ENGINE OIL
InspectionINFOID:0000000009461048
OIL LEVEL
NOTE:
• Before starting the engine, check the oil level. If the engine is already started, stop it and a llow 10 minutes before checking.
• Check that the oil level is within the range as indicated on the oil level gauge.
• If it is out of range, add oil as necessary.
ENGINE OIL APPEARANCE
• Check engine oil for white milky appearance or excessive contamination.
• If engine oil becomes milky, it is highly probable t hat it is contaminated with engine coolant. Repair or
replace damaged parts.
OIL LEAKAGE
Check for oil leakage around the following areas:
•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 (front and rear)
OIL PRESSURE CHECK
WARNING:
• Be careful not to burn yoursel f, as engine oil may be hot.
• Put the CVT shift selector in the Park “P” position.
1. Check the oil level.
2. Remove fender protector side cover (RH). Refer to EXT-26, "FENDER PROTECTOR : Exploded View"
.
3. Disconnect oil pressure switch harness connector at the oil pressure switch. Remove oil pressure switch and install Tools.
CAUTION:
Do not drop or shock oil pressure switch.
4. Start the engine and warm it up to normal operating temperature.
5. Check oil pressure with engine running under no-load, using Tool. NOTE:
• When engine oil temperature is low, engine oil pressure becomes high.

ENGINE OIL
• If difference is extreme, check oil passage and oil pump for oil leaks.
6. After the inspections, install the oil pressure switch as follows:
a. Remove the old sealant adhering to oil pressure switch and engine.
b. Apply thread sealant and tighten the oil pressure switch to specification. Use Genuine High Performance Th read Sealant, or equivalent.
c. After warming up engine, make sure there are no engine oil leaks.
7. Install fender protector side cover (RH). Refer to EXT-16, "Exploded View"
.
Changing Engine OilINFOID:0000000009461049
WARNING:
• Be careful not to burn yourself, as the 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 oil. If skin contact is made, wash thoroughly with soap or hand cleaner as soon as
possible.
1. Position the vehicle so it is level on the hoist.
2. Warm up the engine and check for oil leaks from the engine.
3. Stop engine and wait for 10 minutes.
4. Remove the oil pan drain plug (1) and oil filler cap.
5. Drain the engine oil.
6. Install the oil pan drain plug (1) with a new washer and refill the engine with new engine oil.
CAUTION:
• Be sure to clean the oil pan drain plug and install with a new washer.
• The refill capacity depends on the oil temper ature and drain time. Use these specifications for
reference only. Always use the dipstick to determine when the proper amount of oil is in the
engine.
7. Warm up the engine and check around the oil pan drain plug and oil filter for oil leaks.
8. Stop engine and wait for 10 minutes.
9. Check the engine oil level using the oil level gauge. CAUTION:
Do not overfill the engine with engine oil. Engine oil pressure :

REMOVAL
1. Drain engine oil. Refer to
LU-26, "Changing Engine Oil".
2. Remove the fender protector side cover (RH). Refer to EXT-26, "FENDER PROTECTOR : Exploded
View".
3. Remove the oil filter using Tool (A) as shown.
WARNING:
• Be careful not to get burned , the engine and engine oil
may be hot.
CAUTION:
• When removing, prepare a shop cloth to absorb any oil leakage or spillage.
• Do not allow engine oil to adhere to the drive belts.
• Completely wipe off any oil th at adheres to the engine and
the vehicle.
• The oil filter has a built in pressure relief valve. Use a Gen- uine NISSAN oil filter or equivalent
INSTALLATION
1. Remove foreign materials adhering to the oil filter installation surface.
2. Apply clean engine oil to the oil seal contact surface of the new oil filter.Tool number : KV10115801 (J-38956)

INSPECTION AFTER DISASSEMBLY
Clearance of Oil Pump Parts
• Measure clearance with feeler gauge.
• Clearance between outer rotor and oil pump body (position 1).
• Tip clearance between inner rotor and outer rotor (position 2).
• Measure clearance with feeler gauge and straightedge.
• Side clearance between inner rotor and oil pump body (position 3).
• 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 A).
2. Measure the inner diameter of oil pump body with inside micrometer (position B).
(clearance 5) = (inner diameter of oil pump body B) – (outer
diameter of inner rotor A)
3. If out of specifications , replace oil pump assembly.
