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 to EM-102, "

Precautions Necessary for Steering Wheel Rotation After Battery DisconnectABS00DB1
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 OilABS006HV
Drain engine coolant and engne oil 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 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 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.

1. Make sure that crankshaft key and dowel pin of each camshaft
are located as shown in the figure. (No. 1 cylinder at compres-
sion 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.
2. Install camshaft sprockets.
Install onto correct side by checking with identification mark
on surface.
Install camshaft sprocket (EXH) by selectively using the
groove of dowel pin according to the bank. (Common part
used for both banks.)
Lock the hexagonal part of camshaft in the same procedure
as for removal, and tighten mounting bolts.
3. Install crankshaft sprockets for both banks.
Install each crankshaft sprocket so that its flange side (the
larger diameter side without teeth) faces in the direction
shown in the figure.
NOTE:
The same parts are used but facing directions are different. Camshaft dowel pin
: At cylinder head upper face side in each bank
Crankshaft key : At cylinder head side of left bank

7. Install oil pump drive spacer as follows:
a. Insert oil pump drive spacer according to the directions of crank- shaft key and the two flat surfaces of oil pump inner rotor.
If the positional relationship does not allow the insertion,
rotate oil pump inner rotor with a finger to allow spacer.
b. After confirming that the position of each part is in correct condi- tion to allow for spacer, force fit spacer by lightly tapping with
plastic hammer until it contacts and does not go further.
8. Install front oil seal on front cover.
Apply new engine oil to both oil seal lip and dust seal lip.
Install it so that each seal lip is oriented as shown in the fig-
ure.
CAUTION:
Be careful not to scratch or make burrs on circumference
of oil seal.
Using front oil seal drift (commercial service tool), press fit
until the height of front oil seal is level with the mounting sur-
face.
Make sure the garter spring is in position and seal lips not
inverted.
9. Install chain tensioner cover to front cover.
Apply a continuous bead of liquid gasket with tube presser
[SST: WS39930000 ( — )] to front cover as shown in the
figure.
Use Genuine RTV Silicone Sealant or equivalent. Refer to
GI-48, "
RECOMMENDED CHEMICAL PRODUCTS AND
SEALANTS" .
10. Install front cover as follows:

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 bolt wrench (commercial service tool).
CAUTION:
If cylinder head bolts are re-used, check their outer diame-
ters before installation. Refer to EM-231, "
Cylinder Head
Bolts Outer Diameter" .
a. Apply new engine oil to threads and seating surface of cylinder head bolts.
b. Tighten all cylinder head bolts. 98.1 N·m (10 kg-m, 72 ft-lb).
c. Completely loosen all cylinder head bolts. CAUTION:
In step “c”, loosen cylinder head bolts in reverse order of that indicated in the figure.
d. Tighten all cylinder head bolts to 44.1 N·m (4.5 kg-m, 33 ft-lb).
e. Turn all cylinder head bolts 60 degrees clockwise. (Angle tight- ening)
CAUTION:
Check the tightening angle by using angle wrench (SST).
Avoid judgment by visual inspection without SST.
Check tightening angle indicated on angle wrench indicator
plate.
f. Turn all cylinder head bolts 60 degrees clockwise again. (Angle tightening)
4. Install in the reverse order of removal.
