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)
LUBRICANTNJHA0160S01Name: Nissan A/C System Oil Type S
Part number: KLH00-PAGS0
CHECKING AND ADJUSTINGNJHA0160S02Adjust the lubricant quantity according to the test group shown
below.
1 LUBRICANT RETURN OPERATION
Can lubricant return operation be performed?
A/C system works properly.
There is no evidence of a large amount of lubricant leakage.
YesorNo
Ye s G O T O 2 .
No GO TO 3.
2 PERFORM LUBRICANT RETURN OPERATION, PROCEEDING AS FOLLOWS
1. Start engine, and set the following conditions:
Test condition
Engine speed: Idling to 1,200 rpm
A/C switch: ON
Blower speed: Max. position
Temp. control: Optional [Set so that intake air temperature is 25 to 30°C (77 to 86°F).]
2. Perform lubricant return operation for about 10 minutes.
3. Stop engine.
CAUTION:
If excessive lubricant leakage is noted, do not perform the lubricant return operation.
GO TO 3.
3 CHECK COMPRESSOR
Should the compressor be replaced?
YesorNo
Yes GO TO HA-81.
No GO TO 4.

5. If a leak detector detects a leak, verify at least once by blow-
ing compressed air into area of suspected leak, then repeat
check as outlined above.
6. Do not stop when one leak is found. Continue to check for
additional leaks at all system components.
If no leaks are found, perform steps 7 - 10.
7. Start engine.
8. Set the heater A/C control as follows:
1) A/C switch ON.
2) Face mode
3) Recirculation position
4) Max cold temperature
5) Fan speed high
9. Run engine at 1,500 rpm for at least 2 minutes.
10. Turn engine off and perform leak check again following steps
4 through 6 above.
SHA839E
Refrigerant leaks should be checked immediately after
stopping the engine. Begin with the leak detector at the
compressor. The pressure on the high pressure side will
gradually drop after refrigerant circulation stops and pres-
sure on the low pressure side will gradually rise, as shown
in the graph. Some leaks are more easily detected when
pressure is high.
11. Discharge A/C system using approved refrigerant recovery
equipment. Repair the leaking fitting or component as neces-
sary.
12. Evacuate and recharge A/C system and perform the leak test
to confirm no refrigerant leaks.
13. Conduct A/C performance test to ensure system works
properly.

CAUTION:
Set charging current to value specified in Fig. 2. If charger is not capableof producing specified
current value, set its charging current as close to that value as possible.
Keep battery away from open flame while it is being charged.
When connecting charger, connect leads first, then turn on charger. Do notturn on charger first,
as this may cause a spark.
If battery temperature rises above 60°C (140°F), stop charging. Always charge battery when its
temperature is below 60°C (140°F).

Check battery type and determine the specified current using the table shown above.
After starting charging, adjustment of charging current is not necessary.
CAUTION:
Do not use quick charge method on a battery whose specific gravity is less than 1.100.
Set initial charging current to value specified in Fig. 6. If charger is notcapable of producing
specified current value, set its charging current as close to that value aspossible.
Keep battery away from open flame while it is being charged.
When connecting charger, connect leads first, then turn on charger. Do notturn on charger first,
as this may cause a spark.
Be careful of a rise in battery temperature because a large current flow is required during quick-
charge operation.
If battery temperature rises above 60°C (140°F), stop charging. Always charge battery when its
temperature is below 60°C (140°F).
Do not exceed the charging time specified in Fig. 6, because charging battery over the charging
time can cause deterioration of the battery.
