OIL LEVEL

NOTE:
Before starting engine, put vehicle horizontally and check the 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 oil level is within the
range shown in the figure.

3.

If it is out of range, adjust it.

NOTE:
When checking oil level, insert oil level gauge with its tip aligned with
oil level gauge guide on cylinder head. (In the figure, air cleaner case
and air duct are removed.)

OIL APPEARANCE

●

Check the engine oil for white turbidity or heavy contamination.

●

If the engine oil becomes turbid and white, it is highly probable that it is contaminated with engine coolant.
Repair or replace damaged parts.

OIL LEAKAGE

Check for oil leakage around the following areas:

●

Oil pans (lower and upper)

●

Oil pan drain plug

●

Oil pressure switch

●

Oil filter

●

Oil cooler

●

Water pump cover

●

Chain tensioner cover

●

Intake valve timing control solenoid valve

●

Intake valve timing control cover (A/T models)

●

Valve timing control cover (M/T models)

●

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

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 oil level. Refer to 

LU-7, "OIL LEVEL"

 .

2.

Remove undercover with power tool.

3.

Disconnect oil pressure switch harness connector.

4.

Remove oil pressure switch.

5.

Install oil pressure gauge and hose (SST).

6.

Start engine and warm it up to normal operating temperature.

7.

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)]

Unit: kPa (kg/cm

2

 , psi)

If difference is extreme, check oil passage and oil pump for oil leaks.

8.

After the inspections, install oil pressure switch as follows:

a.

Remove the old liquid gasket adhering to oil pressure switch and engine.

b.

Apply liquid gasket and tighten oil pressure switch to specification.
Use Genuine RTV Silicone Sealant or equivalent. Refer to 

GI-46, "RECOMMENDED CHEMICAL

PRODUCTS AND SEALANTS"

 .

c.

After warming up engine, make sure there is no leakage of engine oil with running engine.

WARNING:

●

Be careful not to burn yourself, as the 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, "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-29, "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-10, "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.

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
