• Do not pull with lateral force applied. O-ring inside quick connector may be damaged.
• Prepare container and cloth beforehand as fuel will leak out.
• Avoid fire and sparks.
• Keep parts away from heat source. Especially, be careful when welding is performed around
them.
• Do not expose parts to battery electrolyte or other acids.
• Do not bend or twist connection between quick connector and fuel feed hose during installation/
removal.

Valve Clearance".
13. Installation of the remaining components is in the reverse order of removal.
INSPECTION AFTER INSTALLATION
The following are procedures for checking fluids leak, lubricates leak.
• Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to GI-42, "
Recommended Chemical Product and Sealant".
• 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, check 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/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, or any oil/fluids including engine oil and
engine coolant.
• Bleed air from lines and hoses of applicable lines, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the
specified level, if necessary.
Summary of the inspection items:
* Transmission/transaxle/CVT fluid, power steering fluid, brake fluid, etc.
Inspection of Camshaft Sprocket (INT) Oil Groove
CAUTION:
• Perform this inspection only when DTC P0011 is detected in self-diagnostic results of CONSULT-III
and it is directed according to inspection procedure of EC section. Refer to EC-46
.
• Check when engine is cold so as to prevent burns from the splashing engine oil.
1. Check engine oil level. Refer to LU-6, "
Inspection".
2. Perform the following procedure so as to prevent the engine from being unintentionally started while
checking.
a. Remove intake manifold. Refer to EM-18, "
Component".
b. Disconnect ignition coil and injector harness connectors.

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001830414
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 and SB section of this Service Man-
ual.
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 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 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 har-
ness connectors.

• Be sure to use genuine NISSAN exhaust system parts or equivalents which are specially designed
for heat resistance, corrosion resistance and shape.
• Perform the operation with the exhaust system fully cooled down because the system will be hot
just after the engine stops.
• Be careful not to cut your hand on heat insulator edge.
1. Disconnect harness connector of heated oxygen sensor 2.
• Using Tool, remove heated oxygen sensor 2.
CAUTION:
Be careful not to damage heated oxygen sensor 2.
a.2. Disconnect each joint and mounting rubber.
INSTALLATION
Installation is in the reverse order of removal.
CAUTION:
• Always replace exhaust gaskets and seal bearings with new ones when installing.
• Discard any heated oxygen sensor 2 which has been dropped from a height of more than 0.5 m (19.7
in) onto a hard surface such as a concrete floor; use a new one.
• Before installing a new heated oxygen sensor 2, clean exhaust system threads using the heated oxy-
gen sensor thread cleaner and apply anti-seize lubricant (commercial service tool).
• Do not over tighten heated oxygen sensor 2. Doing so may cause damage to the heated oxygen sen-
sor 2, resulting in the “MIL” coming on.
• Remove deposits from the sealing surface of each connection. Connect them securely to avoid
exhaust leakage.
• Temporarily tighten nuts on the exhaust manifold side and bolts on the vehicle side. Check each part
for unusual interference, and then tighten them to the specified torque.
• When installing each mounting rubber, avoid twisting or unusual extension in up/down and right/left
directions.
Exhaust Manifold to Exhaust Front Tube
1. Securely insert seal bearing (2) into exhaust manifold (1) side in
the direction shown.
• Exhaust front tube (5)
CAUTION:
Be careful not to damage seal bearing surface when install-
ing.
2. Install spring (3), tighten nut (4).
• Be careful that the stud bolt nut does not interfere with the
flanged area ( ).
• Make sure the spring (3) sits properly on the flange surface by
aligning it to the locator dimples.
Exhaust Front Tube to Center Muffler
1. Securely insert seal bearing (2) into exhaust front tube (1) side
in the direction shown.
• Center muffler (5)
CAUTION:
Be careful not to damage seal bearing surface when install-
ing.
2. With spring (3), tighten bolt (4).
• Be careful that the stud bolt does not interfere with the flanged
area ( ).
• Make sure the spring (3) sits properly on the flange surface by
aligning it to the locator dimples.
INSPECTION AFTER INSTALLATION
• With the engine running, check exhaust tube joints for exhaust leakage and unusual noise.
• Check to ensure that brackets and mounting rubbers are installed properly and free from undue stress.
Improper installation could result in excessive noise and vibration.Tool number : KV10114400 (J-38365)

Checking Fuel LineINFOID:0000000001703097
Inspect fuel lines, fuel filler cap and fuel tank for improper attach-
ment, leaks, cracks, damage, loose connections, chafing or deterio-
ration.
If necessary, repair or replace damaged parts.
General PrecautionINFOID:0000000001703098
WARNING:
When replacing fuel line parts, be sure to observe the following.
• Put a “CAUTION: FLAMMABLE” sign in the work area.
• Be sure to work in a well ventilated area and have a CO
2 fire extinguisher.
• Do not smoke while working on the fuel system. Keep open flames and sparks away from the work
area.
• Put drained fuel in an explosion-proof container and put the lid on securely. Keep the container in
safe area.
CAUTION:
• Use gasoline required by the regulations for octane number. Refer to GI-4, "
Precaution for Fuel
(Unleaded Regular Gasoline Recommended)".
• Before removing fuel line parts, perform the following procedures:
- Release fuel pressure from the fuel lines. Refer to EC-78, "
Fuel Pressure Check".
- Disconnect the battery ground cable.
• Always replace O-rings and clamps with new ones.
• Do not kink or twist tubes when they are being installed.
• Perform work on level surface.
• Do not tighten hose clamps excessively to avoid damaging hoses.
• After connecting fuel tube quick connectors, make sure quick connectors are secure.
Ensure that connector and resin tube do not contact any adjacent parts.
• After installing tubes, make sure there is no fuel leakage at connections in the following steps.
- Apply fuel pressure to fuel lines by turning ignition switch ON (without starting the engine). Then
check for fuel leaks at the fuel tube connections.
- Start engine and rev it up and check for fuel leaks at connections.
• Use only a genuine NISSAN fuel filler cap as a replacement. If an incorrect fuel filler cap is used, the
MIL may come on.
