust manifold. Clean the mating surface of the cylinder head.
If necessary, install studs (2) to exhaust manifold (3). Tighten the studs to a torque of 18 N m (13 lb ft).
Install the turbocharger to the exhaust manifold. Refer to Disassembly and Assembly, "Turbocharger - Install" Steps 1 through 14.
Install Tooling (A) to the cylinder head in positions (X). Refer to Illustration 3.

Align exhaust manifold (3) with Tooling (A). Install the exhaust manifold to the cylinder head.
If bolts (4) and (6) have been previously used, the bolts should be thoroughly cleaned. Tooling (B) should be applied to the first two threads of the bolts. Note: Do not apply Tooling (B) to new bolts.
Install bolts (4) finger tight. Install bolts (6) and spacers (5) finger tight.
Remove Tooling (A). Install remaining bolts (4) finger tight. Install remaining bolts (6) and spacers (5) finger tight.
Tighten bolts (4) and (6) to a torque of 44 N m (32 lb ft). Tighten the bolts in the sequence that is shown in Illustration 3.
