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).

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, "

OIL PRESSURE CHECK
WARNING:

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

Oil pressure check should be done in “Parking position”.
1. Check engine oil level. Refer to LU-19, "
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).
NOTE:
Figure is shown as an example of VQ35DE.
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 leakage of engine oil with running engine.
