WARNING:
Do not remove the radiator cap when the engine is hot. Serious burns could occur from high-pressure
engine coolant escaping from the radiator. Wrap a th ick cloth around the cap. Slowly push down and
turn it a quarter turn to allow built-up pressure to escape. Carefully remove the cap by pushing it down
and turning it all the way.
CAUTION:
• When removing water pump assembly, be car eful not to get coolant on drive belt.
• Water pump cannot be disassembled and must be replaced as a unit.
• After installing the water pump, connect hose and clamp securely, then check for leaks. Repair as
necessary.
NOTE:
When removing components such as hoses, tubes/lines, etc. , cap or plug openings to prevent fluid from spill-
ing.
REMOVAL
1. Disconnect the negative battery terminal. Refer to PG-73, "Removal and Installation (Battery)".
2. Remove the core support cover clips (A), then remove the core support cover (1).
3. Remove front air duct. Refer to EM-84, "Removal and Installation"

PRECAUTIONS
Precaution for Supplemental Restraint Syst
em (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951635
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the SR and SB section of
this Service Manual.
WARNING:
• To avoid rendering the SRS inopera tive, 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 performed by
an authorized NISS AN/INFINITI dealer.
• Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintent ional activation of the system. For re moval of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipmen t on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harn esses can be identified by yellow and/or orange harnesses or har-
ness connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or electri c 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 three minutes before performing any service.
Precautions For Harness RepairINFOID:0000000009464647
ITS communication uses a twisted pair line. Be careful when repairing it.
• Solder the repaired area and wrap tape around the soldered area.
NOTE:
A fray of twisted lines must be within 110 mm (4.33 in).
• Bypass connection is never allowed at the repaired area. NOTE:
Bypass connection may cause ITS communication error. The
spliced wire becomes separated and the characteristics of twisted
line are lost.

DIAGNOSIS SYSTEM (ITS CONTROL UNIT)
DIAGNOSIS SYSTEM (ITS CONTROL UNIT)
CONSULT Function (AVM)INFOID:0000000009464652
CAUTION:
After disconnecting the CONSULT vehicle interface (VI) from the data link connector, the ignition must
be cycled OFF → ON (for at least 5 seconds) → OFF. If this step is not performed, the BCM may not go
to ”sleep mode”, potentially causing a di scharged battery and no-start condition.
APPLICATION ITEMS
CONSULT performs the following functions via CAN communication using ITS control unit.
SELF DIAGNOSTIC RESULT

[LHD/RHD] Indicates the steering position (LHD or RHD)
REAR CAMERA IMAGE SIGNAL
[OK/Not] Indicates the status of the rear camera image as read from ITS control unit through dedicated
ITS communication lines
WASH SW
[ON/OFF] Indicates the state of the wash switch indicator output
R-CAMERA COMM STATUS
[OK/Not] Indicates the status of the rear camera communication status as read from ITS control unit
through dedicated ITS communication lines
R-CAMERA COMM LINE
[OK/Not] Indicates the condition of the rear camera communication line whether transmitting properly
through dedicated ITS communication lines
