Inspection
INFOID:0000000010783307
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 cooler
• Oil temperature sensor
• Oil pan (upper and lower)
• Oil pan drain plug
• Oil pressure sensor
• Oil filter
• Valve timing control cover
• Valve timing control solenoid valve (intake , exhaust and intermdeiate)
• Front cover
• Mating surface between cylinder head and camshaft bracket
• Mating surface between cylinder block and cylinder head
• Mating surface between camshaft bracket and rocker cover
• 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”, 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 sensor.

ENGINE OIL
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 sensor as follows:
a.
Remove old liquid gasket adhering to oil pressure sensor and engine.
b.
Apply liquid gasket and tighten oil pressure sensor 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:0000000010783308
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
2.
Stop the engine and wait for 10 minutes.
3.
Loosen oil filler cap.
4.
Remove drain plug
and then drain engine oil.
Refilling
INFOID:0000000010783309
1.
Install drain plug with new drain plug washer. Refer to
.
CAUTION:
Be sure to clean drain plug and install with new drain plug washer.

2.
Refill with new engine oil.
Engine oil specification and viscosity: Refer to
MA-23, "Fluids and Lubricants"
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 determine the proper amount of engine oil in the engine.
3.
Warm up engine and check area around drain plug and oil filter for engine oil leakage.
4.
Stop engine and wait for 10 minutes.
5.
Check the engine oil level. Refer to
Engine oil capacity
