3.Clean the mating surfaces of the exhaust manifold.If necessary, install studs (15) to the exhaust manifold. Tighten the studs to a torque of 18 N·m (13 lb ft). Install a new gasket (20) over the studs.

4.Position turbocharger (4) onto the exhaust manifold. Install nuts (17) and tighten to a torque of 25 N·m (18 lb ft).

Note: Do not use the actuator rod of the wastegate to lift the turbocharger .

5.Ensure that tube assemblies (10) and (13) are clean and free from damage. If necessary, replace the tube assemblies.

6.If necessary, position a new joint (11) and tube assembly (10) onto the cylinder block. Install bolts (9). Tighten the bolts finger tight.

Position a new joint (7) on tube assembly (10).

Align tube assembly (10) to the bottom of the turbocharger. Install bolts (8). Tighten the bolts finger tight.Tighten bolts (8) and (9) to a torque of 10 N·m (89 lb in).

7.Lubricate the bearings of turbocharger (4) with clean engine oil through oil inlet port (16). Rotate the shaft of the turbocharger in order to distribute the lubricant.

8.Install a new O-ring seal (12) to tube assembly (13). Position tube assembly (13) against the cylinder block. Install bolts (14). Tighten the bolts to a torque of 10 N·m (89 lb in).

9.Install new washers (3) and banjo bolt (2) to tube assembly (13). Position tube assembly (13) onto turbocharger (4). Tighten the banjo bolt finger tight.

10.If necessary, install the spacer and install the fasteners (not shown) to tube clips (6). Torque the fasteners to 10 N·m (89 lb in).

11.Tighten banjo bolt (2) to a torque of 18 N·m (13 lb ft).

Note: Ensure that the tube assembly does not come into contact with any other components.

12.Clean the mating surfaces of exhaust elbow (19).

Position a new gasket (18) and exhaust elbow (19) on turbocharger (4). Install allen head screws (21).Tighten the bolts to a torque of 32 N·m (24 lb ft).

13.Ensure that inlet hose (1) is clean and free from defects or restrictions. Loosely install hose clamps (5) to air inlet hose (1). Install the air inlet hose to the connection of the inlet manifold (not shown) and to the turbocharger. Tighten the hose clamps.
