WARNING:
 Situate the vehicle on a flat and solid surface.
 Place chocks at front and back of rear wheels.
 For engines not equipped with engi
ne slingers, attach proper slingers and bolts described in PARTS
CATALOG.
CAUTION:
 Always be careful to work safely, avoid forceful or uninstructed operations.
 Do not start working until exhaust system and engine coolant are cool enough.
 If items or work required are not covered by th e engine section, refer to the applicable sections.
 Always use the support poin t specified for lifting.
 Use either 2-pole lift type or separate type lift as best you can. If board-on type is used for unavoid-
able reasons, support at rear axle jacking point with transmission jack or similar tool before starting
work, in preparation for the backward shift of center of gravity.
 For supporting points fo r lifting and jacking point at rear axle, refer to GI-37, "
Garage Jack and
Safety Stand".

, the transfer assembly and the front final drive assem-
bly with front suspension member downward. Then separa te the engine, the transmission assembly, the trans-
fer and the front final drive assembly.
Preparation
1. Release fuel pressure. Refer to EC-87, "Fuel Pressure Check".
2. Drain engine coolant from radiator. Refer to CO-10, "
Changing Engine Coolant".
CAUTION:
 Perform this step when engine is cold.
 Do not spill engine coolant on drive belts.
3. Disconnect both battery terminals. Refer to SC-4, "
How to Handle Battery".

9. Remove reservoir tank of power steering oil pump and piping from vehicle, and temporarily secure them
on engine. Refer to PS-27, "
On-Vehicle Inspection and Service".
CAUTION:
When temporarily securing, keep the reservo ir tank upright to avoid a fluid leak.

PRECAUTIONS
Precaution Necessary for Steering W
heel Rotation After Battery Disconnect
INFOID:0000000001524895
NOTE:
 This Procedure is applied only to models with In telligent Key system and NVIS/IVIS (NISSAN/INFINITI
VEHICLE IMMOBILIZER SYSTEM - NATS).
 Remove and install all control units after disconnecting both battery cables with the ignition knob in the ″LOCK ″ position.
 Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work.
If DTC is detected, perform trouble diagnosis according to self-diagnostic results.
For models equipped with the Intelligent Key system and NVIS /IVIS, an electrically controlled steering lock
mechanism is adopted on the key cylinder.
For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and
steering wheel rotation will become impossible.
If steering wheel rotation is required when battery pow er is interrupted, follow the procedure below before
starting the repair operation.
OPERATION PROCEDURE
1. Connect both battery cables. NOTE:
Supply power using jumper cables if battery is discharged.
2. Use the Intelligent Key or mechanical key to turn the ignition switch to the ″ACC ″ position. At this time, the
steering lock will be released.
3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be
rotated.
4. Perform the necessary repair operation.
5. When the repair work is completed, return the ignition switch to the ″LOCK ″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of all control units using CONSULT-III.
Precaution for Drain Engine Coolant and Engine OilINFOID:0000000001325752
Drain engine coolant and engine oil when engine is cooled.
Precaution for Disconnecting Fuel PipingINFOID:0000000001325753
 Before starting work, make sure no fire or spark producing items are in the work area.
 Release fuel pressure before disconnecting and disassembly.
 After disconnecting pipes, plug openings to stop fuel leakage.
Precaution for Removal and DisassemblyINFOID:0000000001325754
 When instructed to use SST, use specified tools. Always be careful to work safely, avoid forceful or unin-
structed operations.
 Exercise maximum care to avoid damage to mating or sliding surfaces.
 Cover openings of engine system with tape or the equival ent, if necessary, to seal out foreign materials.
 Mark and arrange disassembly parts in an organi zed way for easy troubleshooting and assembly.
 When loosening nuts and bolts, as a basic rule, star t with the one furthest outside, then the one diagonally
opposite, and so on. If the order of loosening is specified, do exactly as specified. Power tools may be used
where noted in the step.
Precaution for Inspection, Repair and ReplacementINFOID:0000000001325755
Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and
replace if necessary.
