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.
NOTE:
When checking oil level, insert oil level gauge (1) with its tip aligned with oil level gauge guide on cylinder
head.
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 oil leakage around the following areas:

Oil pans (lower and upper)

Oil pan drain plug

Oil pressure sensor

Oil filter

Valve timing control cover

Mating surface between cylinder head and rocker cover

Mating surface between front timing chain case and rear timing chain case

Mating surface between rear timing chain case and cylinder head

Mating surface between rear timing chain case and cylinder block

Mating surface between rear timing chain case and oil pan (upper)

Mating surface between cylinder block and cylinder head

Mating surface between lower cylinder block and cylinder block

Crankshaft oil seals (front and rear)

Camshaft position sensor and exhaust valve timing control position sensor.

OIL PRESSURE CHECK
WARNING:

Be careful not to burn yourself, as engine oil may be hot.

Oil pressure check should be done in “Neutral position” (M/T models) or “Parking position” (A/T
models).
1. Check the engine oil level. Refer to LU-6, "
ENGINE OIL LEVEL" .
2. Remove undercover with power tool.
3. Disconnect harness connector at oil pressure sensor, and
remove oil pressure sensor using deep socket (commercial ser-
vice tool).
CAUTION:
Do not drop or shock oil pressure sensor.
4. Install the oil pressure gauge (SST) and hose (SST).
5. Start the engine and warm it up to normal operating temperature.
6. Check the engine oil pressure with engine running under no-load.
NOTE:
When the engine oil temperature is low, the engine oil pressure becomes high.
Engine oil pressure [Engine oil temperature at 80 °C (176 °F)]
kPa (kg/cm2 , psi)
If difference is extreme, check engine oil passage and oil pump for engine oil leaks.
7. After the inspections, install oil pressure sensor as follows:
a. Remove old liquid gasket adhering to oil presser sensor and the mating surface.
b. Apply liquid gasket and tighten oil pressure sensor to the specification.
Use Genuine RTV Silicone Sealant or equivalent. Refer to GI-45, "
RECOMMENDED CHEMICAL
PRODUCTS AND SEALANTS" .
c. After warming up engine, make sure there is no leakage of engine oil with running engine.

ENGINE OIL
Revision: 2006 November2007 350Z

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 oil leakage from engine components. Refer to LU-
6, "ENGINE OIL LEAKAGE" .
2. Stop the 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-26, "
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-11, "
RECOMMENDED FLUIDS AND LUBRICANTS" .
Engine oil capacity (Approximate):
Unit: (US qt, 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 determine the proper amount of engine oil in the engine.
7. Warm up engine and check area around drain plug and oil filter for oil leakage.
8. Stop engine and wait for 10 minutes.
9. Check the engine oil level. Refer to LU-6, "
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 4.9 (5-1/8, 4-1/4)
Without oil filter change 4.6 (4-7/8, 4)

REMOVAL
WARNING:
Be careful not to get burned when engine and engine oil may be hot.
CAUTION:

Oil filter is provided with relief valve. Use Genuine NISSAN Oil Filter or equivalent.

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.
1. Remove undercover with power tool.
2. Using oil filter wrench [SST: KV10115801(J38956)] (B), remove
oil filter.
INSTALLATION
1. Remove foreign materials adhering to oil filter installation surface.
2. Apply engine oil to the oil seal contact surface of new oil filter.
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-6, "ENGINE OIL" .
2. Start engine, and check there is no leaks of engine oil.
3. Stop engine and wait for 10 minutes.
