Inspection

INFOID:0000000009479889

OIL LEVEL

• Before starting the engine make sure the vehicle is parked on a flat

and level surface, then check the oil level. If the engine is already

running, turn it off and allow 10 minutes before checking. 

• Pull out oil level gauge and wipe clean.

• Insert oil level gauge.

• Check that the oil level is within the low (L) and high (H) range as

indicated on the dipstick.

• If the engine oil level is out of range, add oil as necessary. Refer to

MA-16, "FOR USA AND CANADA : Fluids and Lubricants"

.

CAUTION:

Do not overfill the engine with oil.

NOTE:

It is normal to add some oil between oil maintenance intervals or during the break-in period, depending on

the severity of the operating conditions.

OIL APPEARANCE

• Check the engine oil for a white milky appearance or excessive contamination.

• If the engine oil is milky, it is highly probable that it is contaminated with engine coolant. Repair or replace

damaged parts.

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 the engine and engine oil may be hot.

• Put the A/T shift selector in the Park (P) position (A/T models) or Neutral position (M/T models), and

apply parking brake securely.

1. Check engine oil level. Refer to 

LU-9, "Inspection"

.

2. Remove engine under cover. Refer to 

EXT-15, "Removal and Installation"

.

3. Disconnect the oil pressure switch harness connector.
4. Remove oil pressure switch using a suitable tool. Refer to 

EM-80, "Exploded View"

.

CAUTION:

Do not drop or shock oil pressure switch.

5. Install Tools.

6. Start the engine and warm it up to normal operating temperature.
7. Check the engine oil pressure with engine running under no-load. Refer to 

LU-16, "Standard and Limit"

.

CAUTION:

• If the difference between the test results and the specification is extreme, check the oil passages

and oil pump for leaks and blockages.

• The oil pump and balancer must be replaced as a unit. 

8. After the inspections, install oil pressure switch as follows:
a. Remove old liquid gasket adhering to oil pressure switch and the engine.
b. Apply liquid gasket and tighten oil pressure switch to the specification.

Use Genuine RTV Silicone Sealant or equivalent. Refer to 

GI-21, "Recommended Chemical Prod-

ucts and Sealants"

.

c.

After warming up engine, make sure there are no engine oil leaks.

9. Install engine under cover. Refer to 

EXT-15, "Removal and Installation"

WARNING:

• Be careful not to burn yourself, as the engine and 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 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 oil leaks
2. Stop the engine and wait for at least 10 minutes.
3. Remove the oil drain plug and oil filler cap to drain the old oil.
4. Install a new washer on the oil drain plug, then install the oil

drain plug in the oil pan.

CAUTION:

• Clean the drain plug and install with new washer.

• Do not reuse copper sealing washers.

5. Refill the engine with new specified engine oil.

CAUTION:

The refill capacity depends on the oil temperature and drain time. Use the "Refill oil capacity" val-

ues as a reference and check the oil level using the dipstick when filling the engine with oil.
