ENGINE OIL LEVEL
●Before starting the engine, put vehicle horizontally then check
the engine oil level. If the engine is already started, stop it and
allow 10 minutes before checking.
●Check that the engine oil level is within the range shown in the
figure.
●If it is out of range, adjust it.
ENGINE OIL APPEARANCE
●Check the engine oil for white turbidity or remarkable contamination.
●If the engine oil becomes turbid and white, it is highly probable that it is contaminated with engine coolant.
Find the cause and repair.
ENGINE OIL LEAKAGE
Check for engine oil leakage around the following area.
●Oil pan
●Oil pan drain plug
●Oil pressure switch
●Oil filter
●Oil cooler
●Intake valve timing control cover and intake valve timing control solenoid valve
●Front cover
●Mating surface between cylinder block and cylinder head
●Mating surface between cylinder head and rocker cover
●Crankshaft oil seal.
OIL PRESSURE CHECK
WARNING:
●Be careful not to burn yourself, as the engine oil is hot.
●Engine oil pressure check should be done in “ Parking
position” (A/T model) or “Neutral position” (M/T model).
1. Check engine oil level. Refer to LU-7, "
ENGINE OIL LEVEL" .
2. Remove the undercover.
3. Remove the oil pressure switch to connect the oil pressure
gauge.
4. After warming up the engine, check that oil pressure corre-
sponding to the engine speed is produced.
Engine oil pressure [Engine oil temperature at 80 °C (176 °F)]
5. After checking, install the oil pressure switch as follows.
a. Remove old sealant adhering to the switch and engine.
b. Apply thread sealant.
Use Genuine Liquid Gasket or equivalent.

WARNING:
●Be careful not to burn yourself, as the engine oil is 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.
2. Stop engine and wait for 10 minutes.
3. Remove drain plug and oil filler cap.
4. Drain engine oil.
●Install drain plug and refill with new engine oil.
Engine oil specifications and viscosity:
●API grade SG, SH, SJ or SL.
●ILSAC grade GF-I, GF-II or GF-III
●ACEA 96-A2
●Refer to MA-16, "RECOMMENDED FLUIDS AND LUBRICANTS" for further detail.
Engine oil capacity (Approximate):
Unit: (lmp qt)
CAUTION:
●Be sure to clean drain plug and install with new washer.
●The refill capacity depends on the engine oil temperature and drain time. Use these specifica-
tions for reference only.
●Always use the dipstick to the determine when the proper amount of engine oil is in the engine.
5. Warm up engine and check area around drain plug and oil filter for engine oil leakage.
6. Stop engine and wait for 10 minutes.
7. Check engine oil level. Refer to LU-7, "

REMOVAL
1. Open the oil filter installation/removal cover on the under cover.
2. Using an oil filter wrench, remove the oil filter.
CAUTION:
●The oil filter is provided with a relief valve.
Use genuine NISSAN oil filter or equivalent.
●Be careful not to get burned when the engine and engine
oil are hot.
●When removing, prepare a shop cloth to absorb any
engine oil leakage or spillage.
●Do not allow engine oil to adhere to the drive belts.
●Completely wipe off any engine oil that adhere to the
engine and the vehicle.
INSTALLATION
1. Remove foreign materials adhering to the oil filter installation surface.
2. Apply engine oil to the oil seal circumference of the new oil filter.
3. Screw the oil filter manually until it touches the installation sur-
face, then tighten it by 2/3 turn.
4. After warming up the engine, check for engine oil leakage.
5. Check engine oil level and add engine oil. Refer to LU-7,
"ENGINE OIL" .

●Measure clearance with feeler gauge and straightedge.
Side clearance between inner rotor and oil pump body (position

Side clearance between outer rotor and oil pump body (position
4).
●Calculate the clearance between inner rotor and oil pump body
as follows.
1. Measure the outer diameter of protruded portion of inner rotor
(Position 5).
2. Measure the inner diameter of oil pump body with inside
micrometer (Position 6).
(Clearance) = (Inner diameter of oil pump body) – (Outer diame-
ter of inner rotor)

WARNING:
Be careful not to get burned when the engine and engine oil are hot.
CAUTION:
●When removing oil cooler, prepare a shop cloth to absorb any engine oil leakage or spillage.
●Completely wipe off any engine oil that adhere to the engine and the vehicle.
REMOVAL
1. Remove front RH wheel and engine room right side cover.
2. Drain engine coolant by removing cylinder block drain plug and radiator drain cock. Refer to CO-9,
"Changing Engine Coolant" .
3. Paint a mating mark at the oil cooler and oil cooler bracket.
INSPECTION
Oil Cooler
Check oil cooler for cracks. Check oil cooler for clogging by blowing through engine coolant inlet. If necessary,
replace oil cooler assembly.
Oil Pressure Relief Valve
Inspect oil pressure relief valve for movement, cracks and breaks by pushing the ball. If replacement is neces-
sary, remove valve by prying it out with a suitable tool. Install a new valve in place by tapping it.
INSTALLATION
Installation is in the reverse order of removal.
●After warming up the engine, check for engine oil and engine coolant leakage and for engine oil level.
