OIL PUMP BODY INNER DIAMETER
–Measure the inner diameter of oil pump body with inside
micrometer. (Position 6)
OIL PUMP INNER DIAMETER TO OIL PUMP BODY CLEARANCE
–(Clearance) = (Oil pump body inner diameter) – (Oil pump inner rotor outer diameter)

If measured/calculated values are out of the standard, replace oil pump assembly.
Regulator Valve Clearance
(Clearance) = D1 (Valve hole diameter) – D2 (Regulator valve outer
diameter of valve)

If out of the standard, replace oil pump assembly.
CAUTION:

Coat regulator valve with engine oil.

Make sure that it falls smoothly into regulator valve hole by
its own weight.
ASSEMBLY
Note to the following, and assemble in the reverse order of disassembly.

Install oil pump inner rotor and oil pump outer rotor with the
punched marks on the oil pump cover side.

GENERAL MAINTENANCE
Revision: 2004 November 2004 FX35/FX45
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).Parking brakeCheck that the pedal has the proper travel and make sure that the vehicle is
held securely on a fairly steep hill when only the parking brake is applied.PB-2
Automatic transmis-
sion "Park" mecha-
nismCheck that the lock release button on the selector lever operates properly and
smoothly. On a fairly steep hill check that the vehicle is held securely with the
selector lever in the P (Park) position without applying any brakes.— ItemReference page
ItemReference page
Windshield washer
fluidCheck that there is adequate fluid in the tank. —
Engine coolant levelCheck the coolant level when the engine is cold.MA-15
, MA-21
Radiator and hosesCheck the front of the radiator and clean off any dirt, insects, leaves, etc., that
may have accumulated. Make sure the hoses have no cracks, deformation,
deterioration or loose connections.—
Brake fluid levelMake sure that the brake fluid level is between the “MAX” and “MIN” lines on
the reservoir.MA-34

BatteryCheck the fluid level in each cell. It should be between the “MAX” and “MIN”
lines. Vehicles operated in high temperatures or under severe conditions
require frequent checks of the battery fluid level.SC-5, "
CHECKING
ELECTROLYTE LEVEL"
Engine drive beltsMake sure that no belt is frayed, worn, cracked or oily.MA-14, MA-21
Engine oil levelCheck the level on the oil level gauge after parking the vehicle on a level spot
and turning off the engine.MA-17, MA-24
Power steering fluid
level and linesCheck the level on the dipstick with the engine off. Check the lines for improper
attachment, leaks, cracks, etc.MA-36
Exhaust systemMake sure there are no loose supports, cracks or holes. If the sound of the
exhaust seems unusual or there is a smell of exhaust fumes, immediately
locate the trouble and correct it.MA-28
UnderbodyThe underbody is frequently exposed to corrosive substances such as those
used on icy roads or to control dust. It is very important to remove these sub-
stances, otherwise rust will form on the floor pan, frame, fuel lines and around
the exhaust system. At the end of winter, the underbody should be thoroughly
flushed with plain water, being careful to clean those areas where mud and dirt
can easily accumulate.—
Fluid leaksCheck under the vehicle for fuel, oil, water or other fluid leaks after the vehicle
has been parked for a while. Water dripping from the air conditioner after use is
normal. If you should notice any leaks or gasoline fumes are evident, check for
the cause and correct it immediately.—

NOTE:
(1) After 60,000 miles (96,000 km) or 48 months, inspect every 15,000 miles (24,000 km) or 12 months. Replace the drive belts if found
damaged or if the auto belt tensioner reading (only for VK45DE engine) reaches the maximum limit.
(2) If operating mainly in dusty conditions, more frequent maintenance may be required.
(3) Maintenance-free item. For service procedures, refer to FL section.
(4) After 60,000 miles (96,000 km) or 48 months, replace every 30,000 miles (48,000 km) or 24 months.
(5) If valve noise increases, inspect valve clearance.
* Maintenance items and intervals with “*” are recommended by INFINITI for reliable vehicle operation. The owner need not perform
such maintenance in order to maintain the emission warranty or manufacturer recall liability. Other maintenance items and intervals are
required.

PERIODIC MAINTENANCE
Revision: 2004 November 2004 FX35/FX45
NOTE:
(1) If towing a trailer, using a camper or a car-top carrier, or driving on rough or muddy roads, change (not just inspect) fluid (A/T, trans-
fer)/oil at every 30,000 miles (48,000 km) or 24 months. Using automatic transmission fluid other than Genuine NISSAN Matic J
ATF will cause deterioration in driveability and automatic transmission durability, and may damage the automatic transmis-
sion, which is not covered by the INFINITI new vehicle limited warranty.
(2) Refer to “Tire rotation” under the “General maintenance” heading earlier in this section.

SAE Viscosity NumberALS000G9
GASOLINE ENGINE OIL
SAE 5W-30 viscosity oil is preferred for all temperatures. SAE
10W-30 and 10W-40 viscosity oil may be used if the ambient
temperature is above -18°C (0°F)
Anti-Freeze Coolant Mixture RatioALS000GA
The engine cooling system is filled at the factory with a high-quality,
year-round, anti-freeze coolant solution. The anti-freeze solution
contains rust and corrosion inhibitors. Therefore, additional cooling
system additives are not necessary.
CAUTION:
When adding or replacing coolant, be sure to use only Genuine
NISSAN Long Life Antifreeze/ Coolant or equivalent with the
proper mixture ratio of 50% anti-freeze and 50% demineralized
water/distilled water.
Other types of coolant solutions may damage your cooling sys-
tem.
