Remove liquid gasket completely from the liquid gasket application surface, mounting bolts, and bolt
holes.
2. Wipe the liquid gasket application surface and the mating surface with white gasoline (lighting and heating
use) to remove adhering moisture, grease and foreign materials.
3. Attach liquid gasket tube to the tube presser (special service
tool).
Use Genuine Liquid Gasket or equivalent.

Within five minutes of liquid gasket application, install the mat-
ing component.

If liquid gasket protrudes, wipe it off immediately.

Do not retighten mounting bolts or nuts after the installation.

Wait 30 minutes or more after installation before refilling

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 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

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 lower cylinder block

Mating surface between cylinder block and cylinder head

Mating surface between cylinder head and rocker cover

Crankshaft oil seals (front and rear)
OIL PRESSURE CHECK
WARNING:

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

Engine oil pressure check should be in “ Parking position” (A/T models) or “Neutral position” (M/T
models), and should apply parking brake securely.
1. Check engine oil level. Refer to LU-7, "
ENGINE OIL LEVEL" .
2. Remove RH undercover.

3. Disconnect harness connector at oil pressure switch, and
remove oil pressure switch using a deep socket (commercial
service tool).
4. Install oil pressure gauge and hose (special service tool).
5. Start engine and warm it up to normal operating temperature.
6. Check oil pressure with engine running under no-load.
NOTE:
When engine oil temperature is low, engine oil pressure becomes high.
Engine oil pressure [Engine oil temperature at 80°C (176°F)]
If difference is extreme, check oil passage and oil pump for oil leaks.
7. 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 Thread Sealant or equivalent.
c. After warming up engine, make sure there is no leaks of engine oil with running engine.
Changing Engine OilEBS00KO4
WARNING:

Be careful not to burn yourself, 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 engine, put vehicle horizontally and check for oil leakage from engine components. Refer to LU-
7, "ENGINE OIL LEAKAGE" .
2. Stop engine and wait for 10 minutes.

Removal and InstallationEBS011TI
REMOVAL
1. Open oil filter installation/removal cover on RH undercover.
2. Using an oil filter wrench (special service tool), 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.

Do not allow engine oil to adhere to drive belt.

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.
INSPECTION AFTER INSTALLATION
1. Start engine, and make sure there is no leaks of engine oil.
2. Stop engine and wait for 10 minutes.
3. Check the engine oil level and add engine oil. Refer to LU-7, "
ENGINE OIL" .
