Removal and Installation (Hatchback)NJBT0034+When removing or installing back door, place a cloth or other padding on back door. This prevents vehicle
body from being scratched.
+Bumper fascia is made of plastic. Do not use excessive force and be sure to keep oil away from it.
+Back door adjustment: Adjust at hinge-back door portion for proper back door fit.
+Back door lock system adjustment: Adjust striker so that it is in the center of the lock. After adjustment,
check back door lock operation.
+After installation, make sure that back door and fuel filler lid open smoothly.

+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.

+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.

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-86.
+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.

Maintenance of Lubricant Quantity in
Compressor
NJHA0160The lubricant in the compressor circulates through the system with
the refrigerant. Add lubricant to compressor when replacing any
component or after a large gas leakage occurred. It is important to
maintain the specified amount.
If lubricant quantity is not maintained properly, the following mal-
functions may result:
+Lack of lubricant: May lead to a seized compressor
+Excessive lubricant: Inadequate cooling (thermal exchange
interference)
