ENGINE OIL LEVEL
NOTE:
Before starting engine, check engine oil level. If engine is already started, stop it and allow 10 minutes before
checking.
1. Put vehicle horizontally.
2. Pull out oil level gauge and wipe it clean.
3. Insert oil level gauge and make sure engine oil level is within the
range shown in the figure.
4. If it is out of range, adjust it.
NOTE:
When checking 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 is milky, it is highly probable that it is contaminated with engine coolant. Repair the broken
parts.
ENGINE OIL LEAKAGE
Check for engine oil leakage around the following areas:

Oil pan

Oil pan drain plug

Oil pressure switch

Oil filter

Oil cooler

Water pump cover

Chain tensioner cover

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

Mating surface between cylinder block and cylinder head

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 block and cylinder head

Crankshaft oil seal (front and rear)

OIL PRESSURE CHECK
WARNING:

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

Put selector lever in the Park “P” position.
1. Check engine oil level. Refer to LU-7, "
ENGINE OIL LEVEL" .
2. Remove front engine undercover with power tool.
3. Disconnect oil pressure switch harness connector.
4. Remove oil pressure switch.
5. Install oil pressure gauge (SST) and hose (SST).
6. Start engine and warm it up to normal operating temperature.
7. 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 [Engine oil temperature at 80 °C (176 °F)]
If difference is extreme, check engine oil passage and oil pump for engine oil leaks.
8. After the inspections, install oil pressure switch as follows:
a. Remove old liquid gasket adhering to oil pressure switch and the mating surface.
b. Apply liquid gasket and tighten oil pressure switch to specification.
