12. Remove idler pulley and bracket. Refer to EM-173, "
TIMING CHAIN" .
13. Remove timing chain tensioner (primary) as follows:
a. Remove lower mounting bolt.
b. Loosen upper mounting bolt slowly, and then turn timing chain
tensioner (primary) on the mounting bolt so that plunger is fully
expanded.
NOTE:
Even if plunger is fully expanded, it is not dropped from the body
of timing chain tensioner (primary).
c. Remove upper mounting bolt, and then remove timing chain ten-
sioner (primary).
CAUTION:
Be careful not to drop mounting bolts inside timing chain
case.
14. Remove water pump as follows:
a. Remove three water pump mounting bolts. Secure a gap
between water pump gear and timing chain, by turning crank-
shaft pulley counterclockwise until timing chain looseness on
water pump sprocket becomes maximum.
b. Screw M8 bolts [pitch: 1.25 mm (0.049 in) length: Approx. 50
mm (1.97 in)] into water pumps upper and lower mounting bolt
holes until they reach timing chain case. Then, alternately
tighten each bolt for a half turn, and pull out water pump.
CAUTION:
Pull straight out while preventing vane from contacting
socket in installation area.
Remove water pump without causing sprocket to contact
timing chain.
c. Remove M8 bolts and O-rings from water pump.
CAUTION:
Do not disassemble water pump.
INSPECTION AFTER REMOVAL
Check for badly rusted or corroded water pump body assembly.

mary).
f. Pull out stopper pin after installing, and then release plunger.
g. Make sure again that timing chain and water pump sprocket are
engaged.
4. Install chain tensioner cover and water pump cover as follows:
a. Before installing, remove all traces of old liquid gasket from mat-
ing surface of water pump cover and chain tensioner cover
using scraper. Also remove traces of old liquid gasket from the
mating surface of front timing chain case.
b. Apply a continuous bead of liquid gasket with tube presser [SST:
WS39930000] to mating surface of chain tensioner cover and
water pump cover.
Use Genuine Liquid Gasket or equivalent.
CAUTION:
Attaching should be done within 5 minutes after coating.
c. Tighten mounting bolts.
5. Install water drain plug (front) on water pump side of cylinder block.
Apply liquid gasket to the thread of water drain plug (front).
Use Genuine Liquid Gasket or equivalent.
6. Install in the reverse order of removal in this step.
NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal/installation, slack in guide may gen-
erate a pounding noise during and just after engine start. However, this does not indicate an unusualness.
Noise will stop after hydraulic pressure rises.
INSPECTION AFTER INSTALLATION
Check for leaks of engine coolant using radiator cap tester adapter [SST: EG17650301] and radiator cap
tester (commercial service tool). Refer to CO-34, "
LEAK CHECK" .
Start and warm up engine. Visually check if there is no leaks of engine coolant.

PRECAUTIONS
PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
BCS001NA
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the SRS and SB section of
this Service Manual.
WARNING:
To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be per-
formed by an authorized NISSAN/INFINITI dealer.
Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
Precautions Necessary for Steering Wheel Rotation After Battery DisconnectBCS001NB
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
Removal and Installation Procedure for CVT Unit ConnectorBCS001FS
REMOVAL
Rotate bayonet ring counterclockwise, pull out CVT unit harness
connector upward and remove it.
INSTALLATION
1. Align ∆ marking on CVT unit harness connector terminal body
with
❏ marking on bayonet ring, insert CVT unit harness con-
nector, and then rotate bayonet ring clockwise.
2. Rotate bayonet ring clockwise until ∆ marking on CVT unit har-
ness connector terminal body is aligned with the slit on bayonet
ring as shown in the figure (correctly fitting condition), install
