NOTE:
Lubricate the turbocharger with clean engine oil before installing. Pour 0.1-0.2 oz (3-6 cc) clean engine oil into the oil feed hole before installing the oil feed line on the turbocharger. Turn the compressor wheel by hand to lubricate the bearings in the turbocharger.
NOTE:
Inspect for foreign material in the intake and exhaust systems leading to and from the turbocharger. Clean the inside of the intake and exhaust system for the turbocharger.
- Install the turbocharger on the right exhaust manifold. Apply a small amount of high temperature Anti Seize Compound (GM 1052771) on all the threaded fasteners for the turbocharger. Apply a small amount of RTV Silicone Sealant (GM 12346240) to a clean turbocharger compressor inlet and the upper intake manifold connection to prevent oil leakage.
- To complete installation, reverse removal procedure. Tighten fasteners properly. See TORQUE SPECIFICATIONS . Start and run the engine at an idle for at least 2 minutes after completing the installation of the turbocharger. While running the engine, check for any oil leaks at the oil feed or return line and repair as necessary.
NOTE:
In order to ensure heat shield clearance, locate the exhaust pipe clamps as shown. Tighten the clamps at the exhaust manifold end first. See Fig 1.
- Apply Anti-Seize Compound (GM 1052771) on all threaded fasteners connected to the turbocharger. Install new turbocharger seals to the engine block. Install the turbocharger assembly to the engine block. Install the turbocharger mounting bolts.
- To complete installation, reverse removal procedure. Tighten fasteners properly. See TORQUE SPECIFICATIONS . Run the engine at an idle for at least 2 minutes after completing the installation of the turbocharger. This will allow the oil to lubricate the bearing inside the turbocharger. Check for leaks.
