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.
NOTE:
When checking the engine oil level, insert oil level gauge with its
tip aligned with oil level gauge guide on cylinder head. (In figure,
air cleaner case and air duct are removed.)
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 areas:
Oil pans (lower and upper)
Oil pan drain plug
Oil pressure switch
Oil filter
Oil filter bracket (AWD models)
Oil cooler
Water pump cover
Chain tensioner cover
Intake valve timing control cover and intake valve timing control solenoid valve
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

OIL PRESSURE CHECK
WAR NING :
Be careful not to get burn yourself, as engine oil may be hot.
Oil pressure check should be done in “Parking position”.
1. Check the engine oil level. Refer to LU-7, "
ENGINE OIL LEVEL" .
2. Remove front engine undercover with power tool.
3. Disconnect harness connector at oil pressure switch, and
remove oil pressure switch using deep socket (commercial ser-
vice tool).
CAUTION:
Do not drop or shock oil pressure switch.
Remove the oil pressure switch using a 26 mm (1.02 in) box
wrench. (AWD models)
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)]
If difference is extreme, check engine oil passage and oil pump for engine oil leaks.
7. After the inspections, install oil pressure switch as follows:

Engine speed (rpm)
Approximate discharge pressure [kPa (kg/cm2 , psi)]
Idle speed More than 98 (1.0, 14)

a. Remove old liquid gasket adhering to oil pressure switch and the mating surface.
b. Apply liquid gasket and tighten oil pressure switch to the specification.
Use Genuine RTV Silicone Sealant or equivalent. Refer to GI-48, "
RECOMMENDED CHEMICAL
PRODUCTS AND SEALANTS" .
c. After warming up engine, make sure there is no leakage of engine oil with running engine.
Changing Engine OilNBS004PX
WAR NING :
Be careful not to get 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 the engine, and check for engine oil leakage from engine components. Refer to LU-7, "
ENGINE
OIL LEAKAGE" .
2. Stop the engine and wait for 10 minutes.
3. Loosen oil filler cap.
4. Remove mounting bolts, and then pull down the rear of front
engine undercover (1) and secure it using clip.
5. Remove drain plug (2) and then drain engine oil.
6. Install drain plug with new washer. Refer to EM-29, "
OIL PAN AND OIL STRAINER" .
CAUTION:
Be sure to clean drain plug and install with new washer.
7. Refill with new engine oil.
Engine oil specification and viscosity:
Refer to MA-12, "
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 engine.
8. Warm up the engine and check area around drain plug and oil filter for engine oil leakage.
9. Stop the engine and wait for 10 minutes.
10. Check the engine oil level. Refer to LU-7, "
ENGINE OIL LEVEL" . Oil pressure switch:
