Install the exhaust piping on the turbocharger. Position the turbine housing with the exhaust pipe in order to prevent binding.
If necessary, connect the air pipe assembly to the turbocharger. Install clamp (1). Position the compressor housing with the air pipe assembly in order to prevent binding.
If necessary, connect the air inlet elbow to the turbocharger. Install clamp (6). Position the compressor housing with the air inlet elbow in order to prevent binding. Tighten clamp (6) to a torque of 8.5 ± 1.0 N·m (75 ± 9 lb in).
Tighten the nut on the turbine clamp to a torque of 12.4 ± 0.6 N·m (110 ± 5 lb in). Do not overtighten the nut.
Tighten the nut on the compressor clamp to a torque of 12.4 ± 0.6 N·m (110 ± 5 lb in). Do not overtighten the nut.
Lightly tap around the diameter of turbine clamp with a soft hammer. Tighten the nut on the turbine clamp to a torque of 12.4 ± 0.6 N·m (110 ± 5 lb in). Do not overtighten the nut.
Lightly tap around the diameter of compressor clamp with a soft hammer. Tighten the nut on the compressor clamp to a torque of 12.4 ± 0.6 N·m (110 ± 5 lb in). Do not overtighten the nut.
Tighten the locknuts from Step 5 to a torque of 55 ± 5 N·m (41 ± 4 lb ft).
Apply Tooling (A) to the bolts for tube assemblies (4) and (3). Install the gaskets and connect tube assemblies (4) and (3) to the turbocharger. Install the bolts.
Install the O-ring seals on hose assembly (5) and hose assembly (2). Connect hose assembly (5) and hose assembly (2) to the turbocharger.
Fill the cooling system with coolant to the correct level. Refer to Operation and Maintenance Manual, "Refill Capacities" for more information.
