CleaningINFOID:0000000001381511
 It is very important not to scratch the gasket faces of any aluminium components.
 Use suitable tool to dissolve any part of the seal which remains stuck to the metal surface.
 Apply the dissolving product to the part to be cleaned, wait approximately 10 minutes, then remove it using a
wooden spatula.
 Wear gloves while carrying out this operation.
 Do not allow this dissolving product to drip on to the paintwork.
Great care should be taken when performing this operation, to prevent foreign objects from entering
the pipes taking oil under pressure to the camshafts (pipes in both the cylinder head and its cover)
and the oil return pipes.
Failure to follow these instructions could lead to the blocking of the oilways, resulting in rapid and
serious damage to the engine.

On-Vehicle Inspection and ServiceINFOID:0000000001716890
Make sure the mounting conditions (looseness, back lash) of each component and component conditions
(wear, damage) are normal.
INSPECTION OF LOWER BALL JOINT END PLAY
1. Set front wheels in a straight-ahead position. Do not depress brake pedal.
2. Place an iron bar or similar tool between transverse link and steering knuckle.
3. Measure axial end play by prying it up and down.
CAUTION:
Be careful not to damage ball joint boot. Do not damage the installation position by applying
excessive force.
STRUT INSPECTION
Check for oil leakage, damage and replace as necessary.
Wheel Alignment InspectionINFOID:0000000001716891
PRELIMINARY INSPECTION
WARNING:
Always adjust the alignment with the vehicle on a flat surface.
NOTE:
If alignment is out of specification, 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, coolant, and lubricant are full; and that the spare tire, jack, hand tools and mats are in
their 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-5, "
Inspection" .
4. Check the wheel bearing axial end play. Refer to FA X - 5 , "
On-Vehicle Inspection and Service" .
5. Check the shock absorbers for leaks or damage.
6. Check each mounting point of the suspension components 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-18, "
Wheelarch Height (Unladen*)" .
GENERAL INFORMATION AND RECOMMENDATIONS
1. A Four-Wheel Thrust Alignment should be performed.
 This type of alignment is recommended for any NISSAN 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 capable of accepting any NISSAN 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 alignment machine for their recommended Service/Cali-
bration Schedule.
THE ALIGNMENT PROCESS
IMPORTANT: Use only the alignment specifications listed in this Service Manual. Refer to FSU-17, "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. Axial end play : 0 mm (0 in)

PRECAUTIONS
General Refrigerant Precaution
INFOID:0000000001396430
WARNING:
 Avoid breathing A/C refrigerant and oil vapor or mist. Exposure may irritate eyes, nose and throat.
Use only approved recovery/recycling equipment to discharge HFC-134a (R-134a) refrigerant. If acci-
dental system discharge occurs, ventilate work area before resuming service. Additional health and
safety information may be obtained from refrigerant and oil manufacturers.
 Do not release refrigerant into the air. Use approved recovery/recycling equipment to capture the
refrigerant every time an air conditioning system is discharged.
 Always wear eye and hand protection (goggles and gloves) when working with any refrigerant or air
conditioning system.
 Do not store or heat refrigerant containers above 52°C (126° F).
 Do not heat a refrigerant container with an open flame; if container warming is required, place the
bottom of the container in a warm pail of water.
 Do not intentionally drop, puncture, or incinerate refrigerant containers.
 Keep refrigerant away from open flames: poisonous gas will be produced if refrigerant burns.
 Refrigerant will displace oxygen, therefore be certain to work in well ventilated areas to prevent suf-
focation.
 Do not pressure test or leak test HFC-134a (R-134a) service equipment and/or vehicle air condition-
ing systems with compressed air during repair. Some mixtures of air and HFC-134a (R-134a) have
been shown to be combustible at elevated pressures. These mixtures, if ignited, may cause injury or
property damage. Additional health and safety information may be obtained from refrigerant manu-
facturers.
Oil PrecautionINFOID:0000000001396431
 Use only specified oil for the HFC-134a (R-134a) A/C system and HFC-134a (R-134a) components. If oil
other than that specified is used, compressor malfunction is likely to occur.
 The specified HFC-134a (R-134a) oil rapidly absorbs moisture from the atmosphere. The following handling
precautions must be observed:
- When removing refrigerant components from a vehicle, immediately cap (seal) the component to minimize
the entry of moisture from the atmosphere.
- When installing refrigerant components to a vehicle, do not remove the caps (unseal) until just before con-
necting the components. Connect all refrigerant loop components as quickly as possible to minimize the
entry of moisture into system.
- Only use the specified oil from a sealed container. Immediately reseal containers of oil. Without proper seal-
ing, oil will become moisture saturated and should not be used.
 Avoid breathing A/C refrigerant and oil vapor or mist. Exposure may irritate eyes, nose and throat.
Use only approved recovery/recycling equipment to discharge HFC-134a (R-134a) refrigerant. If accidental
system discharge occurs, ventilate work area before resuming service. Additional health and safety informa-
tion may be obtained from refrigerant and oil manufacturers.
 Do not allow A/C oil to come in contact with styrofoam parts. Damage may result.
Precaution for Refrigerant ConnectionINFOID:0000000001396432
A new type refrigerant connection has been introduced to all refrigerant lines except the following location.
 Expansion valve to evaporator
 Refrigerant pressure sensor to condenser
