Changing Engine OilBBS004WL
WARNING:

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-19, "
ENGINE OIL LEAKAGE" .
2. Stop engine and wait for 10 minutes.
3. Loosen oil filler cap and then remove drain plug.
4. Drain engine oil.
5. Install drain plug with new washer. Refer to EM-145, "
OIL PAN AND OIL STRAINER" .
CAUTION:
Be sure to clean drain plug and install with new washer.
6. Refill with new engine oil.
Engine oil specification and viscosity:
Refer to MA-14, "
RECOMMENDED FLUIDS AND LUBRICANTS" .
Engine oil capacity (Approximate):
Unit: (lmp qt)
CAUTION:

When filling engine oil, do not pull out oil level gauge.

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 the determine when the proper amount of engine oil is in the
engine.
NOTE:
The same quantity both VQ23DE and VQ35DE.
7. Warm up engine and check area around drain plug and oil filter for engine oil leakage.
8. Stop engine and wait for 10 minutes.
9. Check the engine oil level. Refer to LU-19, "
ENGINE OIL LEVEL" . Oil pan drain plug:
: 34.3 N·m (3.5 kg-m, 25 ft-lb)
Drain and refill With oil filter change 4.0 (3-1/2)

REMOVAL
1. Remove splash guard (RH).
2. Using oil filter wrench (SST), remove 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 adheres to engine
and vehicle.
NOTE:
Figure is shown as an example VQ35DE.
INSTALLATION
1. Remove foreign materials adhering to oil filter installation surface.
2. Apply new engine oil to the oil seal contact surface of new oil fil-
ter.
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-19, "ENGINE OIL" .
2. Start engine, and make sure there is no leaks of engine oil.
3. Stop engine and wait for 10 minutes.
4. Check the engine oil level and adjust engine oil. Refer to LU-19, "
ENGINE OIL" .

Refer to GI-10, "Components" for symbol marks in the figure.
WARNING:
Be careful not to get burn yourself, as engine oil and engine coolant may be hot.
REMOVAL
NOTE:
When removing oil cooler only, step 2 is unnecessary.
1. Remove splash guard (RH).
2. Drain engine coolant from radiator and cylinder block. Refer to CO-34, "
Changing Engine Coolant" and
EM-229, "
DISASSEMBLY" .
NOTE:
Perform this step when removing water pipes.
3. Remove oil filter. Refer to LU-22, "
OIL FILTER" .
CAUTION:
Do not spill engine oil on drive belts.
4. Disconnect water hoses from oil cooler.

When removing oil cooler only, pinching water hoses near oil cooler to prevent engine coolant spilling.

OIL COOLER (VQ35DE)

CAUTION:

Perform this step when engine is cold.

Do not spill engine coolant on drive belts.
5. Remove connector bolt, and remove oil cooler.
CAUTION:
Do not spill engine oil to rubber parts such as drive belts and engine mounting insulator.
6. Remove water pipes, as necessary.
INSPECTION AFTER REMOVAL
Oil Cooler
Check oil cooler for cracks. Check oil cooler for clogging by blowing through engine coolant inlet. If necessary,
replace oil cooler.
Relief Valve
Check relief valve for movement, cracks and breaks by pushing the ball. If replacement is necessary, remove
relief valve by prying it out with suitable tool. Install a new relief valve in place by tapping it.
INSTALLATION
Note the following, and install in the reverse order of removal.

Make sure that no foreign objects are adhering to the installation surfaces of oil cooler and oil pan (upper).

Align cutout on oil cooler with protrusion on oil pan (upper) side,
and tighten connector bolt.
INSPECTION AFTER INSTALLATION
1. Check the engine oil level and the engine coolant level, and add engine oil and engine coolant. Refer to
LU-19, "
ENGINE OIL" and CO-34, "ENGINE COOLANT" .
2. Start engine, and make sure that there is no leaks of engine oil or engine coolant.
3. Stop engine and wait for 10 minutes.
4. Check the engine oil level and the engine coolant level again. Refer to LU-19, "
ENGINE OIL" and CO-34,
"ENGINE COOLANT" .

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”)

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 BODY INNER DIAMETER
–Measure the inner diameter of oil pump body with inside
micrometer. (Position “5”)
OIL PUMP INNER ROTOR OUTER DIAMETER
–Measure the outer diameter of protruded portion of oil pump
inner rotor with micrometer. (Position “6”)
OIL PUMP INNER ROTOR 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.Standard:
VQ23DE : 0.120 - 0.195 mm (0.0047 - 0.0077 in)
VQ35DE : 0.114 - 0.260 mm (0.0045 - 0.0102 in)
Standard:

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

Install oil pump inner rotor with the groove faced to oil pump
