Ensure that all of the turbocharger inlet and outlet ports are clean and free from restrictions. The turbocharger shaft must rotate freely.
If the studs (17) were previously removed, install the studs into the exhaust manifold. Install a new gasket (23) over the studs (17). Note: Do not use any sealant on the gasket (23).Note: Do not use the actuator rod of the wastegate to lift the turbocharger (1).
Position the turbocharger (1) onto the exhaust manifold.
Install the washers (18) and install the nuts (19). Tighten the nuts to a torque of 25 N m (18 lb ft).
Lubricate the bearing housing of the turbocharger (1) with clean engine oil. Apply the lubricant through the oil supply port (24).

Clean the oil supply tube assembly (8) and the oil drain tube assembly (11). Inspect the oil supply tube assembly and the oil drain tube assembly. If necessary, replace the tube assemblies.
Position a new joint (14) and the oil drain tube assembly (11) onto the bottom of the turbocharger. Install the setscrews (13). Tighten the setscrews to a torque of 10 N m (7 lb ft).
If necessary, position a new joint (10) and the oil drain tube assembly (11) onto the cylinder block. Install the setscrews (12). Tighten the setscrews to a torque of 10 N m (7 lb ft).
Position the new washers (2) and the oil supply tube assembly (8) onto the turbocharger (1). Install the banjo bolt (3). Tighten the banjo bolt to a torque of 18 N m (13 lb ft).
If necessary, install a new O-ring (9) and the oil supply tube assembly (8) to the cylinder block. Install the setscrews (7). Tighten the setscrews to a torque of 10 N m (7 lb ft).
If necessary, install the spacer (not shown) and install the setscrews (not shown) to the tube clips (6). Torque the setscrews to 10 N m (7 lb ft). Note: Ensure that the oil supply tube assembly (8) does not come into contact with any other component when the assembly is installed onto the engine.
Clean the mating surfaces of the exhaust elbow (21). Position a new gasket (20) and the exhaust elbow (21) on the turbocharger (1). Install the setscrews (22). Tighten the setscrews to a torque of 32 N m (24 lb ft).
Install the set screws (15) and install the support bracket for the turbocharger (16). Tighten the setscrews to a torque of 25 N m (18 lb ft).
Ensure that the inlet hose (5) is clean and free from defects or restrictions. Loosely install the hose clamps (4) to the air inlet hose (5). Install the air inlet hose to the connection of the inlet manifold and to the inlet of the turbocharger. Tighten the hose clamps. Note: Do not use oil or grease in order to install the air inlet hose. In order to install a new air inlet hose, lubricate the connection of the inlet manifold and lubricate the inlet of the turbocharger with a solution of water and 5% soap.
Position the exhaust pipe onto the exhaust elbow (21). Refer to the OEM information for the correct procedure in order to install the exhaust pipe.
