• When removing or installing various parts, place a cloth or padding on the vehicle body to prevent scratches.
• Handle trim, molding, instruments, grille, etc. carefully during removing or installing. Be careful not to soil or
damage them.
• Apply sealing compound where necessary when installing parts.
• When applying sealing compound, be careful that the sealing compound does not protrude from parts.
• When replacing any metal parts (for example body outer panel, members, etc.), be sure to take rust preven-
tion measures.
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000003533115
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.

1. Cylinder bore size is determined by adding piston-to-bore clearance to piston diameter “A”.
2. Install main bearing caps, and tighten them to the specified torque. Otherwise, cylinder bores may be dis-
torted in final assembly.
3. Cut the cylinder bores.
NOTE:
• When any cylinder needs boring, all other cylinders must also be bored.
• Do not cut too much out of cylinder bore at one time. Cut only 0.05 mm (0.0020 in) or so in diameter at a
time.
4. Hone cylinders to obtain the specified piston-to-bore clearance.
5. Measure finished cylinder bore for out-of-round and taper.
NOTE:
Measurement should be done after cylinder bore cools down.
CRANKSHAFT JOURNAL DIAMETER
• Measure diameter of crankshaft journals.
• If measurement is out of standard, measure the main bearing oil clearance. Then use the undersize bearing.
CRANKSHAFT PIN DIAMETER
• Measure diameter of crankshaft pin using suitable tool.
• If measurement is out of standard, measure connecting rod bear-
ing oil clearance. Then use undersize bearing.
OUT-OF-ROUND AND TAPER OF CRANKSHAFT
• Measure dimensions at four different points as shown on each
journal and pin.
• Out-of-roundness is indicated by the difference in dimension
between ″X″ and ″Y″ at ″A″ and ″B″.
• Taper is indicated by the difference in dimension between ″A″ and
″B″ at ″X″ and ″Y″.
• If measured value exceeds the standard, correct or replace crankshaft.
• If corrected, measure the bearing oil clearance of the corrected journal or pin. Then select the main bearing
or connecting rod bearing. Rebored size calculation: D = A +B - C
where,
D: Bored diameter
A: Piston diameter as measured
B: Piston - to - bore clearance (standard value)
C: Honing allowance 0.02 mm (0.0008 in)
Standard : 63.940 - 63.964 mm (2.5173 - 2.5183 in)
Standard : 53.956 - 53.974 mm (2.1243 - 2.1250 in)

• SAE 5W-30 viscosity oil is preferred for all temperatures. If 5W-30
is not available, select the viscosity from the chart that is suitable
for the outside temperature range.
ANTI-FREEZE COOLANT MIXTURE RATIO
The engine cooling system is filled at the factory with a high-quality, long life, year-round, anti-freeze coolant
solution. The anti-freeze solution contains rust and corrosion inhibitors. Therefore, additional cooling system
additives are not necessary.
CAUTION:
• When adding or replacing coolant, be sure to use only Genuine NISSAN Long Life Anti-freeze cool-
ant or equivalent with the proper mixture ratio of 50% anti-freeze and 50% demineralized water or
distilled water.
• Other types of coolant solutions may damage your cooling system.
