Removal and Installation: Removal

WARNING: This page is about a different car, the 2018 Nissan Titan XD. However, it is still accessible from the selected car via links, so may be relevant.

WARNING:

To avoid the risk of personal injury:
- Be careful not to burn yourself, as engine oil may be hot.
- Prolonged and repeated contact with used engine oil may cause skin cancer; try to avoid direct skin contact with used engine oil. If skin contact is made, wash thoroughly with soap or hand cleaner as soon as possible. Avoid inhalation of vapors, ingestion, and prolonged contact with used engine oil.
- If not reused, dispose of in accordance with local environmental regulations.

CAUTION: To avoid possible engine and system damage or performance issues:

Brush away all dirt and debris from the area prior to opening any fuel, air intake, exhaust, cooling, aftertreatment or other engine system.
To avoid contamination, any open engine system ports must be closed immediately with clean care caps or an appropriate covering.
Do not allow any debris to fall into the engine.
Do not allow any chemical cleaners to enter the engine or any open systems during the cleaning process.

Disconnect the battery or batteries. Refer to Battery Disconnect .
Remove the intake manifold. Refer to Removal and Installation .
Remove the nuts and studs that connect the exhaust manifold collector pipe to the turbocharger. Refer to Exploded View .
Remove the charge-air cooler outlet tube from the turbocharger compressor outlet connection. Refer to Exploded View .
Disconnect the vacuum hose (2) from the turbocharger compressor bypass valve actuator (1).

Disconnect the downpipe from the turbocharger. Refer to Exploded View .
Disconnect the harness connector from the turbocharger speed sensor and from the low pressure turbocharger boost pressure sensor.
Remove the bolt (A) for the turbocharger oil drain line (1) on the cylinder block.

CAUTION: Do not remove the oil supply fitting from the block unless damaged. If fitting is required to be removed, vacuum all loose dirt from around the area of the oil supply fitting to avoid oil system contamination and potential engine damage.

Remove bolts (A) from the turbocharger (1) and remove the turbocharger from the engine (2).

WARNING: To avoid the risk of personal injury, use lifting equipment or acquire assistance when lifting components or assemblies that weight more than 23 kg (50 lbs).

CAUTION:

To avoid possible damage to various turbocharger components, use caution when routing the lifting device so that it does not contact any sensitive turbocharger components such as sensors, linkages or tubing.
To avoid possible damage to the turbocharger or its components, place the turbocharger on a clean flat surface. Ensure the turbocharger assembly rests on the housing and not on linkages or sensors.

NOTE:

While lifting slowly, ensure the high pressure turbocharger oil drain line disconnects from the cylinder block. A flat, blunt object may be used to help release the line.

When removing the turbocharger, cap all open air handling ports with Tool.

Tool	: -- - (J-54423)

While lifting slowly, make sure the high-pressure turbocharger oil drain line disconnects from the cylinder block. Using a suitable tool may help to release the line.
Make sure not to damage the low pressure turbocharger boost pressure sensor tube or the turbocharger compressor bypass valve, actuator, or linkage, while using a strap to remove the turbocharger.
If the full diagnostic procedures have already found that the turbocharger assembly must be replaced, disassembly steps are not needed. Replace the turbocharger assembly.
