2006 NISSAN PATROL maintenance

Precautions for Service Equipment
RECOVERY/RECYCLING EQUIPMENT
Follow the manufacturer's instructions for machine operation and
machine maintenance. Never introduce any refrigerant other than
that speci®ed into the machine.
ELECTRONIC LEAK DETECTOR
Follow the manufacture's instructions for tester operation and tester
maintenance.
VACUUM PUMP
The lubricant contained inside the vacuum pump is not compatible
with the speci®ed lubricant for HFC-134a (R-134a) A/C systems.
The vent side of the vacuum pump is exposed to atmospheric
pressure. So the vacuum pump lubricant may migrate out of the
pump into the service hose. This is possible when the pump is
switched off after evacuation (vacuuming) and hose is connected
to it.
To prevent this migration, use a manual valve situated near the
hose-to-pump connection, as follows.
+Usually vacuum pumps have a manual isolator valve as part of
the pump. Close this valve to isolate the service hose from the
pump.
+For pumps without an isolator, use a hose equipped with a
manual shut-off valve near the pump end. Close the valve to
isolate the hose from the pump.
+If the hose has an automatic shut off valve, disconnect the hose
from the pump: as long as the hose is connected, the valve is
open and lubricating oil may migrate.
Some one-way valves open when vacuum is applied and close
under a no vacuum condition. Such valves may restrict the pump's
ability to pull a deep vacuum and are not recommended.
MANIFOLD GAUGE SET
Be certain that the gauge face indicates R-134a or 134a. Make
sure the gauge set has 1/2²-16 ACME threaded connections for
service hoses. Con®rm the set has been used only with refrigerant
HFC-134a (R-134a) along with speci®ed lubricant.
SERVICE HOSES
Be certain that the service hoses display the markings described
(colored hose with black stripe). All hoses must include positive
shut off devices (either manual or automatic) near the end of the
hoses opposite the manifold gauge.

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 speci®ed 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)

Name: Nissan A/C System Oil Type S
Part number: KLH00-PAGS0
CHECKING AND ADJUSTING
Adjust the lubricant quantity according to the ¯owchart shown
below.
START
Can lubricant return operation be per-
formed?
+A/C system works properly.
+There is no evidence of a large amount of
lubricant leakage.
No
cYe s
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 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. 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.
Should the compressor be replaced?
No Yes

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
cYe s
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 ¯ow
chart.
*2: If refrigerant leak is small, no addition of lubricant is needed.
Carry out the A/C performance test.b

jA
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. 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.
14-16Nzm (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 ¯ oz) of lubricant at this time.
Do not add this 5 m!(0.2 Imp ¯ oz) of lubricant if only replacing the compressor.

Checking Refrigerant Leaks
PRELIMINARY CHECK
Perform a visual inspection of all refrigeration parts, ®ttings, hoses,
and components for signs of A/C lubricant leakage, damage and
corrosion.
PRECAUTIONS FOR HANDLING LEAK DETECTOR
When performing a refrigerant leak check, use an A/C leak detec-
tor 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
speci®ed maintenance.
Other gases in the work area or substances on the A/C
components, for example, anti-freeze, windshield washer
¯uid, solvents and cleaners, may falsely trigger the leak detec-
tor. 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 readings 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 ®tting completely with probe.
