Changing Engine OilNBS004QD
WAR NING :
Be careful not to burn yourself, as engine oil may be hot.
Prolonged and repeated contact with used engine oil may
cause skin cancer; try to avoid direct skin contact with
used engine oil. If skin contact is made, wash thoroughly
with soap or hand cleaner as soon as possible.
1. Warm up engine, put vehicle horizontally and check for engine
oil leakage from engine components. Refer to LU-26, "
ENGINE
OIL LEAKAGE" .
2. Stop engine and wait for 15 minutes.
3. Loosen oil filler cap.
4. Remove mounting bolts, and then pull down the rear of front engine undercover and secure it using clip.
5. Remove drain plug and then drain engine oil.
6. Install drain plug with new washer. Refer to EM-187, "
OIL PAN AND OIL STRAINER" .
CAUTION:
Be sure to clean drain plug and install with new washer.
7. Refill with new engine oil.
Engine oil specification and viscosity:
Refer to MA-12, "
RECOMMENDED FLUIDS AND LUBRICANTS" .
Engine oil capacity (Approximate):
Unit: (US qt, Imp qt)
CAUTION:
The refill capacity depends on the engine oil temperature and drain time. Use these specifica-
tions for reference only.
Always use oil level gauge to determine the proper amount of engine oil in engine.
8. Warm up engine and check area around drain plug and oil filter for oil leakage.
9. Stop engine and wait for 15 minutes.
10. Check the engine oil level. Refer to LU-26, "
ENGINE OIL LEVEL" .

Removal and InstallationNBS004QE
REMOVAL
1. Remove front engine undercover with power tool.
2. Using the oil filter wrench (SST), remove the oil filter.
CAUTION:
Oil filter is provided with relief valve. Use Genuine Nissan
Oil Filter or equivalent.
Be careful not to get burned when engine and engine oil
may be hot.
When removing, prepare a shop cloth to absorb any
engine oil leakage or spillage.
Do not allow engine oil to adhere to drive belts.
Completely wipe off any engine oil that adhere to engine
and vehicle.
INSTALLATION
1. Remove foreign materials adhering to oil filter installation surface.
2. Apply new engine oil to the oil seal circumference of the new oil
filter.
3. Screw oil filter manually until it touches the installation surface,
then tighten it by 2/3 turn. Or tighten to specification.
INSPECTION AFTER INSTALLATION
1. Check the engine oil level. Refer to LU-26, "ENGINE OIL" .
2. Start engine, and check there is no leaks of engine oil.
3. Stop engine and wait for 15 minutes.
4. Check the engine oil level and adjust engine oil. Refer to LU-26, "
ENGINE OIL" .

Removal and InstallationNBS004QG
REMOVAL
1. Remove engine assembly from vehicle. Refer to EM-244, "ENGINE ASSEMBLY" .
2. Remove front cover. Refer to EM-203, "
TIMING CHAIN" .
3. Remove oil pump drive spacer.
Set bolts in the two bolt holes [M6 pitch 1.0 mm (0.04 in)] on
the front surface. Using suitable puller, pull oil pump drive
spacer off from crankshaft.
NOTE:
The dimension between the centers of the two bolt holes is 33
mm (1.30 in).
In the figure, a commercial steering puller is used.
4. Remove oil pump.
INSTALLATION
1. Install the oil pump.
2. Install oil pump drive spacer as follows:
a. Insert oil pump drive spacer according to the directions of crank-
shaft key and the two flat surfaces of oil pump inner rotor.
If the positional relationship does not allow the insertion,
rotate oil pump inner rotor with a finger to allow spacer.
b. After confirming that the position of each part is in correct condi-
tion to allow for spacer, force fit spacer by lightly tapping with
plastic hammer until it contacts and does not go further.

1. Remove oil pump cover.
2. Remove oil pump inner rotor and oil pump outer rotor from oil pump body.
3. After removing regulator valve plug, remove regulator valve spring and regulator valve.
INSPECTION AFTER DISASSEMBLY
Oil Pump Clearance
Measure the clearance with feeler gauge.
–Clearance between oil pump outer rotor and oil pump body
(Position 1)
–Tip clearance between oil pump inner rotor and oil pump outer
rotor (Position 2)
–If out of the standard, replace inner rotor and outor rotor.
Measure the clearance with feeler gauge and straightedge.
–Side clearance between oil pump inner rotor and oil pump body
(Position 3)
–Side clearance between oil pump outer rotor and oil pump body
(Position 4)
Calculate the clearance between oil pump inner rotor and oil pump body as follows:
OIL PUMP INNER ROTOR OUTER DIAMETER
–Measure the outer diameter of protruded portion of oil pump
inner rotor with micrometer. (Position 5)Standard : 0.114 - 0.200 mm (0.0045 - 0.0079 in)
Standard : Below 0.180 mm (0.0071 in)

OIL PUMP
Revision: 2006 January2006 M35/M45
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 the 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 the calculated value is 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 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: 2006 January2006 M35/M45
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-22
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-35

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-22
Engine oil levelCheck the level on the oil level gauge after parking the vehicle on a level spot
and turning off the engine.MA-18, MA-25
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-37
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-29
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.—
