gas type NISSAN PATROL 2006 Service Manual

Dispose of used oil and used oil ®lters through authorized waste
disposal contractors to licensed waste disposal sites, or to the
waste oil reclamation trade. If in doubt, contact the local authority
for advice on disposal facilities.
It is illegal to pour used oil on to the ground, down sewers or drains,
or into water courses.
The regulations concerning the pollution of the environment
will vary from country to country.
Precautions for Fuel
GASOLINE ENGINE:
Three way catalyst equipped models ... unleaded gasoline of at
least 91 octane (RON)
CAUTION:
Do not use leaded gasoline. Using leaded gasoline will dam-
age the three way catalyst.
Except for the above models ... unleaded or leaded gasoline of
above 88 octane (RON)
Use unleaded fuel if instructed on the fuel ®ller lid.
DIESEL ENGINE*:
Diesel fuel of above 45 cetane for TD42 engine and above 50 cet-
ane for RD28ET engine
* If two types of diesel fuel are available, use summer or winter
fuel properly according to the following temperature conditions.
+Above þ7ÉC (20ÉF) ... Summer type diesel fuel.
+Below þ7ÉC (20ÉF) ... Winter type diesel fuel.
CAUTION:
+Do not use home heating oil, gasoline, or other alternate
fuels in your diesel engine. The use of those can cause
engine damage.
+Do not use summer fuel at temperature below þ7ÉC (20ÉF).
The cold temperature will cause wax to form in the fuel. As
a result, it may prevent the engine from running smoothly.
+Do not add gasoline or other alternate fuels to diesel fuel.
Precautions for Air Conditioning
Use an approved refrigerant recovery unit any time the air condi-
tioning system must be discharged. Refer to HA section (``HFC-
134a (R-134a) Service Procedure'', ``SERVICE PROCEDURES'')
for speci®c instructions.

General Refrigerant Precautions
WARNING:
+Do not release refrigerant into the air. Use approved recovery/recycling equipment to capture the
refrigerant every time an air conditioning system is discharged.
+Always wear eye and hand protection (goggles and gloves) when working with any refrigerant or
air conditioning system.
+Do not store or heat refrigerant containers above 52ÉC.
+Do not heat a refrigerant container with an open ¯ame; if container warming is required, place the
bottom of the container in a warm pail of water.
+Do not intentionally drop, puncture, or incinerate refrigerant containers.
+Keep refrigerant away from open ¯ames: poisonous gas will be produced if refrigerant burns.
+Refrigerant will displace oxygen, therefore be certain to work in well ventilated areas to prevent
suffocation.
+Do not introduce compressed air to any refrigerant container or refrigerant component.
Precautions for Refrigerant Connection
A new type refrigerant connection has been introduced to all refrigerant lines except the following location.
+Expansion valve to cooling unit
+A part of high-pressure line
FEATURES OF NEW TYPE REFRIGERANT CONNECTION
+The O-ring has been relocated. It has also been provided with a groove for proper installation. This elimi-
nates the chance of the O-ring being caught in, or damaged by, the mating part. The sealing direction of
the O-ring is now set vertically in relation to the contacting surface of the mating part to improve sealing
characteristics.
+The reaction force of the O-ring will not occur in the direction that causes the joint to pull out, thereby
facilitating piping connections.
CAUTION:
The new and former refrigerant connections use different O-ring con®gurations. Do not confuse
O-rings since they are not interchangeable. If a wrong O-ring is installed, refrigerant will leak at, or
around, the connection.

PRECAUTIONS AND PREPARATIONMANUAL AND AUTO
HA-2

WARNING:
Make sure all refrigerant is discharged into the recycling equipment and the pressure in the system
is less than atmospheric pressure. Then gradually loosen the discharge side hose ®tting and remove
it.
CAUTION:
When replacing or cleaning refrigerant cycle components, observe the following.
+When the compressor is removed, store it in the same position as it is when mounted on the car.
Failure to do so will cause lubricant to enter the low pressure chamber.
+When connecting tubes, always use a torque wrench and a back-up wrench.
+After disconnecting tubes, immediately plug all openings to prevent entry of dirt and moisture.
+When installing an air conditioner in the vehicle, connect the pipes as the ®nal 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 portions shown in illustration. Be careful not to apply
lubricant to threaded portion.
Lubricant name: Nissan A/C System Oil Type S
Part number: KLH00-PAGS0
+O-ring must be closely attached to in¯ated portion of tube.
+After inserting tube into union until O-ring is no longer visible, tighten nut to speci®ed torque.
+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 speci®ed torque.

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)

Supplemental Restraint System (SRS) ``AIR
BAG'' and ``SEAT BELT PRE-TENSIONER''
The Supplemental Restraint System such as ``AIR BAG'' and ``SEAT BELT PRE-TENSIONER'' used along with
a seat belt, helps to reduce the risk or severity of injury to the driver and front passenger in a frontal collision.
The SRS system composition which is available to NISSAN MODEL Y61 is as follows (The composition var-
ies according to the destination.):
Driver air bag module (located in the center of the steering wheel), front passenger air bag module (located
on the instrument panel on passenger side), seat belt pre-tensioner, a diagnosis sensor unit, warning lamp,
wiring harness and spiral cable.
Information necessary to service the system safely is included in theRS sectionof this Service Manual.
WARNING:
+To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag in¯ation, all maintenance must be performed
by an authorized NISSAN dealer.
+Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the RS section.
+Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. Spiral cable and wiring harnesses covered with yellow insulation either just before
the harness connectors or for the complete harness are related to the SRS.
Precautions for Steering System
+Before disassembly, thoroughly clean the outside of the unit.
+Disassembly should be done in a clean work area. It is important to prevent the internal parts from
becoming contaminated by dirt or other foreign matter.
+Place disassembled parts in order, on a parts rack, for easier and proper assembly.
+Use nylon cloths or paper towels to clean the parts; common shop rags can leave lint that might
interfere with their operation.
+Before inspection or reassembly, carefully clean all parts with a general purpose, non-¯ammable
solvent.
+Before assembly, apply a coat of recommended ATF* to hydraulic parts. Vaseline may be applied
to O-rings and seals. Do not use any grease.
+Replace all gaskets, seals and O-rings. Avoid damaging O-rings, seals and gaskets during instal-
lation. Perform functional tests whenever designated.
