Measure the outer diameter of piston pin with a micrometer (A).
Piston to Piston Pin Oil Clearance
(Piston to piston pin oil clearance) = (Piston pin hole diameter) – (Piston pin outer diameter)
If the calculated value is out of the standard, replace piston and piston pin assembly.
When replacing piston and piston pin assembly, refer to EM-129, "
Description".
NOTE:
Piston is available together with piston pin as assembly.
Piston pin (piston pin hole) grade is provided only for the parts installed at the plant. For service parts, no
piston pin grades can be selected. (Only “0” grade is available.)
PISTON RING SIDE CLEARANCE
Measure the side clearance of piston ring (1) and piston ring
groove with a feeler gauge (C).
If the measured value exceeds the limit, replace piston ring, and
measure again. If it still exceeds the limit, replace piston also.
PISTON RING END GAP
Check that the cylinder bore inner diameter is within the specification. Refer to EM-143, "CylinderBlock".
Lubricate with new engine oil to piston (1) and piston ring (2), and
then insert piston ring until middle of cylinder with piston, and mea-
sure the piston ring end gap with a feeler gauge (B).
If the measured value exceeds the limit, replace piston ring, and
measure again. If it still exceeds the limit, rebore cylinder and use
oversize piston and piston rings.

When (d) exceeds the limit (when it becomes thinner), replace
connecting rod bolt with new one.
DRIVE PLATE
Check drive plate and signal plate for deformation or damage.
CAUTION:
Never disassemble drive plate.
Never place drive plate with signal plate facing down.
When handling signal plate, take care not to damage or
scratch it.
Handle signal plate in a manner that prevents it from becom-
ing magnetized.
If anything is found, replace drive plate.
OIL JET (VQ35DE)
Check nozzle for deformation and damage.
Blow compressed air from nozzle, and check for clogs.
If it is not satisfied, clean or replace oil jet.

EXHAUST SYSTEM
Remove deposits from the sealing surface of each connection. Connect them securely to avoid
gases leakage.
When installing each mounting rubber, use silicon oil to avoid twisting.
Temporarily tighten mounting nuts and bolts. 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, front/rear
and right/left directions.
InspectionINFOID:0000000003793263
INSPECTION AFTER INSTALLATION
Check clearance between tail tube and rear bumper is even.
With engine running, check exhaust tube joints for gas leakage and unusual noises.
Check to ensure that mounting brackets and mounting rubbers are installed properly and free from undue
stress. Improper installation could result in excessive noise and vibration.

AUTO ACTIVE TEST
Description
In auto active test mode, the IPDM E/R sends a drive signal to the following systems to check their operation.
Oil pressure warning lamp
Front wiper (LO, HI)
Parking lamps
License plate lamps
Tail lamps
Front fog lamps
Headlamps (LO, HI)
A/C compressor (magnet clutch)

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000003813382
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 AIRBAG” and “SEAT BELT” 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 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 AIRBAG”.
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.
Precautions For Xenon Headlamp ServiceINFOID:0000000003773614
WARNING:
Comply with the following warnings to prevent any serious accident.
Disconnect the battery cable (negative terminal) or the power supply fuse before installing, remov-
ing, or touching the xenon headlamp (bulb included). The xenon headlamp contains high-voltage
generated parts.
Never work with wet hands.
Check the xenon headlamp ON-OFF status after assembling it to the vehicle. Never turn the xenon
headlamp ON in other conditions. Connect the power supply to the vehicle-side connector.
(Turning it ON outside the lamp case may cause fire or visual impairments.)
Never touch the bulb glass immediately after turning it OFF. It is extremely hot.
CAUTION:
Comply with the following cautions to prevent any error and malfunction.
Install the xenon bulb securely. (Insufficient bulb socket installation may melt the bulb, the connec-
tor, the housing, etc. by high-voltage leakage or corona discharge.)
Never perform HID circuit inspection with a tester.
Never touch the xenon bulb glass with hands. Never put oil and grease on it.
Dispose of the used xenon bulb after packing it in thick vinyl without breaking it.
Never wipe out dirt and contamination with organic solvent (thinner, gasoline, etc.).
