InspectionINFOID:0000000001381527
ENGINE OIL LEVEL
NOTE:
Before starting engine, put vehicle horizontally and check the engine oil level. If engine is already started, stop
it and allow 10 minutes before checking.
1. Pull out oil level gauge and wipe it clean.
2. Insert oil level gauge and make sure the engine oil level is within
the range (A) shown in the figure.
3. If it is out of range, adjust it.
ENGINE OIL APPEARANCE
 Check engine oil for white turbidity or heavy contamination.
 If engine oil becomes turbid and white, it is highly probable that it is contaminated with engine coolant.
Repair or replace damaged parts.
ENGINE OIL LEAKAGE
Check for engine oil leakage around the following area.
 Oil pan (upper and lower)
 Oil pan drain plug
 Oil pressure switch
 Oil level sensor
 Oil filter
 Intake valve timing control solenoid valve
 Front cover
 Mating surface between cylinder head and camshaft bracket
 Mating surface between cylinder block and cylinder head
 Mating surface between cylinder head and rocker cover
 Crankshaft oil seals (front and rear)
 Oil filter (for intake valve timing control)
OIL PRESSURE CHECK
WARNING:
 Be careful not to get burned, as engine oil may be hot.
 When checking engine oil pressure, shift position should be “Neutral”, and apply parking brake
securely.
1. Check engine oil level. Refer to LU-6, "
Inspection".

2. Disconnect harness connector at oil pressure switch (2), and
remove oil pressure switch (2) from the cylinder block (1) using
a deep socket (commercial service tool).
CAUTION:
Never drop or shock oil pressure switch.
3. Install oil pressure gauge and hose (SST).
4. Start engine and warm it up to normal operating temperature.
5. Check oil pressure with engine running under no-load.
NOTE:
When engine oil temperature is low, engine oil pressure becomes high.
If difference is extreme, check oil passage and oil pump for oil leaks.
6. After the inspections, install oil pressure switch as follows:
a. Remove old liquid gasket adhering to oil pressure switch and engine.
b. Apply liquid gasket and tighten oil pressure switch to specification.
Use Genuine Liquid Gasket or equivalent.
c. Check engine oil level. Refer to LU-6, "
Inspection".
d. After warming up engine, make sure there is no leaks of engine oil with running engine.
DrainingINFOID:0000000001381528
WARNING:
 Be careful not to get burned, 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 the engine, and check for engine oil leakage from engine components. Refer to LU-6, "
Inspec-
tion".
2. Stop the engine and wait for 10 minutes.
3. Loosen oil filler cap.
4. Remove drain plug and then drain engine oil.

Refilling
INFOID:0000000001381529
1. Install drain plug with new washer. Refer to EM-100, "Exploded View".
CAUTION:
Be sure to clean drain plug and install with new washer.
2. Refill with new engine oil.
Engine oil specification and viscosity: Refer to MA-19, "
Fluids and Lubricants".
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 the engine.
3. Warm up engine and check area around drain plug and oil filter for engine oil leakage.
4. Stop engine and wait for 10 minutes.
5. Check the engine oil level. Refer to LU-6, "
Inspection". Drain plug : Refer to EM-100, "
Exploded View".

REMOVAL
 Using oil filter wrench [SST: KV10115801] (A), 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.
 Completely wipe off any engine oil that adheres to engine
and vehicle.
INSTALLATION
1. Remove foreign materials adhering to the 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.
InspectionINFOID:0000000001381531
INSPECTION AFTER INSTALLATION
1. Check the engine oil level. Refer to LU-6, "Inspection".
2. Start the engine, and check there is no leak of engine oil.
3. Stop the engine and wait for 10 minutes.
4. Check the engine oil level, and adjust the level. Refer to LU-6, "
Inspection".
