Maintenance of Oil Qu antity in CompressorINFOID:0000000005930838
The oil in the compressor circulates through the system with the refrigerant. Add oil to compressor when
replacing any component or after a large refrigerant leakage occurred. It is important to maintain the specified
amount.
If oil quantity is not maintained properly , the following malfunctions may result:
• Lack of oil: May lead to a seized compressor.
• Excessive oil: Inadequate cooling (thermal exchange interference)

Checking of Refrigerant LeaksINFOID:0000000005930884
Perform a visual inspection of all refrigeration parts, fittings, hoses and components for signs of A/C oil leak-
age, damage and corrosion. A/C oil leakage may indicate an area of refrigerant leakage. Allow extra inspec-
tion time in these areas when using either an electronic refrigerant leak detector or fluorescent dye leak
detector.
If dye is observed, confirm the leak with an electronic refrigerant leak detector. It is possible a prior leak was
repaired and not properly cleaned.
When searching for leaks, do not stop when one leak is found but continue to check for additional leaks at all
system components and connections.
When searching for refrigerant leaks using an electronic leak detector, move the probe along the suspected
leak area at 25 to 50 mm (1 to 2 in) per second and no further than 1/4 inch from the component.
CAUTION:
Moving the electronic leak detector probe slower an d closer to the suspected leak area will improve
the chances of finding a leak.
Checking System for Leaks Using the Fluorescent Leak DetectorINFOID:0000000005930885
1. Check A/C system for leaks using the UV lamp and safety goggles J-42220 in a low sunlight area (area
without windows preferable). Illuminate all components, fittings and lines. The dye will appear as a bright
green/yellow area at the point of leakage. Fluoresce nt dye observed at the evaporator drain opening indi-
cates an evaporator core assembly (tubes, core or expansion valve) leak.
2. If the suspected area is difficult to see, use an adjustable mirror or wipe the area with a clean shop rag or cloth, with the UV lamp for dye residue.
3. After the leak is repaired, remove any residual dye using dye cleaner J-43872 to prevent future misdiag- nosis.
4. Perform a system performance chec k and verify the leak repair with an approved electronic refrigerant
leak detector.

Make sure the mounting conditions (looseness, backlash) of each component and component conditions
(wear, damage) are within specifications.
SHOCK ABSORBER INSPECTION
Check shock absorber for oil leakage, damage and replace it if necessary.
Wheel AlignmentInspectionINFOID:0000000005931085
DESCRIPTION
Measure wheel alignment under unladen conditions.
NOTE:
“Unladen conditions” means that fuel, engine coolant, and lubricant are full. Spare tire, jack, hand tools and
mats are in designated positions.
PRELIMINARY
Check the following:
1. Tires for improper air pressure and wear.
2. Road wheels for runout. Refer to WT-6
.
3. Wheel bearing axial end play. Refer to RAX-6, "
On-Vehicle Inspection and Service" .
4. Shock absorber operation.
5. Each mounting part of suspension for looseness and deformation.
6. Rear suspension beam for cracks, deformation, and other damage.
7. Vehicle height (posture).
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 ca pable 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 al ignment machine for their recommended Service/Cali-
bration Schedule.
THE ALIGNMENT PROCESS
IMPORTANT: Use only the alignment specifications listed in this Service Manual. Refer to RSU-13, "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.
2. Some newer alignment machines are equipped with an optional “Rolling Compensation” method to “com- pensate” the sensors (alignment targets or head units). Do NOT use this “Rolling Compensation”
method.
• Use the “Jacking Compensation” method. After inst alling the alignment targets or head units, raise the
vehicle and rotate the wheels 1/2 turn both ways.
• See Instructions in the alignment machine you are using for more information.
