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 check the engine oil level is within the range (A) shown in the figure.
3. If it is out of range, adjust it.
CAUTION:
Do not overfill the engine with oil.
OIL APPEARANCE
 Check the engine oil for a white milky appearance or excessive contamination.
 If the engine oil is milky, it is highly probable that 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
 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 yourself, as th e engine and engine oil may be hot.
 Put the A/T shift selector in the Park “P” position.
1. Check the engine oil level.
2. Remove front under cover.
3. Disconnect the oil pressure switch (1) harness connector.
4. Remove the oil pressure switch. CAUTION:
Do not drop or shock oil pressure switch.

5. Install the oil pressure gauge [SST: ST25051001 (J25695-1)] (A)and hose [SST: ST25052000 (J25695-2)] (B).
6. Start the engine and warm it up to normal operating temperature.
7. Check the engine oil pressure with engine running under no-load. Refer to LU-17, "
EngineOilPressure".
CAUTION:
If the difference is extreme, check the oil passages and oil pump for leaks and blockages.
8. 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 the specification. Use Genuine RTV Silicone Seal ant or equivalent. Refer to GI-22, "
Recommended Chemical Prod-
ucts and Sealants".
c. After warming up engine, make sure there is no leakage of engine oil with engine running.
DrainingINFOID:0000000006289617
WARNING:
 Be careful not to burn yourself, as th e engine and 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. Warm up the engine, and check for any oil leaks.
2. Stop the engine and wait for at least 10 minutes.
3. Remove drain plug and oil filler cap to drain the old oil.
RefillingINFOID:0000000006289618
1. Install drain plug with new washer. 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-10, "
Fluids and Lubricants".
CAUTION:
 The refill capacity depends on the engine oi l 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.
3. Warm up the engine and check area around drain plug and oil filter for engine oil leakage.
4. Stop the engine and wait for 10 minutes.
5. Check the engine oil level. Refer to LU-7, "
Inspection".

OIL FILTER
Removal and InstallationINFOID:0000000006289619
REMOVAL
1. Remove front under cover.
2. Drain engine oil. Refer to
LU-8, "
Draining".
3. Remove oil filter using oil filter wrench [SST: KV10115801 (J- 38956)].
WARNING:
Be careful not to burn yourself, as the engine and engine oil
may be hot.
CAUTION:
 The oil filter is equipped with a pressure relief valve.
 Use Genuine NISSAN oil filter or equivalent.
 When removing, prepare a s hop cloth to absorb any
engine oil leaks or spills.
 Do not allow engine oil to adhere to the drive belts.
 Completely wipe off any engine oil that adheres to the engine and the vehicle.
INSTALLATION
1. Remove foreign materials adhering to the oil filter seal mating surface.
2. Apply clean engine oil to the oil filter seal circumference of the
new oil filter as shown.
3. Screw on the oil filter manually until it touches the installation surface, then tighten it by 2/3 turn as shown. Or tighten to speci-
fication.
4. Refill engine with new engine oil. Refer to LU-8, "
Refilling".
5. Inspect engine for oil leaks. Refer to LU-7, "
Inspection".
6. Install front under cover.
InspectionINFOID:0000000006289620
INSPECTION AFTER INSTALLATION
1. Check engine oil level. Refer to LU-7, "Inspection".
2. Start engine and check for engine oil leaks.
3. Stop engine and wait for 10 minutes.

InspectionINFOID:0000000006289623
INSPECTION AFTER REMOVAL
Oil Cooler
Check oil cooler for cracks. Check oil cooler for clogging by blowing compressed air through engine coolant
inlet. If necessary, replace oil cooler assembly.
Relief Valve
Inspect relief valve for movement, cracks and breaks by pushing the ball. If replacement is necessary, remove
the valve by prying it out using a suitable tool. Install a new valve in place by tapping it in.
INSPECTION AFTER INSTALLATION
1. Check engine oil and engine coolant levels and add engine oil and engine coolant. Refer to LU-7, "Inspec-
tion" and CO-8, "Inspection".
2. Start the engine, and check for l eaks of engine oil or engine coolant.
