Checking Exhaust SystemNJFE0010Check exhaust pipes, muffler and mounting for improper
attachment, leaks, cracks, damage, chafing or deterioration.
Removal and InstallationNJFE0005CAUTION:
+Always replace exhaust gaskets with new ones when
reassembling.
+With engine running, check all tube connections for
exhaust gas leaks, and entire system for unusual noises.
+Check to ensure that mounting brackets and mounting
insulators are installed properly and free from undue
stress. Improper installation could result in excessive
noise or vibration.
+Discard any heated oxygen sensor which has been
dropped from a height of more than 0.5 m (19.7 in) onto a
hard surface such as a concrete floor; use a new one.
+Before installing a new oxygen sensor, clean exhaust sys-
tem threads using oxygen sensor thread cleaner tool and
apply anti-seize lubricant.
+Do not overtorque the oxygen sensor. Doing so may
cause damage to the oxygen sensor, resuiting in the MIL
coming on.
+Be sure to use genuine exhaust system parts which are
designed especially for heat resistance, corrosion
resistance, and shape.
+Perform the operation with the exhaust system fully
cooled down because the system will be heated just after
the engine stops.
+Be careful not to cut your hand on the insulator edge.

O-RING AND REFRIGERANT CONNECTIONNJHA0115S02
RHA790H
CAUTION:
The new and former refrigerant connections in some systems use different O-ring configurations. Do
not confuse O-rings since they are not interchangeable. If a wrong O-ring is installed, refrigerant will
leak at, or around, the connection.

WARNING:
Make sure all refrigerant is discharged into the recycling equipment and the pressure in the system
is less than atmospheric pressure. Then gradually loosen the discharge side hose fitting and remove
it.
CAUTION:
When replacing or cleaning refrigerant cycle components, observe the following.
+When the compressor is removed, store it in the same position as it is when mounted on the car.
Failure to do so will cause lubricant to enter the low pressure chamber.
+When connecting tubes, always use a torque wrench and a back-up wrench.
+After disconnecting tubes, immediately plug all openings to prevent entry of dirt and moisture.
PRECAUTIONS
Precautions for Refrigerant Connection (Cont'd)
HA-4

+When installing an air conditioner in the vehicle, connect the pipes as the final stage of the opera-
tion. Do not remove the seal caps of pipes and other components until just before required for
connection.
+Allow components stored in cool areas to warm to working area temperature before removing seal
caps. This prevents condensation from forming inside A/C components.
+Thoroughly remove moisture from the refrigeration system before charging the refrigerant.
+Always replace used O-rings.
+When connecting tube, apply lubricant to circle of the O-rings shown in illustration. Be careful not
to apply lubricant to threaded portion.
Lubricant name: Nissan A/C System Oil Type R for DKV-11G compressor
Part number: KLH00-PAGR0
Lubricant name: Nissan A/C System Oil Type S for CSV613 compressor
Part number: KLH00-PAGS0
+O-ring must be closely attached to dented portion of tube.
+When replacing the O-ring, be careful not to damage O-ring and tube.
+Connect tube until you hear it click, then tighten the nut or bolt by hand until snug. Make sure that
the O-ring is installed to tube correctly.
+After connecting line, conduct leak test and make sure that there is no leakage from connections.
When the gas leaking point is found, disconnect that line and replace the O-ring. Then tighten
connections of seal seat to the specified torque.
RHA861F
Precautions for Servicing CompressorNJHA0116+Plug all openings to prevent moisture and foreign matter from entering.
+When the compressor is removed, store it in the same position as it is when mounted on the car.
+When replacing or repairing compressor, follow ªMaintenance of Lubricant Quantity in Compres-
sorº exactly. Refer to HA-80.
+Keep friction surfaces between clutch and pulley clean. If the surface is contaminated, with
lubricant, wipe it off by using a clean waste cloth moistened with thinner.
+After compressor service operation, turn the compressor shaft by hand more than five turns in
both directions. This will equally distribute lubricant inside the compressor. After the compressor
is installed, let the engine idle and operate the compressor for one hour.
+After replacing the compressor magnet clutch, apply voltage to the new one and check for normal
operation.
