If necessary, loosen the V-band clamps and separate the compressor housing and the turbine housing from the turbocharger cartridge. The following steps are for the installation of the turbocharger.
Check all O-ring seals for wear or damage and replace with new parts if necessary.
If the compressor and turbine housings were separated from the turbocharger cartridge, place the components in their original position with the alignment marks. Install the V-band clamps loosely.14. Using a new gasket (14) install turbocharger group (12) on the manifold. Position the turbocharger cartridge and housings with air pipes, exhaust pipes and oil lines so they are all aligned without binding.
Do not tighten the turbocharger mounting bolts at this time.
15. Apply 5P-3931 Anti-Seize Compound to the threads of the turbocharger mounting bolts. Install turbocharger mounting bolts (13) and the nuts and washers. Tighten the turbocharger mounting bolts finger tight only.16. Position oil drain line (11) in its original location and install two bolts and the O-ring seal. Tighten the bolts finger tight only.17. Connect oil supply line (9) at the cylinder block. Position oil supply line (9) on the turbocharger. Install the two bolts and the O-ring seal. Tighten the bolts finger tight only.18.

Install bolt (1) to connect the clip on the oil filler tube to the bracket.21. After all the components are positioned and aligned without binding, tighten the turbocharger V-band clamp nuts to a torque of 14 1 N m (10 1 lb ft). Tap the V-band clamps lightly all around, and tighten the V-band clamp nuts again to a torque of 14 1 N m (10 1 lb ft).22. Tighten bolts (5) and (11) to the standard torque value. Tighten turbocharger mounting bolts (13) to 55 5 N m (41 4 lb ft).23. Place the hood assemblies in the "CLOSED" position.
