Separation Work
1. Install engine slingers into front of right bank cylinder head and
rear of left bank cylinder head.
2. Remove power steering oil pump from engine side. Refer to PS-
31, "POWER STEERING OIL PUMP" .
3. Remove engine mounting insulator under side nut with power
tool.
4. Lift with hoist and separate engine and transmission assembly
from suspension member.
CAUTION:

Before and during this lifting, always check if any harnesses are left connected.

Avoid damage to and oil/grease smearing or spills onto engine mounting insulator.
5. Remove alternator. Refer to SC-23, "
CHARGING SYSTEM" .
6. Remove starter motor. Refer to SC-10, "
STARTING SYSTEM" .
7. Separate engine from transmission assembly. Refer to AT- 2 6 6 , "
TRANSMISSION ASSEMBLY" .
8. Remove engine mounting insulator and bracket with power tool.
INSTALLATION
Note to the following, and install in the reverse order of removal.

For a location with a positioning pin, insert it securely into hole of
mating part.

For a part with a specified installation orientation, refer to com-
ponent figure in EM-110, "
2WD MODEL" .

When installing engine mounting bracket on cylinder block,
tighten two upper bolts (shown as A in figure) first. Then tighten
two lower bolts (shown as B in figure). (LH and RH sides)

Tighten rear member mounting bolts in numerical order shown
in figure.
INSPECTION AFTER INSTALLATION

Before starting engine, check the levels of engine coolant, engine oil and working fluid. If less than
required quantity, fill to the specified level.

Use procedure below to check for fuel leakage.
–Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel
leakage at connection points.
–Start engine. With engine speed increased, check again for fuel leakage at connection points.

Run engine to check for unusual noise and vibration.

Warm up engine thoroughly to make sure there is no leakage of engine coolant, engine oil, working fluid,
fuel and exhaust gas.Slinger bolts:

Precautions Necessary for Steering Wheel Rotation After Battery DisconnectABS00DAO
NOTE:

This Procedure is applied only to models with Intelligent 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-II 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 power 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-II.
Precautions for Drain Engine CoolantABS006HV
Drain engine coolant when engine is cooled.
Precautions for Disconnecting Fuel PipingABS006HW

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.
Precautions for Removal and DisassemblyABS006HX

When instructed to use special service tools, use specified tools. Always be careful to work safely, avoid
forceful or uninstructed operations.

Exercise maximum care to avoid damage to mating or sliding surfaces.

Cover openings of engine system with tape or the equivalent, if necessary, to seal out foreign materials.

Mark and arrange disassembly parts in an organized way for easy troubleshooting and assembly.

When loosening nuts and bolts, as a basic rule, start 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.
Precautions for Inspection, Repair and ReplacementABS006HY
Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and
replace if necessary.
Precautions for Assembly and InstallationABS006HZ

Use torque wrench to tighten bolts or nuts to specification.

General PrecautionsAAS000EY

Do not operate the engine for an extended period of time without
proper exhaust ventilation.
Keep the work area well ventilated and free of any inflammable
materials. Special care should be taken when handling any
inflammable or poisonous materials, such as gasoline, refriger-
ant gas, etc. When working in a pit or other enclosed area, be
sure to properly ventilate the area before working with hazard-
ous materials.
Do not smoke while working on the vehicle.

Before jacking up the vehicle, apply wheel chocks or other tire
blocks to the wheels to prevent the vehicle from moving. After
jacking up the vehicle, support the vehicle weight with safety
stands at the points designated for proper lifting before working
on the vehicle.
These operations should be done on a level surface.

When removing a heavy component such as the engine or tran-
saxle/transmission, be careful not to lose your balance and drop
them. Also, do not allow them to strike adjacent parts, especially
the brake tubes and master cylinder.
