DTC DETECTION LOGIC
This diagnosis detects leaks in the EVAP line between f
uel tank and EVAP canister purge volume control sole-
noid valve, using the negative pressure caused by decrease of fuel temperature in the fuel tank after turning
ignition switch OFF.
If ECM judges there are no leaks, the diagnosis will be OK.
CAUTION:
• Use only a genuine NISSAN fuel filler cap as a replacemen t. If an incorrect fuel filler cap is used, the
MIL may illuminate.
• If the fuel filler cap is not tighte ned properly, the MIL may illuminate.
• Use only a genuine NISSAN rubber tube as a replacement.

WARNING:
Do not remove the radiator cap when the engine is hot. Serious burns could occur from high-pressure
engine coolant escaping from the radi ator. Wrap a thick cloth around the radiator cap. Slowly turn it a
quarter of a turn to release built-up pressure. Carefu lly remove radiator cap by turning it all the way.
NOTE:
When removing components such as hoses, tubes/lines, etc. , cap or plug openings to prevent fluid from spill-
ing.
REMOVAL
1. Drain engine coolant. Refer to CO-8, "Draining Engine Coolant".
CAUTION:
• Perform this step when engine is cold.
• Do not spill engine coolant on drive belt.
2. Remove air ducts and air cleaner assembly. Refer to EM-26, "
Removal and Installation".
3. Disconnect radiator hose (upper). Refer to CO-13, "
Exploded View".
4. Disconnect harness connector from engine coolant temperature sensor.
5. Disconnect harness connector from cylinder block heater (Canada only).
6. Disconnect water hoses and heater hoses from water outlet.
7. Remove water outlet.
8. Remove engine coolant temperature sens or from water outlet, if necessary.
9. Remove cylinder block heater from water outlet, if necessary (Canada only).
INSTALLATION
Installation is in the reverse order of removal.
CAUTION:
Do not reuse gasket.
INSPECTION AFTER INSTALLATION
• 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 MA-11, "
Fluids and Lubricants".
• Use procedure below to check for fuel leaks.
• Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leaks
at connection points.
• Start engine. With engine speed increased, che ck again for fuel leaks 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 leaks 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.

WHEEL ALIGNMENT
InspectionINFOID:0000000012430301
PRELIMINARY INSPECTION
WARNING:
Always adjust the wheel alignment with the vehicle on a flat surface.
NOTE:
If the wheel alignment is out of s pecification, inspect and replace any damaged or worn rear suspension parts
before making any adjustments.
1. Check and adjust the wheel alignment with the vehicle under unladen conditions. “Unladen conditions”
means that the fuel, engine coolant, and lubricants are full; the spare tire, jack, hand tools and mats are in
designated positions.
2. Check the tires for incorrect air pressure and excessive wear.
3. Check the wheels for run out and damage. Refer to WT-54, "
Wheel".
4. Check the wheel bearing axial end play. Refer to FAX-27, "
Wheel Bearing".
5. Check the shock absorbers for leaks or damage.
6. Check each mount point of the suspension co mponents for any excessive looseness or damage.
7. Check each link, arm, and the suspension member for any damage.
8. Check the vehicle height. Refer to FSU-21, "
Wheelarch Height (Unladen*)".
GENERAL INFORMATION AND RECOMMENDATIONS
1. A Four-Wheel Thrust Alignment should be performed.
• This type of alignment is recomm ended for any NISSAN/INFINITI vehicle.
• The four-wheel “thrust” process helps ensure that the vehicle is properly aligned and the steering wheel
is centered.
• The alignment machine itself should be capabl e of accepting any NISSAN/INFINITI vehicle.
• The alignment machine should be checked to ensure that it is level.
2. Make sure the alignment machine is properly calibrated. • Your alignment machine should be regularly calibrated in order to give correct information.
• Check with the manufacturer of your specific a lignment machine for their recommended Service/Cali-
bration Schedule.
ALIGNMENT PROCESS
IMPORTANT: Use only the alignment specifications listed in this Service Manual. Refer to FSU-20, "Wheel
Alignment (Unladen*1)".
• When displaying the alignment settings, many alignment machines use “indicators”: (Green/red, plus or
minus, Go/No Go). Do NOT use these indicators.
- The alignment specifications programmed into your alignment machine that operate these indicators may
not be correct.
- This may result in an ERROR.
• Most camera-type alignment machines are equipped with "Rolling Compensation" method and optional
"Jacking Compensation" method to "compensate" the alignment targets or head units.
"Rolling Compensation" is the preferred method.
- If using the "Rolling Compensation" method, after inst alling the alignment targets or head units, push or pull
on the rear wheel to move the vehicle. Do not push or pull on the vehicle body.
- If using the "Jacking Compensation" method, after inst alling the alignment targets or head units, raise the
vehicle and rotate the wheels 1/2 turn in either direction.
NOTE:
Do not use the "Rolling Compensation" method if you are using sensor-type alignment equipment.
• Follow all instructions for the alignment machine you're using for more information.
CAMBER, CASTER AND KINGPIN INCLINATION ANGLES INSPECTION
• Camber, caster, kingpin inclination angles cannot be adjusted.
• Before inspection, set the front wheels onto a turning radius gauge. Set the rear wheels onto a pad that has
the same height so the vehicle will remain horizontal.
TOTAL TOE-IN INSPECTION
Measure the total toe-in using the following procedure.

• After connecting the fuel tu
be quick connectors, make sure
the quick connectors are secure.
Check that the connector and r esin tube do not contact any
adjacent parts.
- a) Apply fuel pressure to the fu el system by turning the igni-
tion switch to ON (without starting the engine). Then check for
fuel leaks at the fuel tube connections.
- b) Start the engine and rev the engine, then check for fuel leaks at the fuel tube connections.
• After installing the tubes, run the engine and check for fuel
leaks at the connections.
• Use only a Genuine NISSAN fuel filler cap as a replacement. If
an incorrect fuel fi ller cap is used, the MIL may come on.
• For servicing “Evaporative Emi ssion System” parts, refer to
EC-473, "Inspection".
