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 that the engine oil level is within the range (A) 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 pan (upper and lower)
- Oil pan drain plug
- Oil pressure switch
- Oil filter
- Intake valve timing control solenoid valve
- Front cover
- Mating surface between cylinder head and camshaft bracket
- Mating surface between cylinder block and cylinder head
- Mating surface between cylinder head 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 position", and apply parking brake securely.
1. Check engine oil level. Inspection.










2. Disconnect harness connector at oil pressure switch (1), and remove oil pressure switch using a deep socket (commercial service tool).

CAUTION:
Never drop or shock oil pressure switch.





3. Install oil pressure gauge [SST: ST25051001 (J-25695-1)] (A) and hose [SST: ST25052000 (J-25695-2)] (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.

Engine oil pressure : Specifications

If difference is extreme, check oil passage and oil pump for oil leakage.
6. After the inspections, install oil pressure switch as follows:
a. Remove old liquid gasket adhering to oil pressure switch and engine.
b. Apply liquid gasket and tighten oil pressure switch to specification.
Use Genuine RTV Silicon Sealant or equivalent. Fluid Type Specifications.

c. Check engine oil level. Inspection.
d. After warming up engine, check that there is no leakage of engine oil with running engine.
