Precautions for Procedures without Cowl Top CoverNBS004MF
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Precautions Necessary for Steering Wheel Rotation After Battery DisconnectNBS005RR
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 Coolant and Engine OilNBS004MH
Drain engine coolant and engine oil when the engine is cooled.
Precautions for Disconnecting Fuel PipingNBS004MI
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 DisassemblyNBS004MJ
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.

g. After installing rear timing chain case, check the surface height
difference between the following parts on the oil pan (upper)
mounting surface.
If not within the standard, repeat the installation procedure.
3. Install water pump with new O-rings. Refer to CO-24, "
WATER PUMP" .
4. Make sure that dowel pin hole, dowel pin and crankshaft key are
located as shown in the figure. (No. 1 cylinder at compression
TDC)
NOTE:
Though camshaft does not stop at the position as shown in the
figure, for the placement of cam nose, it is generally accepted
camshaft is placed for the same direction of the figure.
CAUTION:
Hole on small dia. side must be used for intake side dowel pin hole. Do not misidentify (ignore big
dia. side).
5. Install timing chains (secondary) and camshaft sprockets as follows:
CAUTION:
Mating marks between timing chain and sprockets slip easily. Confirm all mating mark positions
repeatedly during the installation process.
a. Push plunger of timing chain tensioner (secondary) and keep it
pressed in with a stopper pin.Standard
Rear timing chain case to cylinder block:
–0.24 to 0.14 mm (–0.0094 to 0.0055 in)

Cylinder Head Distortion
NOTE:
When performing this inspection, cylinder block distortion should be also checking. Refer to EM-143, "
CYLIN-
DER BLOCK DISTORTION" .
1. Using a scraper, wipe off oil, scale, gasket, sealant and carbon deposits from surface of cylinder head.
CAUTION:
Do not allow gasket fragments to enter engine oil or engine coolant passages.
2. At each of several locations on bottom surface of cylinder head,
measure the distortion in six directions.
If it exceeds the limit, replace cylinder head.
INSTALLATION
1. Install new cylinder head gaskets.
2. Turn crankshaft until No. 1 piston is set at TDC.
Crankshaft key should line up with the right bank cylinder cen-
ter line as shown in the figure.
3. Install cylinder head follow the steps below to tighten cylinder
head bolts in numerical order as shown in the figure with cylin-
der head bolts wrench (commercial service tool).
CAUTION:
If cylinder head bolts re-used, check their outer diameters
before installation. Refer toEM-103, "
Cylinder Head Bolts
Outer Diameter" .
a. Apply new engine oil to threads and seat surfaces of cylinder
head bolts.
b. Tighten all cylinder head bolts.
c. Completely loosen all cylinder head bolts.
CAUTION:
In step “c”, loosen bolts in reverse order of that indicated in
the figure.
d. Tighten all cylinder head bolts.Limit : 0.1 mm (0.004 in)

DISASSEMBLY
NOTE:
Explained here is how to disassemble with engine stand supporting transmission surface. When using differ-
ent type of engine stand, note with difference in steps and etc.
1. Remove the engine assembly from the vehicle. Refer to EM-29, "
Removal and Installation (2WD Models)"
or EM-36, "Removal and Installation (AWD Models)" .
2. Remove the parts that may restrict installation of engine to widely use engine stand.
