- Insert oil level gauge and check that the engine oil level is within
the range (A) shown.
- If engine oil is out of range, adjust it.
ENGINE OIL APPEARANCE
ENGINE OIL LEAKAGE
Check for engine oil leaks around the following areas.
- 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 and exhaust)
- Front cover
- Mating surface between cylinder head and camshaft bracket

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 “P”
(CVT models) or “N” (M/T models),
and apply parking brake securely.
- Check engine oil level.
- Disconnect harness connector at oil pressure sensor (1), and
remove oil pressure sensor using a suitable tool.
(2) : Starter motor
CAUTION:
Do not drop or shock oil pressure sensor.
- Install Tools (A) and (B).
Tool number (A) : ST25051001 (J-25695-1)
Tool number (B) : ST25052000 (J-25695-2)
- Start engine and warm it up to normal operating temperature.
- Check engine oil pressure with engine running under no-load.
NOTE:
When engine oil temperature is low, engine oil pressure becomes high.
Engine oil pressure : Refer to LU-17, "Oil Pressure".
CAUTION:
If difference is extreme, check oil passage and oil pump for oil leaks.
- After the inspections, install oil pressure sensor as follows:
- Remove old liquid gasket adhering to oil pressure sensor and engine.
- Apply liquid gasket and tighten oil pressure sensor to specification.
Use Genuine RTV Silicon Sealant or equivalent.
Tightening torque : Refer to EM-94, "Exploded View".
- Check engine oil level.
- After warming up engine, check that there are no leaks of engine oil
with engine running.
Draining
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.
- Warm up the engine, and check for engine oil leaks from engine
components. Refer to LU-7, "Inspection".
- Stop the engine and wait for 10 minutes.
- Loosen oil filler cap.
- Remove drain plug and then drain engine oil.
Refilling
- Install drain plug with new drain plug washer. Refer to EM-33, "Exploded
View".
CAUTION:
Be sure to clean drain plug and install with new drain plug washer.
Tightening torque : 34.3 NВ·m (3.5 kg-m, 25 ft-lb).
- Refill with new engine oil.
- Engine oil specification and viscosity: Refer to MA-11, "Engine Oil
Recommendation".
- • Engine oil capacity : Refer to LU-17, "Oil Capacity".
CAUTION:
- The refill capacity depends on the engine oil temperature and
drain time. Use these specifications
for reference only.
- Always use oil level gauge to determine the proper amount of
engine oil in the engine.
- Warm up engine and check area around drain plug and oil filter for
engine oil leaks.
- Stop engine and wait for 10 minutes.
- Check the engine oil level. Refer to LU-7, "Inspection".
