Inspection

INFOID:0000000010624154

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 check that 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 (upper and lower)
• Oil pan drain plug
• Oil pressure sensor
• Oil filter
• Oil cooler
• Intake valve timing control solenoid valve
• Exhaust valve timing control solenoid valve
• Front cover
• VTC cover
• Mating surface between cylinder block and cylinder head
• Mating surface between cylinder head and camshaft bracket
• Mating surface between camshaft bracket and rocker cover
• Mating surface between camshaft bracket and high pressure fuel pump
• Crankshaft oil seals (front and rear)

OIL PRESSURE CHECK

WARNING:

• Be careful not to get burned, as engine oil may be hot.
• When checking engine oil pressure, shift position should be “Parking position”, and apply parking

brake securely.

1.

Check engine oil level.

2.

Disconnect harness connector at oil pressure sensor 

, and

remove oil pressure sensor using a deep socket (commercial
service tool).

CAUTION:

Never drop or shock oil pressure switch.

3.

Install oil pressure gauge [SST: ST25051001] (A) and hose
[SST: ST25052000] (B).

4.

Start engine and warm it up to normal operating temperature.

5.

Check oil pressure with engine running under no-load.
NOTE:
When engine oil temperature is low, engine oil pressure becomes high.

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

6.

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.

Check engine oil level.

d.

After warming up engine, check that there is no leakage of engine oil with running engine.

Draining

INFOID:0000000010624155

WARNING:

• Be careful not to get burned, 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-22, "Inspec-

tion"

.

2.

Stop the engine and wait for 10 minutes.

3.

Loosen oil filler cap.

4.

Remove drain plug and then drain engine oil.

Refilling
