Maintenance of Lubricant Quantity in
Compressor
The lubricant used to lubricate 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:
lLack of lubricant: May lead to a seized compressor
lExcessive lubricant: Inadequate cooling (thermal exchange
interference)
LUBRICANT
Name: Nissan A/C System Oil Type R
Part number: KLH00-PAGR0
CHECKING AND ADJUSTING
Adjust the lubricant quantity according to the flowchart shown
below.
START
Can lubricant return operation be per-
formed?
lA/C system works properly.lThere is no evidence of a large amount of
lubricant leakage.
No
cYes
Perform lubricant return operation, proceeding as follows:
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
1. Start engine, and set the following conditions:
lTest condition
Engine speed: Idling to 1,200 rpm
A/C or AUTO switch: ON
Blower speed: Max. position
Temp. control: Optional [Set so that intake air temperature is
25 to 30ÉC (77 to 86ÉF).]
2. Next item is for V-5 or V-6 compressor. Connect the manifold
gauge, and check that the high pressure side pressure is 588 kPa
(5.9 bar, 6 kg/cm
2, 85 psi) or higher.
If less than the reference level, attach a cover to the front face of
the condenser to raise the pressure.
3. Perform lubricant return operation for about 10 minutes.
4. Stop engine.
CAUTION:
If excessive lubricant leakage is noted, do not perform the lubricant
return operation.
Should the compressor be replaced?
No Yes

VA(Go to next page.)
Is there any part to be replaced?
(Evaporator, condenser, liquid tank or in
case there is evidence of a large amount of
lubricant leakage.)
No
cYes
After replacing any of the following major components, add the correct
amount of lubricant to the system.
Amount of lubricant to be added
*1: If compressor is replaced, addition of lubricant is included in the flow
chart.
*2: If refrigerant leak is small, no addition of lubricant is needed.
Carry out the A/C performance test.b

SERVICE PROCEDURES

VA
1. Discharge refrigerant into the refrigerant recovery/recycling equipment. Measure lubricant discharged into the recovery/
recycling equipment.
2. Remove the drain plug of the ``old'' (removed) compressor (applicable only to V-5, V-6, DKS-16H or DKS-17CH compressor).
Drain the lubricant into a graduated container and record the amount of drained lubricant.
3. Remove the drain plug and drain the lubricant from the ``new'' compressor into a separate, clean container.
4. Measure an amount of new lubricant installed equal to amount drained from ``old'' compressor. Add this lubricant to ``new''
compressor through the suction port opening.
5. Measure an amount of new lubricant equal to the amount recovered during discharging. Add this lubricant to ``new'' compres-
sor through the suction port opening.
6. Torque the drain plug.
V-5 or V-6 compressor: 18 - 19 Nzm (1.8 - 1.9 kg-m, 13 - 14 ft-lb)
DKS-16H compressor: 14 - 16 Nzm (1.4 - 1.6 kg-m, 10 - 12 ft-lb)
DKS-17CH compressor: 14 - 16 Nzm (1.4 - 1.6 kg-m, 10 - 12 ft-lb)
7. If the liquid tank also needs to be replaced, add an additional 5 m!(0.2 Imp fl oz) of lubricant at this time.
Do not add this 5 m!(0.2 Imp fl oz) of lubricant if only replacing the compressor.

Checking Refrigerant Leaks
PRELIMINARY CHECK
Perform a visual inspection of all refrigeration parts, fittings,
hoses, and components for signs of A/C lubricant leakage, dam-
age and corrosion.
PRECAUTIONS FOR HANDLING LEAK DETECTOR
When performing a refrigerant leak check, use an A/C leak
detector or equivalent. Ensure that the instrument is calibrated
and set properly per the operating instructions.
The leak detector is a delicate device. In order to use the leak
detector properly, read the operating instructions and perform
any specified maintenance.
Other gases in the work area or substances on the A/C
components, for example, anti-freeze, windshield washer
fluid, solvents and cleaners, may falsely trigger the leak
detector. Make sure the surfaces to be checked are clean.
Do not allow the sensor tip of the detector to come into
contact with any substance. This can also cause false read-
ings and may damage the detector.
1. Position probe approximately 5 mm (3/16 in) away from point
to be checked.
2. When testing, circle each fitting completely with probe.
