3. Install exhaust gasket (4) and exhaust sleeve (6) on exhaust manifold (5) .

4. Apply Tooling (A) on the exhaust manifold studs.

Note: Discard the locknuts after use. Use new locknuts for installation.

5. Attach a suitable lifting device on turbocharger (1) . The weight of the turbocharger is approximately 39 kg (86 lb). Install locknuts (3) . Do not tighten the locknuts at this time.

6. Install the exhaust piping on the turbocharger. Position the turbine housing with the exhaust pipe, in order to prevent binding.

7. Install the O-ring seals on the air pipe. Apply Tooling (B) to the O-ring seals. Install the air pipe on the turbocharger. Position the compressor housing with the air pipe in order to prevent binding.

8. Tighten the nut on the turbine clamp to a torque of 14 ± 1 N·m (10 ± 1 lb ft). Do not overtighten the nut.

9. Tighten the nut on the compressor clamp to a torque of 14 ± 1 N·m (10 ± 1 lb ft). Do not overtighten the nut.

10. Lightly tap around the diameter of turbine clamp with a soft hammer. Tighten the nuts on the turbine clamp to a torque of 14 ± 1 N·m (10 ± 1 lb ft). Do not overtighten the nut.

11. Lightly tap around the diameter of compressor clamp with a soft hammer. Tighten the nuts on the compressor clamp to a torque of 14 ± 1 N·m (10 ± 1 lb ft). Do not overtighten the nut.

12. Tighten locknuts (3) to a torque of 55 ± 9 N·m (41 ± 7 lb ft).

13. Install the O-ring seals on tube assembly (5) . Install the tube assembly.

14. Install the gasket and tube assembly (2) .
