PRECAUTIONS
• Explain to the customer that environmental regulations prohibit the release of contaminated refrigerant into
the atmosphere.
• Explain that recovery of the contaminated refrigerant could damage service equipment and refrigerant sup-
ply.
• Suggest the customer return the vehicle to the location of previous service where the contamination may
have occurred.
• In case of repairing, recover the refrigerant using only dedicated equipment and containers. Do not
recover contaminated refrigerant into the existing service equipment. Contact a local refrigerant prod-
uct retailer for available service if the facility does not have dedicated recovery equipment. This refrigerant
must be disposed of in accordance with all federal and local regulations. In addition, replacement of all
refrigerant system components on the vehicle is recommended.
• The air conditioner warranty is void if the vehicle is within the warranty period. Please contact Nissan Cus-
tomer Affairs for further assistance.
COMPRESSOR
CAUTION:
• Plug all openings to prevent moisture and foreign matter from entering.
• Store it in the same way as it is when mounted on the car when the compressor is removed.
• Follow “Maintenance of Oil Quantity in Compressor” exactly when replacing or repairing compres-
sor. Refer to
.
• Keep friction surfaces between clutch and pulley clean. Wipe it off by using a clean waste cloth
moistened with thinner if the surface is contaminated with oil.
• Turn the compressor shaft by hand more than five turns in both directions after compressor service
operation. This distributes oil equally inside the compressor. Let the engine idle and operate the
compressor for one hour after the compressor is installed.
• Apply voltage to the new one and check for normal operation after replacing the compressor magnet
clutch.
LEAK DETECTION DYE
CAUTION:
• The A/C system contains a fluorescent leak detection dye used for locating refrigerant leakages. An
ultraviolet (UV) lamp is required to illuminate the dye when inspecting for leakages.
• Always wear fluorescence enhancing UV safety goggles to protect eyes and enhance the visibility of
the fluorescent dye.
• The fluorescent dye leak detector is not a replacement for an electrical leak detector (SST: J-41995).
The fluorescent dye leak detector should be used in conjunction with an electrical leak detector
(SST: J-41995) to pin-point refrigerant leakages.
• Read and follow all manufacture’s operating instructions and precautions prior to performing the
work for the purpose of safety and customer’s satisfaction.
• A compressor shaft seal should not necessarily be repaired because of dye seepage. The compres-
sor shaft seal should only be repaired after confirming the leakage with an electrical leak detector
(SST: J-41995).
• Always remove any remaining dye from the leakage area after repairs are completed to avoid a mis-
diagnosis during a future service.
• Do not allow dye to come into contact with painted body panels or interior components. Clean imme-
diately with the approved dye cleaner if dye is spilled. Fluorescent dye left on a surface for an
extended period of time cannot be removed.
• Do not spray the fluorescent dye cleaning agent on hot surfaces (engine exhaust manifold, etc.).
• Do not use more than one refrigerant dye bottle [1/4 ounce (7.4 cc)] per A/C system.
• Leak detection dyes for HFC-134a (R-134a) and CFC-12 (R-12) A/C systems are different. Do not use
HFC-134a (R-134a) leak detection dye in CFC-12 (R-12) A/C system or CFC-12 (R-12) leak detection
dye in HFC-134a (R-134a) A/C system or A/C system damage may result.
• The fluorescent properties of the dye remains for three or more years unless a compressor malfunc-
tion occurs.
NOTE:
Identification
• Vehicles with factory installed fluorescent dye have a green label.
• Vehicles without factory installed fluorescent dye have a blue label.

Be certain that the gauge face indicates R-134a or 134a. Make sure
the gauge set has 1/2
″-16 ACME threaded connections for service
hoses. Confirm the set has been used only with refrigerant HFC-
134a (R-134a) along with specified oil.
SERVICE HOSES
Be certain that the service hoses display the markings described
(colored hose with black stripe). All hoses must include positive shut-
off devices (either manual or automatic) near the end of the hoses
opposite the manifold gauge.
SERVICE COUPLERS
Do not attempt to connect HFC-134a (R-134a) service couplers to a
CFC-12 (R-12) A/C system. The HFC-134a (R-134a) couplers will
not properly connect to the CFC-12 (R-12) system. However, if an
improper connection is attempted, discharging and contamination
may occur.
