Precautions for Servicing Compressor
IAttach a blind plug to the suction port (low pressure) and discharge port (high pressure) of the
compressor to prevent oil from leaking out and dust from getting inside.
I When the compressor is removed, store it under the same condition as it is when mounted on the
car.
I When replacing or repairing compressor, be sure to remove oil from the compressor and check
the oil quantity extracted.
I When replacing with a new compressor, be sure to remove oil from the new compressor so that
the quantity of oil remaining in the new compressor is equal to the quantity collected from the
removed compressor. See the section ªLUBRICATION OILº.
I Pay attention so as not to allow dirt and oil to attach on the friction surfaces between clutch and
pulley. If the surface is contaminated, with oil, wipe it off by using a clean waste cloth moistened
with thinner.
I After completing the compressor service operation, be sure to rotate the compressor shaft more
than five turns in both directions by hand to equalize oil distribution inside the compressor, then
run the compressor for about one hour by idling the engine.
I When the compressor magnet clutch has been replaced, be sure to check the magnet clutch for
normal operation by applying voltage to the clutch.

Lubrication Oil
Name: Nissan A/C System Oil Type S
Part number: KLH00-PAGS0
Maintenance of Oil Quantity in Compressor
The oil used to lubricate the compressor circulates through the
system with the refrigerant. Whenever any component of the sys-
tem is replaced or a large amount of gas leakage occurs, add oil
to the compressor to maintain the specified amount.
If oil quantity is not maintained properly, the following malfunctions
may result:
ILack of oil: May lead to a seized compressor
I Excessive oil: Inadequate cooling (thermal exchange impeded)
Checking and Adjusting
Adjust the oil quantity according to the flowchart shown below.

Operation Check
The purpose of the operational check is to confirm that the system
is as it should be. The systems which will be checked are the
blower, mode (discharge air), intake air, temperature decrease,
temperature increase and A/C switch system.
CONDITIONS:
Engine running and at normal operating temperature.
PROCEDURE:
1. Check blower
1) Turn FAN CONTROL DIAL to 1.Blower should operate at speed 1.
2) Then turn the DIAL to speed 2.
3) Continue checking blower speed until all speeds are checked.
4) Leave blower on speed 4.
2. Check discharge air
1) Turn AIR CONTROL DIAL toposition.
2) Confirm that all discharge air comes out of face vents.
3) Turn AIR CONTROL DIAL to
position.
4) Confirm that discharge air comes out of face vents and foot vents.
5) Turn AIR CONTROL DIAL to
position.
6) Confirm that discharge air comes out of foot vents, with some air from face vents.
7) Turn AIR CONTROL DIAL to
position.
8) Confirm that discharge air comes out of foot vents with some air from defroster vents.
9) Turn AIR CONTROL DIAL to
position.
10) Confirm that all discharge air comes out of defroster vents, with some air from face vents.
3. Check recirculation
1) Switch AIR RECIRCULATION SWITCH to ON position (Indica-tor light ON).
2) Listen for intake door position change (you should hear sound change slightly).

TROUBLE DIAGNOSES FOR ABNORMAL PRESSURE
Whenever abnormal pressure of high and/or low sides of the system is noted, diagnosis must be conducted
by using a manifold gauge. The large-line zone on the gauge scale (see illustrations.) shown in the following
table refers to the standard (normal) pressure range for the corresponding pressure side (high or low). Since
the standard (normal) pressure, however, differs from vehicle to vehicle, refer to the ªAmbient air temperature-
to-compressor pressure tableº.

sides are too high.

How to Handle Battery
CAUTION:
If it becomes necessary to start the engine with a booster bat-
tery and jumper cables,
1) Use a 12-volt booster battery.
2) After connecting battery cables, ensure that they aretightly clamped to battery terminals for good contact.
METHODS OF PREVENTING OVER-DISCHARGE
The following precautions must be taken to prevent over-discharg-
ing a battery.
IThe battery surface (particularly its top) should always be kept
clean and dry.
I The terminal connections should be clean and tight.
I At every routine maintenance, check the electrolyte level.
This also applies to batteries designated as ªlow maintenanceº
and ªmaintenance-freeº.
I When the vehicle is not going to be used over a long period of
time, disconnect the negative battery terminal.
I Check the charge condition of the battery.
Periodically check the specific gravity of the electrolyte. Keep
a close check on charge condition to prevent over-discharge.
CHECKING ELECTROLYTE LEVEL
WARNING:
Do not allow battery fluid to come in contact with skin, eyes,
fabrics, or painted surfaces. After touching a battery, do not
touch or rub your eyes until you have thoroughly washed your
hands. If acid contacts eyes, skin or clothing, immediately
flush with water for 15 minutes and seek medical attention.

Bulb Replacement
The headlamp is a semi-sealed beam type which uses a replacable
halogen bulb. The bulb can be replaced from the engine compart-
ment side without removing the headlamp body.
IGrasp only the plastic base when handling the bulb. Never
touch the glass envelope.
1. Disconnect the battery cable.
2. Disconnect the harness connector from the back side of the bulb.
3. Pull off the rubber cap.
4. Press end of the retaining pin together to release bulb.
5. Remove the headlamp bulb. Do not shake or rotate the bulb when removing it.
6. Install the new bulb in reverse order of removal.
CAUTION:
I Do not leave headlamp reflector without bulb for a long
period of time as dust, moisture, smoke, etc. may enter the
headlamp body and affect the performance of the head-
lamp. Thus, the headlamp bulb should not be removed
from the headlamp reflector until just before a replacement
bulb is to be installed.
Aiming Adjustment
When performing headlamp aiming adjustment, use an aiming
machine, aiming wall screen or headlamp tester. For operating
instructions, of any aimer, it should be in good repair, calibrated and
used according to respective operation manuals supplied with the
unit.
For details, refer to the regulations in your own country.
Before performing aiming adjustment, check the following:
a. Keep all tires inflated to correct pressures.
b. Place vehicle and tester on one and same flat surface.
c. See that there is noload in vehicle other than coolant,
engine oil filled up to correct level, full fuel tank and the
driver (or equivalent weight placed in driver's position).
CAUTION:
Be sure aiming switch is set to ª0º when performing aiming
adjustment on vehicles equipped with headlamp aiming con-
trol.
