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 (0.0492 in) length: approxi-
mately 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:
Never disassemble water pump.
INSTALLATION
CAUTION:
Do not reuse O-rings.
1.
Install new O-rings to water pump.
CAUTION:
Do not reuse O-rings.
• Apply engine oil and engine coolant to O-rings as shown in the
figure.
• Locate O-ring with white paint mark to engine front side.
2.
Install water pump.
CAUTION:
Never allow cylinder block to nip O-rings when installing
water pump.
• Check that timing chain and water pump sprocket are
engaged.
• Insert water pump by tightening mounting bolts alternately and

WATER PUMP
a.
Turn crankshaft pulley clockwise so that timing chain on the tim-
ing chain tensioner (primary) side is loose.
b.
Pull plunger stopper tab (A) up (or turn lever downward) so as to
remove plunger stopper tab from the ratchet of plunger (D).
NOTE:
Plunger stopper tab and lever (C) are synchronized.
c.
Push plunger into the inside of tensioner body.
d.
Hold plunger in the fully compressed position by engaging
plunger stopper tab with the tip of ratchet.
e.
To secure lever, insert stopper pin (E) through hole of lever into
tensioner body hole (B).
• The lever parts and the tab are synchronized. Therefore, the
plunger will be secured under this condition.
NOTE:
Figure shows the example of 1.2 mm (0.047 in) diameter thin screwdriver being used as the stopper pin.
f.
Install timing chain tensioner (primary).
• Remove dust and foreign material completely from backside of timing chain tensioner (primary) and
from installation area of rear timing chain case.
g.
Remove stopper pin (A).
h.
Check again that timing chain and water pump sprocket are engaged.
4.
Install valve timing control cover (bank 1) and water pump cover as follows:
a.
Before installing, remove all traces of old liquid gasket from mating surface of water pump 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 the tube presser
(commercial service tool) to mating surface of water pump cover
(1).
Use Genuine RTV Silicone Sealant or equivalent. Refer to
GI-22, "Recommended Chemical Products and Sealants"
.
CAUTION:
Attaching should be done within 5 minutes after coating.

• After starting engine, let idle for three minutes, then rev engine up to 3,000 rpm under no load to
purge air from the high-pressure chamber of chain tensioner. Engine may produce a rattling
noise. This indicates that air still remains in the chamber and is not a matter of concern.

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000008462886
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. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the “SRS AIR BAG” and “SEAT BELT” of this
Service Manual.
WARNING:
Always observe the following items for preventing accidental activation.
• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in
the event of a collision that would result in air bag inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.
• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see “SRS AIR BAG”.
• Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-
vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
Always observe the following items for preventing accidental activation.
• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the
ignition ON or engine running, never use air or electric power tools or strike near the sensor(s) with
a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing
serious injury.
• When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the
battery, and wait at least 3 minutes before performing any service.
Precaution for Battery Service
INFOID:0000000008462887
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.
Service Procedure Precautions for Models with a Pop-up Roll Bar
INFOID:0000000008462888
WARNING:
Always observe the following items for preventing accidental activation.
• Risk of passenger injury or death may increase if the pop-up roll bar does not deploy during a roll
over collision. In order to reduce the chance of an incident where the pop-up roll bar is inoperative,
all maintenance must be performed by a NISSAN or INFINITI dealer.
• Before removing and installing the pop-up roll bar component parts and harness, always turn the
ignition switch OFF, disconnect the battery negative terminal, and wait for 3 minutes or more. (The
purpose of this operation is to discharge electricity that is accumulated in the auxiliary power supply
circuit in the air bag diagnosis sensor unit.)
• When repairing, removing, and installing a pop-up roll bar, always refer to SRS AIR BAG and SRS
AIR BAG CONTROL warnings in the Service Manual.

System Description

OPERATION DESCRIPTION
• Turn rear window defogger switch ON while ignition switch is ON. Then multifunction switch (rear window
defogger switch) transmits rear window defogger switch signal to AV control unit via AV communication. AV
control unit transmits rear window defogger switch signal to BCM via CAN communication.
• BCM turns rear window defogger relay ON and transmits rear window defogger control signal to IPDM E/R
via CAN communication when rear window defogger switch signal is received.
• Door mirror defoggers are supplied with power and operate when rear window defogger relay turns ON.
• Rear window defogger relay sends power supply to soft top control unit.
• Soft top control unit detects roof state and controls rear window defogger operation.
• IPDM E/R transmits rear window defogger control signal to AV control unit via CAN communication.
• When receiving the signal, AV control unit indicates rear defogger ON on the display. At the same time, AV
control unit transmits rear window defogger feedback signal to multifunction switch (rear window defogger
switch) via AV communication and illuminates rear window defogger switch indicator.
TIMER FUNCTION
• BCM turns rear window defogger relay ON for approximately 15 minutes when rear window defogger switch
is turned ON. It makes rear window defogger and door mirror defoggers operate.
• Timer is canceled after pressing rear window defogger switch again during timer operation. Then BCM turns
rear window defogger relay OFF. The same operation also occurs during timer operation, if the ignition
switch is turned OFF.
