Precautions for Liquid GasketBBS0059K
LIQUID GASKET APPLICATION PROCEDURE
1. Remove old liquid gasket adhering to the liquid gasket application surface and the mating surface.
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 (SST).
Use Genuine Liquid Gasket or equivalent.
Within 5 minutes of liquid gasket application, install the mating
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 and engine coolant.

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
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”.
1. Check engine oil level. Refer to LU-7, "
ENGINE OIL LEVEL" .
2. Remove splash guard (RH).
3. Disconnect harness connector at oil pressure switch, and
remove oil pressure switch using deep socket (commercial ser-
vice tool).

ENGINE OIL
4. Install oil pressure gauge and hose (SST).
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 Liquid Gasket or equivalent.
c. After warming up engine, make sure there is no leaks of engine oil with running engine.

Changing Engine OilBBS0059Q
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 engine oil leakage from engine components. Refer
to LU-7, "
ENGINE OIL LEAKAGE" .
2. Stop 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-14, "
RECOMMENDED FLUIDS AND LUBRICANTS" .
Engine oil capacity (Approximate):
Unit: (lmp qt)
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 the determine when the proper amount of engine oil is in the
engine.
7. Warm up engine and check area around drain plug and oil filter for engine oil leakage.
8. Stop engine and wait for 10 minutes.
9. Check the engine oil level. Refer to LU-7, "
ENGINE OIL LEVEL" .

Removal and InstallationBBS0059R
REMOVAL
1. Remove splash guard (RH).
2. Using oil filter wrench (SST), 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.

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