2. Drain the engine cooling system.
3. Remove the Air Cleaner (ACL) outlet pipe, LH ACL (Air Cleaner) pipe-to-turbocharger pipe, LH turbocharger bypass hose and the LH turbocharger-to-Charge Air Cooler (CAC) pipe.
4. Remove the LH catalytic converter. Carry out the exhaust Y-pipe - dual catalytic converter procedure.
5. If equipped, remove the 2 exhaust system heat shield bolts and the exhaust system heat shield.
6. NOTE: Use a 3/8 inch Jiffy-tite quick disconnect tool, such as a Snap-on(R) LDTSP4 or equivalent, to disconnect the turbocharger coolant supply tube.
NOTE: Position a drain pan prior to disconnecting the turbocharger coolant supply tube.
Using a commercially available quick disconnect tool, disconnect the turbocharger coolant supply tube at the turbocharger.
- Position the coolant supply tube aside.
7. NOTE: The heat insulating wrap is removed with the turbocharger bypass valve.
Disconnect the turbocharger bypass valve electrical connector. Disconnect the wastegate hose and the 2 bypass vacuum hoses.

9. Remove the turbocharger bracket bolt.
10. NOTE: Use a 3/8 inch Jiffy-tite quick disconnect tool, such as a Snap-on(R) LDTSP4 or equivalent, to disconnect the turbocharger coolant return tube.
Using a commercially available quick disconnect tool, disconnect the LH turbocharger coolant return tube at the turbocharger.
11. Remove the 3 turbocharger mounting bolts and the turbocharger.
- Discard the turbocharger exhaust manifold gasket.
12. Remove the turbocharger oil return tube assembly.
- Remove and discard the turbocharger oil return tube O-ring seal.
13. Loosen the 2 turbocharger bracket-to-cylinder block bolts.
14. NOTE: Use a 3/8 inch Jiffy-tite quick disconnect tool, such as a Snap-on(R) LDTSP4 or equivalent, to disconnect the turbocharger coolant tubes.
If necessary, remove the turbocharger coolant supply and the coolant outlet tubes.
15. If necessary, remove the 2 turbocharger exhaust flange stud bolts and the turbocharger exhaust flange.
- Discard the 2 turbocharger exhaust flange stud bolts and the turbocharger exhaust flange gasket.
Installation
1. NOTE: Apply high temperature nickel anti-seize lubricant to the turbocharger exhaust flange stud bolt threads prior to installation of the turbocharger exhaust flange.
