2000 NISSAN PATROL belt

Supplemental Restraint System (SRS) ªAIR
BAGº and ªSEAT BELT PRE-TENSIONERº
The Supplemental Restraint System such as ªAIR BAGº and ªSEAT BELT PRE-TENSIONERº used along
with a seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. The SRS system composition which is available to NISSAN MODEL Y61 is as follows (The
composition varies according to the destination and optional equipment.):
+For a frontal collision
The Supplemental Restraint System consists of 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-tensioners, a diagnosis sensor unit, warning lamp, wiring harness and spiral cable.
+For a side collision
The Supplemental Restraint System consists of front side air bag module (located in the outer side of
front seat), satellite sensor, diagnosis sensor unit (one of components of air bags for a frontal collision),
wiring harness, warning lamp (one of components of air bags for a frontal collision).
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 inflation, all maintenance should be per-
formed 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 tape either just
before the harness connectors or for the complete harness are related to the SRS.
Precautions for Fuel
DIESEL ENGINE*:
Diesel fuel of at least 50 cetane for ZD30DDTi engine
* If two types of diesel fuel are available, use summer or win-
ter fuel properly according to the following temperature con-
ditions.
+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 run-
ning smoothly.
+Do not add gasoline or other alternate fuels to diesel
fuel.

Supplemental Restraint System (SRS) ªAIR
BAGº and ªSEAT BELT PRE-TENSIONERº
The Supplemental Restraint System such as ªAIR BAGº and ªSEAT BELT PRE-TENSIONERº used along
with a seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. The SRS system composition which is available to NISSAN MODEL Y61 is as follows (The
composition varies according to the destination and optional equipment.):
+For a frontal collision
The Supplemental Restraint System consists of 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-tensioners, a diagnosis sensor unit, warning lamp, wiring harness and spiral cable.
+For a side collision
The Supplemental Restraint System consists of front side air bag module (located in the outer side of
front seat), satellite sensor, diagnosis sensor unit (one of components of air bags for a frontal collision),
wiring harness, warning lamp (one of components of air bags for a frontal collision).
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 inflation, all maintenance should be per-
formed 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 tape either just
before the harness connectors or for the complete harness are related to the SRS.
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
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 char-
acteristics.
+The reaction force of the O-ring will not occur in the direction that causes the joint to pull out, thereby
facilitating piping connections.

OIL FILTER
The oil filter is an element type. Refer to ªChanging Oil Filterº in
MA section.
Oil Cooler
REMOVAL AND INSTALLATION
1. Drain engine oil and coolant.
Remove catalyst and turbocharger. Refer to ªCATALYST
AND TURBOCHARGERº in EM section.
2. Remove bolts A to C then remove oil cooler assembly.
+Do not remove ªDº nuts when removing oil cooler
assembly.
Bolt length:
A: 20 mm (0.79 in)
B: 45 mm (1.77 in)
C: 65 mm (2.56 in)
3. Installation is in reverse order of removal.
+Do not spill coolant on the drive belt.
INSPECTION
1. Check oil cooler for cracks.
2. Check oil cooler for clogging by blowing through coolant inlet.
If necessary, replace oil cooler assembly.

Water Pump
CAUTION:
+When removing water pump assembly, be careful not to
get coolant on drive belt.
+Water pump cannot be disassembled and should be
replaced as a unit.
+Always replace with new gasket.
+After installing water pump, connect hose and clamp
securely, then check for leaks using radiator cap tester.
Refer to MA section.
REMOVAL AND INSTALLATION
1. Drain coolant from radiator and cylinder block.
Refer to MA section (ªChanging Engine Coolantº, ªENGINE
MAINTENANCEº).
2. Remove radiator upper hose.
3. Remove radiator shroud.
4. Remove cooling fan.
5. Remove drive belt. Refer to MA section, ªChecking Drive
Beltº.
6. Remove insulator.
7. Remove vacuum pipe.
8. Remove TDC sensor. Refer to TDC sensor removal and
installation in ªTIMING GEARº.
9. Remove fan coupling with water pump.
10. Install in the reverse order of removal.

11. Remove radiator.
12. After repairing or replacing radiator, install all removed parts
in reverse order of removal.
Cooling Fan (Crankshaft driven)
DISASSEMBLY AND INSTALLATION
+Do not release the drive belt tension by removing the fan/
water pump pulley.
+Fan coupling cannot be disassembled and should be
replaced as a unit. If front mark
jFis present, install fan so
that side marked
jFfaces the front.
+Proper alignment of these components is essential. Improper
alignment will cause them to wobble and may eventually
cause the fan to separate from the water pump causing
extensive damage.
