4. Press UV lamp switch (5) and check A/C system for re frigerant leaks. (Where refrigerant leaks occur, flu-
orescent leak detection dye appears green in color.)
WARNING:
Do not look directly into UV lamp light source.
NOTE:
• For continuous operating time of UV lamp, fo llow the manufacturer’s operating instructions.
• Illuminate pipe joints from different angles using UV lamp to check for leaks.
• Use a mirror in areas that are di fficult to see to check for leaks.
• Refrigerant leaks from the evaporator can be detected by soaking a cotton swab or similar material with
drain hose water and illuminating it using the UV lamp.
• Dust, dirt, and packing material adhesives used for condenser, evaporator, and other components may fluoresce. Be careful not to misidentify leaks.
5. Repair or replace parts where refrigerant lea ks occur and wipe off fluorescent leak detection dye.
NOTE:
Completely wipe off fluorescent leak detection dye from gaps between parts, screw threads, and other
components using a cotton swab or similar material.
6. Use a UV lamp to check that no fluorescent leak detection dye remains after finishing work. WARNING:
Do not look directly into UV lamp light source.
NOTE:
• For continuous operating time of UV lamp, fo llow the manufacturer’s operating instructions.
• Dust, dirt, and packing material adhesives used for condenser, evaporator, and other components may

CHECK REFRIGERANT LEAKS USING ELECTRONIC LEAK DETECTOR
WARNING:
Do not check for refrigerant leaks while the engine is running.
CAUTION:
Be careful of the following items so that in accurate checks or misidentifications are avoided.
• Do not allow refrigerant vapor, shop chemical vapors, cigarette smoke or other contaminates around the vehicle.
• Always check refrigerant leaks in a low air flow en vironment so that refrigerant may not disperse.
1. Stop the engine.
2. Connect recovery/recycling/recharging equipment or manifold gauge set to the A/C service valves.
3. Check that A/C refrigerant pressure is 345 kPa (3.52 kg/cm
2, 50 psi) or more when temperature is 16 °C
(61 °F) or more. When pressure is lower than the specified value, recycle refrigerant completely and
recharge refrigerant to the specified level.
NOTE:
Leaks may not be detected if A/C refriger ant pressure is 345 kPa (3.52 kg/cm
2, 50 psi) or less when tem-
perature is less than 16° C (61°F).
4. Clean the area where the refrigerant leak check is performed and check for refrigerant leaks along all sur- faces of pipe connections and A/C system co mponents using electronic leak detector probe.
CAUTION:
• Continue checking once leaks are found. Always co ntinue and complete checking along all pipe
connections and A/C system comp onents for additional leaks.
• When leaks are detected, clean leak ar ea using compressed air and re-check.
• When checking the evaporator for leaks, always clean inside of drain hose so that the probe sur-
face may not be exposed to water or dirt.
NOTE:
• Always check for leaks starting from the high-pressure side and continue to the low-pressure side.
• When checking the evaporator for leaks, operate blower motor for 15 minut\
es or more at the maximum speed while the engine is stopped. Insert electronic leak detector probe into drain hose and hold for 10
minutes or more.
• When disconnecting shut-off valve that is connected to A/C service valve, always evacuate remaining
refrigerant so that misidentification can be avoided.
5. Repair or replace parts where refrigerant leaks occur.
6. Start the engine and set A/C control in the following conditions. • A/C switch: ON

O P
If possible, drive the vehicle with the customer until the noise is duplicated. Note any additional information on
the Diagnostic Worksheet regarding the conditions or lo cation of the noise. This information can be used to
duplicate the same conditions when you confirm the repair.
If the noise can be duplicated easily during the test drive, to help identify the source of the noise, try to dupli-
cate the noise with the vehicle stopped by doing one or all of the following:
1) Close a door.
2) Tap or push/pull around the area where the noise appears to be coming from.
3) Rev the engine.
4) Use a floor jack to recreate vehicle “twist”.
5) At idle, apply engine load (electrical load, half-clutch on M/T model, drive position on CVT and A/T models).
6) Raise the vehicle on a hoist and hit a tire with a rubber hammer.
• Drive the vehicle and attempt to duplicate the conditions the customer states exist when the noise occurs.
• If it is difficult to duplicate the noise, drive the vehicle slowly on an undulating or rough road to stress the
vehicle body.
CHECK RELATED SERVICE BULLETINS
After verifying the customer concern or symptom, check ASIST for Technical Service Bulletins (TSBs) related
to that concern or symptom.
If a TSB relates to the symptom, follow the procedure to repair the noise.
LOCATE THE NOISE AND IDENTIFY THE ROOT CAUSE
1. Narrow down the noise to a general area. To help pinpoint the source of the noise, use a listening tool (Chassis Ear: J-39570, Engine Ear: J-39565 and mechanic's stethoscope).
2. Narrow down the noise to a more specific area and identify the cause of the noise by: • removing the components in the area that you suspect the noise is coming from.Do not use too much force when removing clips and fasteners, otherwise clips and fasteners can be
broken or lost during the repair, resulting in the creation of new noise.
• tapping or pushing/pulling the component that you suspect is causing the noise.
Do not tap or push/pull the component with excessive force, otherwise the noise will be eliminated only
temporarily.
• feeling for a vibration with your hand by touching the component(s) that you suspect is (are) causing the
noise.
• placing a piece of paper between components that you suspect are causing the noise.
• looking for loose components and contact marks. Refer to IP-9, "
Generic Squeak and Rattle Troubleshooting".
REPAIR THE CAUSE
• If the cause is a loose component, tighten the component securely.
• If the cause is insufficient clearance between components:
- separate components by repositioning or loos ening and retightening the component, if possible.
- insulate components with a suitable insulator such as urethane pads, foam blocks, felt cloth tape or urethane tape. A NISSAN Squeak and Rattle Kit (J-50397) is available through your authorized NISSAN Parts Depart-
ment.
CAUTION:
Do not use excessive force as many components are constructed of plastic and may be damaged.
NOTE:
• Always check with the Parts Department for the latest parts information.
• The materials contained in the NISSAN Squeak and Rattle Kit (J-50397) are listed on the inside cover of the
kit; and can each be ordered separately as needed.
• The following materials not found in the kit can also be used to repair squeaks and rattles.
- SILICONE GREASE: Use instead of UHMW tape that will be visible or does not fit. The silicone grease will
only last a few months.
- SILICONE SPRAY: Use when grease cannot be applied.
- DUCT TAPE: Use to eliminate movement.
CONFIRM THE REPAIR
Confirm that the cause of a noise is repaired by test driving the vehicle. Operate the vehicle under the same
conditions as when the noise originally occurred. Refer to the notes on the Diagnostic Worksheet.
