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.

WATER PUMP
20. Remove water pump:
a. Screw M8 bolts approximately 50 mm (1.97 in) into water pump upper and lower bolt holes until they reach the timing chain case
[M8 bolt pitch 1.25 mm (0.49 in) length].
CAUTION:
• Place a suitable shop cloth below the water pump hous-
ing to prevent any co olant from dripping into the timing
chain case.
• Pull water pump straight out while preventing vane from
contacting socket in installation area.
• Remove water pump without causing sprocket to contact
timing chain.
b. Remove M8 bolts and O-rings from water pump. CAUTION:
Do not reuse O-rings.
INSPECTION AFTER REMOVAL
• Visually check for significant dirt or rust on the water pump body and vane.
• Check that the vane shaft turns smoothly by hand and is not
excessively loose.
• Replace the water pump assembly if the water pump does not per- form properly.
INSTALLATION
1. Install new O-rings on water pump (1).
CAUTION:
Do not reuse O-rings.
a. Apply engine oil to the O-rings (2,3) as shown.
b. Locate the O-ring (2) with white paint mark (A) to engine front side.
2. Hold timing chain to the side ( ) and install the water pump ().
CAUTION:
Do not allow the O-rings to be damaged by the cylinder
block when installing the water pump.
• Check that timing chain and water pump sprocket are
engaged.
• Tighten water pump bolts alternately and evenly to specifica- tion.
3. Remove dust and foreign material completely from installation area of timing chain tensioner and rear tim- ing chain case.

4. Turn the crankshaft pulley approximately 20
° clockwise so that
the timing chain on the timing chain tensioner side is loose.
5. Apply engine oil to the oil feed hole and timing chain tensioner and install the timing chain tensioner.
6. Remove the stopper pin (A).
7. Install valve timing control cover (bank 1) and water pump cover.
a. Before installing, remove all traces of liquid gasket from mating surface of water pump cover and IVT cover using a scraper.
Also remove traces of liquid gasket from the mating surface of the front cover.
b. Apply a continuous bead of liquid gasket to mating surface of IVT cover and water pump cover. Use Gen-
uine RTV Silicone Sealant or equivalent. Refer to GI-21, "Recommended Chemical Products and
Sealants".
CAUTION:
• Installation should be done within 5 minutes afte r applying liquid gasket.
• Do not fill the engine with oil for at least 30 minutes after the co mponents are installed to allow
the sealant to cure.
8. Install water drain plug (A) and copper sealing washer (B). CAUTION:
Do not reuse copper sealing washers.
9. Installation of remaining components is in the reverse order of removal. • After installation, refill coolant and check for leaks. Refer to CO-36, "Changing Engine Coolant"
and CO-
35, "System Inspection".
CAUTION:
Do not spill coolant in en gine compartment. Use a sh op cloth to absorb coolant.
• 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 the chai n tensioner. The engine may produce a rattling noise.
This indicates that air still remains in the chamber and is not a matter of concern.
INSPECTION AFTER INSTALLATION
• Before starting engine, check oil/fluid levels incl uding engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-11, "FOR USA AND CANADA : Fluids and Lubricants"
.

• Use procedure below to check for fuel leakage.
• Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leak- age at connection points.
• Start engine. With engine speed increased, che ck again for fuel leakage at connection points.
• Run engine to check for unusual noise and vibration. NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal and 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.
• Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gas, or any oils/fluids including engine oil and engine coolant.
• Bleed air from passages in lines and hoses, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to spec-
ified level, if necessary.

the reference value.
• After checking the full-open lift amount, lower the water tempera-
ture and check the valve closing temperature.
• If valve setting at measured values are out of standard range, replace thermostat.
INSTALLATION
Installation is in the reverse order of removal.
• Install thermostat with jiggle valve facing upward.
• After installation refill engine coolant and check for leaks. Refer to
CO-36, "Changing Engine Coolant"
and CO-35, "System Inspec-
tion".

Precaution for Supplemental Restraint Syst
em (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951640
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.
Precaution for WorkINFOID:0000000009464716
• When removing or disassembling each component, be careful not to damage or deform it. If a component may be subject to interference, be sure to protect it with a shop cloth.
• When removing (disengaging) components with a screwdriver or similar tool, be sure to wrap the component with a shop cloth or vinyl tape to protect it.
• Protect the removed parts with a s hop cloth and prevent them from being dropped.
• Replace a deformed or damaged clip.
• If a part is specified as a non-reusable part, always replace it with a new one.
• Be sure to tighten bolts and nuts securely to the specified torque.
• After installation is complete, be sure to check that each part works properly.
• Follow the steps below to clean components:
- Water soluble dirt:
• Dip a soft cloth into lukewarm water, wring the water out of the cloth and wipe the dirty area.
• Then rub with a soft, dry cloth.
- Oily dirt:
• Dip a soft cloth into lukewarm water with mild detergent (concentration: within 2 to 3%) and wipe the dirty area.
• Then dip a cloth into fresh water, wring the water out of the cloth and wipe the detergent off.
• Then rub with a soft, dry cloth.
- Do not use organic solvent such as thinner, benzene, alcohol or gasoline.
- For genuine leather seats, use a genuine leather seat cleaner.
