TRUNK LID FINISHER

4. Remove trunk lid finisher upper mounting clips, and then pull out
trunk lid finisher upper toward rear of vehicle.
5. Disconnect request switch harness connector (only for models with intelligent key) after pulling out, then
remove trunk lid finisher upper.
6. Continuously, remove trunk lid finisher lower mounting clips the same as in step 4, and then remove trunk
lid finisher lower.
CAUTION:
After removal, visually inspect finisher, and if it is deformed, replace it with new molding.
INSTALLATION
Install in the reverse order of removal.
CAUTION:

Replace double-faced adhesive tape on back of finisher with a new tape if trunk lid finisher (lower)
is reused.

Remove double-faced adhesive tape remaining on body and back of finisher using double-faced
adhesive tape remover (SUMITOMO 3M Cleaner 30 or equivalent) when removing finisher (lower).

Install after cleaning adhesive parts of body side and back of finisher (lower).

Do not wash the vehicle within 24 hours after installing so as to keep adhesive.

Precautions Necessary for Steering Wheel Rotation After Battery DisconnectBBS005KH
NOTE:

This Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-THEFT
SYSTEM).

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 NATS, an electrically controlled steering lock mech-
anism 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 CoolantBBS005KI
Drain engine coolant when engine is cooled.
Precautions for Disconnecting Fuel PipingBBS005KJ

Before starting work, make sure no fire or spark producing items are in the work area.

Release fuel pressure before disassembly.

After disconnecting pipes, plug openings to stop fuel leakage.
Precautions for Removal and DisassemblyBBS005KK

When instructed to use special service tools, use the 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 re-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.
Precautions for Inspection, Repair and ReplacementBBS005KL
Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and
replace if necessary.
Precautions for Assembly and InstallationBBS005KM

Use torque wrench to tighten bolts or nuts to specification.

TIMING CHAIN

INSTALLATION
NOTE:
The figure shows the relationship between the mating mark on each
timing chain and that on the corresponding sprocket, with the com-
ponents installed.
1. Make sure that crankshaft key points straight up.
2. Tighten mounting bolts in numerical order as shown in the figure
with the following procedure to install balancer unit.
CAUTION:
If mounting bolts are re-used, check their outer diameter
before installation. Refer to EM-57, "
Balancer Unit Mounting
Bolt Outer Diameter" .
a. Apply new engine oil to threads and seat surfaces of mounting
bolts.
b. Tighten all bolts.
c. Turn all bolts 90 degrees clockwise (angle tightening).
CAUTION:
Check tightening angle with angle wrench (SST) or a pro-
tractor. Do not make judgment by visual check alone.
d. Completely loosen.
CAUTION:
In this step, loosen bolts in reverse order as shown in the
figure.
e. Tighten all bolts.
f. Turn them another 90 degrees clockwise (angle tightening).

the figure.
Use Genuine Liquid Gasket or equivalent.
d. Tighten mounting bolts in numerical order as shown in the fig-
ure.
e. Install intake valve timing control solenoid valves to intake valve timing control cover if removed.
f. Connect ground cables, and install harness clip.
10. Insert crankshaft pulley by aligning with crankshaft key.

When inserting crankshaft pulley with plastic hammer, tap on its center portion (not circumference).
CAUTION:
Install protecting front oil seal lip section from any damage.
11. Tighten crankshaft pulley bolt with the following procedure.

Secure crankshaft pulley with pulley holder [SST: KV10109300], and tighten crankshaft pulley bolt.
a. Apply new engine oil to thread and seat surfaces of crankshaft pulley bolt.
b. Tighten crankshaft pulley bolt.
c. Put a paint mark on crankshaft pulley, mating with any one of six
easy to recognize angle marks on bolt flange.
d. Turn another 60 degrees clockwise (angle tightening).

Check the tightening angle with movement of one angle mark.
12. Install all removed parts in the reverse order of removal.
NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal/installation, slack in the guide may
generate a pounding noise during and just after engine start. However, this is normal. Noise will stop after
hydraulic pressure rises.
