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 make sure the engine oil level is within the range shown in the figure.
3. If it is out of range, adjust it.
NOTE:
When checking the engine oil level, insert oil level gauge with its
tip aligned with oil level gauge guide on cylinder head. (In figure,
air cleaner case and air duct are removed.)
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 areas:

Oil pans (lower and upper)

Oil pan drain plug

Oil pressure switch

Oil filter

Oil filter bracket (AWD models)

Oil cooler

Water pump cover

Chain tensioner cover

Intake valve timing control cover and intake valve timing control solenoid valve

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)

OIL PRESSURE CHECK
WARNING:

Be careful not to get burn yourself, as engine oil may be hot.

Oil pressure check should be done in “Parking position”.
1. Check the engine oil level. Refer to LU-7, "
ENGINE OIL LEVEL" .
2. Remove front engine undercover with power tool.
3. Disconnect harness connector at oil pressure sensor, and remove oil pressure sensor using deep socket (commercial ser-
vice tool).
CAUTION:
Do not drop or shock oil pressure switch.
4. Install the oil pressure gauge [SST] and hose [SST].
5. Start the engine and warm it up to normal operating temperature.
6. Check the engine oil pressure with engine running under no-load. NOTE:
When the engine oil temperature is low, the engine oil pressure becomes high.
Engine oil pressure [Engine oil temperature at 80 °C (176 °F)]
If difference is extreme, check engine oil passage and oil pump for engine oil leaks.
7. After the inspections, install oil pressure switch as follows:
