Inspection


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 the engine oil level is within the range (A) shown in the figure.
3. If it is out of range, adjust it.

NOTE:





When checking the engine oil level, insert oil level gauge (1) with its tip aligned with oil level gauge guide.

Arrow: Vehicle front


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 temperature sensor
- Oil filter
- Oil cooler
- Front cover
- Valve timing control cover
- Timing chain tensioner cover
- VVEL actuator sub assembly
- Crankshaft oil seals (front and rear)
- Camshaft position sensor and valve timing control solenoid valve (INT and EXH)
- Mating surface between cylinder head and VVEL ladder assembly
- Mating surface between VVEL ladder assembly and rocker cover
- Mating surface between cylinder block and cylinder head

OIL PRESSURE CHECK

WARNING:
- Be careful not to get burned, as engine oil may be hot.
- Oil pressure check should be done in "Parking position".
1. Check the engine oil level.
2. Remove engine undercover with power tool.





3. Disconnect harness connector at oil pressure switch (1), and remove oil pressure switch.

Arrow: Engine front


CAUTION:
Never drop or impact oil pressure switch.





4. Install the oil pressure gauge [SST: ST25051001 (J25695-1)] (A) and hose [SST: ST25052000 (J25695-2)] (B).
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 : Refer to "Engine Oil Pressure". [1][2]Engine Oil Pressure

If difference is extreme, check engine oil passage and oil pump for engine oil leakage.
7. After the inspections, install oil pressure switch as per the following:
a. Remove old liquid gasket adhering to oil pressure switch and the mating surface.
b. Apply liquid gasket and tighten oil pressure switch to the specification.
Use Genuine RTV Silicone Sealant or an equivalent. Recommended Chemical Products And Sealants.

Tightening torque : Refer to "Exploded View". Exploded View

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