Ensure that turbocharger (4) is clean and free from damage. Inspect the turbocharger for wear. Refer to System Operation, Testing and Adjusting, "Turbocharger Inspect" for more information. If any part of the turbocharger is worn or damaged, the complete turbocharger must be replaced.
If necessary, test the wastegate actuator for correct operation. Refer to System Operation, Testing and Adjusting, "Turbocharger Inspect". If the wastegate actuator is damaged or the wastegate actuator does not operate within the specified limits, the complete turbocharger must be replaced.
Clean the gasket surfaces of exhaust manifold (16). If necessary, install studs (17) to the exhaust manifold. Tighten the studs to a torque of 18 N m (160 lb in).
Position turbocharger (4) on exhaust manifold (16). Note: Ensure that the turbocharger is correctly oriented.
Install nuts (18). Note: Support the turbocharger as the nuts are installed.
Tighten nuts (18) to a torque of 44 N m (32 lb ft).
