PRECAUTIONSPFP:00001
Precautions for Procedures without Cowl Top CoverNBS003FC
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Precautions for Battery ServiceNBS003FD
Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interfer-
ence between the window edge and the vehicle when the door is opened/closed. During normal operation, the
window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic
window function will not work with the battery disconnected.
Precautions for Drain Engine Coolant and Engine OilNBS00002
Drain engine coolant and engine oil when engine is cooled.
Precautions for Disconnecting Fuel PipingNBS00003
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 DisassemblyNBS00004
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 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 bolts and nuts, 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 in the step.
Precautions for Inspection, Repair and ReplacementNBS00005
Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and
replace if necessary.
Precautions for Assembly and InstallationNBS00006
Use torque wrench to tighten bolts or nuts to specification.
When tightening bolts and nuts, as a basic rule, equally tighten in several different steps starting with the
ones in center, then ones on inside and outside diagonally in this order. If the order of tightening is speci-
fied, do exactly as specified.
Replace with new gasket, packing, oil seal or O-ring.
Dowel pins are used for several parts alignment. When replacing and reassembling with dowel pins, make
sure that dowel pins are installed in the original portion.
Thoroughly wash, clean, and air-blow each part. Carefully check engine oil or engine coolant passages for
any restriction and blockage.
Avoid damaging sliding or mating surfaces. Completely remove foreign materials such as cloth lint or dust.
Before assembly, oil sliding surfaces well.
Release air within route when refilling after draining engine coolant.

PRECAUTIONS
Revision: 2006 November2007 350Z
After repairing, start engine and increase engine speed to check engine coolant, fuel, engine oil, and
exhaust gases for leakage.
Parts Requiring Angle TighteningNBS00007
Use angle wrench [SST: KV10112100 (BT8653-A)] for the final tightening of the following engine parts:
–Cylinder head bolts
–Lower cylinder block bolts
–Connecting rod cap bolts
Do not use a torque value for final tightening.
The torque value for these parts are for a preliminary step.
Ensure thread and seat surfaces are clean and coated with engine oil.
Precautions for Liquid GasketNBS00008
REMOVAL OF LIQUID GASKET SEALING
After removing mounting bolts and nuts, separate the mating
surface using seal cutter (SST) and remove old liquid gasket
sealing.
CAUTION:
Be careful not to damage the mating surfaces.
Tap seal cutter to insert it, and then slide it by tapping on the
side as shown in the figure.
In areas where seal cutter (SST) is difficult to use, use plastic
hammer to lightly tap the parts, to remove it.
CAUTION:
If for some unavoidable reason tool such as screwdriver is
used, be careful not to damage the mating surfaces.
LIQUID GASKET APPLICATION PROCEDURE
1. Using scraper, remove old liquid gasket adhering to the gasket
application surface and the mating surface.
Remove liquid gasket completely from the groove of the gas-
ket application surface, mounting bolts, and bolt holes.
2. Wipe the liquid gasket application surface and the mating sur-
face with white gasoline (lighting and heating use) to remove
adhering moisture, grease and foreign materials.
3. Attach liquid gasket tube to tube presser [SST: WS39930000
(—)].
Use Genuine RTV Silicone Sealant or equivalent. Refer to
GI-45, "
RECOMMENDED CHEMICAL PRODUCTS AND
SEALANTS" .
4. Apply liquid gasket without breaks to the specified location with
the specified dimensions.
If there is a groove for liquid gasket application, apply liquid
gasket to the groove.

c. Shaft is engaged with intake side camshaft sprocket center hole
on inside. Pull straight out so as not to tilt until the joint is disen-
gaged.
The mating surface of magnet retarder may be fitted with the
exhaust side camshaft sprocket via the engine oil. Open valve
timing control cover carefully.
If the mating surface of magnet retarder is fitted with the cam-
shaft sprocket, open the cover within the range that the load is
not applied to the harness. And then, remove it so as to pre-
vent magnet retarder from dropping.
CAUTION:
Be careful not to damage magnet retarder.
When carrying valve timing control cover, face the magnet retarder side up to prevent the cover
from falling from magnet retarder.
Do not remove magnet retarder from valve timing control cover. (Disassembly prohibited parts)
18. Remove rocker covers (right and left banks). Refer to EM-40, "
ROCKER COVER" .
NOTE:
When only timing chain (primary) is removed, rocker cover does not need to be removed.
19. Obtain No. 1 cylinder at TDC of its compression stroke as follows:
NOTE:
When timing chain is not removed/installed, this step is not required.
a. Rotate crankshaft pulley clockwise to align timing mark (grooved
line without color) with timing indicator.
b. Make sure that intake and exhaust cam noses on No. 1 cylinder
(engine front side of right bank) are located as shown in the fig-
ure.
If not, turn crankshaft one revolution (360 degrees) and align
as shown in the figure.
NOTE:
When only timing chain (primary) is removed, rocker cover does
not need to be removed. To make sure that No. 1 cylinder is at
its compression TDC, remove front timing chain case first. Then
check mating marks on camshaft sprockets. Refer to EM-60,
"INSTALLATION" .
20. Remove crankshaft pulley as follows:
a. Remove rear cover plate and set ring gear stopper [SST:
KV10118600 (J-48641)] (A) as shown in the figure.

c. Install valve timing control cover with new gasket to front timing
chain case.
CAUTION:
Do not face the magnet retarder side down to prevent
magnet retarder from dropping.
Check the mating surface of magnet retarder and the
drum of exhaust side camshaft sprocket for foreign mate-
rials.
Align the center of both shaft holes of the shaft and the
intake side camshaft sprocket, and then insert them.
Be careful not to drop the seal ring from the shaft groove.
When setting the valve timing control cover in position by hand, if valve timing control cover is
not contacting with the front timing chain case, the dowel pin of magnet retarder may not be
aligned with the dowel pin holes of cover. In this case, return to step “b”.
d. Tighten mounting bolts in numerical order as shown in the fig-
ure.
CAUTION:
Completely tighten the mounting bolts with the seat surface
of valve timing control cover contacting with front timing
chain case.
After all bolt are tightened, tighten No.1 bolt to the specified torque again.
8. Install crankshaft pulley as follows:
a. Fix crankshaft using ring gear stopper [SST: KV10118600 (J-48641)].
b. Install crankshaft pulley, taking care not to damage front oil seal.
When press-fitting crankshaft pulley with plastic hammer, tap on its center portion (not circumference).
c. Tighten crankshaft pulley bolt.
d. Place a paint mark (A) on crankshaft pulley (2) aligning with the
angle mark (C) on crankshaft pulley bolt (1). Tighten the bolt 90
degrees (one marks) (b).
9. Rotate crankshaft pulley in normal direction (clockwise when viewed from front) to confirm it turns
smoothly.
10. Install in the reverse order of removal after this step.
