fuel NISSAN PATROL 2006 Service Manual

General maintenance includes those items which should be checked during the normal day-to-day operation
of the vehicle. They are essential if the vehicle is to continue operating properly. The owners can perform the
checks and inspections themselves or they can have their NISSAN dealers do them.
Item Reference pages
OUTSIDE THE VEHICLE
The maintenance items listed here should be performed from time to time, unless otherwise
speci®ed.
TiresCheck the pressure with a gauge periodically when at a service station, including the
spare, and adjust to the speci®ed pressure if necessary. Check carefully for damage, cuts or
excessive wear.Ð
Windshield wiper bladesCheck for cracks or wear if they do not wipe properly. Ð
Doors and engine hoodCheck that all doors, the engine hood, the trunk lid and back door
operate properly. Also ensure that all latches lock securely. Lubricate hinges, latches, rollers and
links if necessary. Make sure that the secondary latch keeps the hood from opening when the
primary latch is released.
When driving in areas using road salt or other corrosive materials, check for lubrication fre-
quently.MA-27
Tire rotationTires should be rotated every 5,000 km (3,000 miles) for 4WD models. MA-25
INSIDE THE VEHICLE
The maintenance items listed here should be checked on a regular basis, such as when per-
forming periodic maintenance, cleaning the vehicle, etc.
LightsMake sure that the headlights, stop lights, tail lights, turn signal lights, and other lights
are all operating properly and installed securely. Also check headlight aim.Ð
Warning lights and chimesMake sure that all warning lights and chimes are operating prop-
erly.Ð
Steering wheelCheck for change in the steering conditions, such as excessive free play, hard
steering or strange noises.
Free play: Less than 35 mm (1.38 in)Ð
Seat beltsCheck that all parts of the seat belt system (e.g. buckles, anchors, adjusters and
retractors) operate properly and smoothly, and are installed securely. Check the belt webbing for
cuts, fraying, wear or damage.MA-27
UNDER THE HOOD AND VEHICLE
The maintenance items listed here should be checked periodically e.g. each time you check the
engine oil or refuel.
Windshield washer ¯uidCheck that there is adequate ¯uid in the tank. Ð
Engine coolant levelCheck the coolant level when the engine is cold. MA-14, 15
Engine oil levelCheck the level after parking the vehicle on a level spot and turning off the
engine.MA-13, 14
Brake and clutch ¯uid levelMake sure that the brake and clutch ¯uid levels are between the
``MAX'' and ``MIN'' lines on the reservoir.MA-20, 23
BatteryCheck the ¯uid level in each cell. It should be between the ``MAX'' and ``MIN'' lines. Ð

PERIODIC MAINTENANCE

Checking Cooling System
CHECKING HOSES AND CLAMPS
Check hoses and clamps for proper attachment, leaks, cracks,
damage, loose connections, cha®ng and deterioration.
CHECKING RADIATOR CAP
Apply pressure to radiator cap with cap tester to see if it is satis-
factory.
Radiator cap relief pressure:
78-98kPa
(0.78 - 0.98 bar, 0.8 - 1.0 kg/cm
2, 11 - 14 psi)
Pull the negative-pressure valve to open it. Check that it closes
completely when released.
CHECKING COOLING SYSTEM FOR LEAKS
Apply pressure to the cooling system with cap tester to check for
leakage.
Testing pressure:
98 kPa (0.98 bar, 1.0 kg/cm
2, 14 psi)
CAUTION:
Use of higher pressure than the speci®ed value may cause
damage to radiator.
Checking and Replacing Fuel Filter and
Draining Water
Be careful not to spill fuel in engine compartment. Place a rag
to absorb fuel.
CHECKING FUEL FILTER
Check fuel ®lter for fuel leakage, damage and other abnormal
signs.
REPLACING FUEL FILTER
1. Disconnect harness connector and drain fuel.

2. Remove fuel ®lter using band-type ®lter wrench.
Remove fuel ®lter and fuel ®lter sensor.
CAUTION:
Remove fuel ®lter without spilling fuel. If spilt, wipe off imme-
diately. Be specially careful not to spill fuel on engine mount
insulator.
3. Wipe clean fuel ®lter mounting surface on fuel ®lter bracket and
smear a little fuel on rubber seal of fuel ®lter.
4. Screw fuel ®lter on until a slight resistance is felt, then tighten
an additional more than 2/3 of a turn.
5. Install fuel ®lter sensor to new fuel ®lter.
6. Bleed air from fuel line.
Refer to Bleeding Fuel System in EC section.
7. Start engine and check for leaks.
DRAINING WATER
1. Drain water as follows.
Loosen drain cock and drain water.
Loosening drain cock 4 to 5 turns causes water to start drain-
ing. Do not remove drain cock by loosening it excessively.
If water does not drain properly, move the priming pump up and
down.
2. Bleed air.
Checking Fuel Lines
Check fuel lines and tank for proper attachment, leaks, cracks,
damage, loose connections, cha®ng and deterioration.
CAUTION:
Keep clean parts with compressed air when assembling.

Cleaning and Replacing Air Cleaner Filter
VISCOUS PAPER TYPE
The viscous paper type air cleaner ®lter does not require any clean-
ing operation between renewal.
Checking Injection Nozzle
WARNING:
When using nozzle tester, be careful not to allow diesel fuel
sprayed from nozzle to come into contact with your hand or
body, and make sure that your eyes are properly protected.
1. Install nozzle to injection nozzle tester and bleed air from ¯are
nut.
2. Check initial injection pressure by pumping tester handle one
full stroke per second.
Initial injection pressure:
Used nozzle
More than 14,220 kPa
(142.2 bar, 145 kg/cm
2, 2,062 psi)
New nozzle
14,711 - 15,495 kPa
(147.1 - 155.0 bar, 150 - 158 kg/cm
2,
2,133 - 2,247 psi)
+Always check initial injection pressure before installing
new nozzle.
3. Check spray pattern by pumping tester handle one full stroke
per second.
a. If main spray angle is within 30 degrees as shown, injec-
tion nozzle is good.
b. It is still normal even if a thin stream of spray deviates from
main spray (pattern B).
4. If initial injection pressure or injection nozzle is not normal,
adjust or clean injection nozzle.
5. Test again. If it is not corrected, replace nozzle.
Refer to EC section for injection pressure adjustment, clean-
ing and replacement.

6. Install all injection nozzles with Tool and securely connect fuel
spill tube and delivery tubes.
7. Bleed air from fuel system and check for fuel leakage with
engine running.
Injection nozzle to cylinder head:
:59-69Nzm (6.0 - 7.0 kg-m, 43 - 51 ft-lb)
Spill tube nut:
:39-49Nzm (4.0 - 5.0 kg-m, 29 - 36 ft-lb)
Injection tube:
:20-25Nzm (2.2 - 2.5 kg-m, 16 - 18 ft-lb)
Checking Idle Speed
Inspection should be carried out with gears in ``Neutral'' and
with air conditioner and other electrical loads off.
1. Warm up engine until engine coolant temperature indicator
points to the middle of gauge.
2. Attach a diesel tachotester's pick-up to No. 1 fuel injection tube.
3. Race engine two or three times and check idle speed.
Idle speed:

Checking Body Corrosion
Visually check the body sheet metal panel for corrosion, paint damage (scratches, chipping, rubbing, etc.) or
damage to the anti-corrosion materials. In particular, check the following locations.
Hemmed portion
Hood front end, door lower end, trunk lid rear end, etc.
Panel joint
Side sill of rear fender and center pillar, rear wheel housing of rear fender, around strut tower in engine
compartment, etc.
Panel edge
Trunk lid opening, sunroof opening, fender wheelarch ¯ange, fuel ®ller lid ¯ange, around holes in panel, etc.
Parts contact
Waist molding, windshield molding, bumper, etc.
Protectors
Damage or condition of mudguard, fender protector, chipping protector, etc.
Anti-corrosion materials
Damage or separation of anti-corrosion materials under the body.
Drain holes
Condition of drain holes at door and side sill.
When repairing corroded areas, refer to the Corrosion Repair Manual.

Precautions
+When installing rubber parts, ®nal tightening must be car-
ried out under unladen condition* with tires on ground.
*: Fuel, radiator coolant and engine oil full. Spare tire, jack,
hand tools and mats in designated positions.
+Use ¯are nut wrench when removing and installing brake
tubes.
+After installing removed suspension parts, check wheel
alignment and adjust if necessary.
+Always torque brake lines when installing.
