Engine Oil Pressure: Testing and Inspection

ENGINE OIL


Inspection


ENGINE OIL LEVEL

NOTE:
Before starting engine, park vehicle on a level surface 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 (A) as shown.
3. If it is out of range, add oil as necessary.

ENGINE OIL APPEARANCE
- Check engine oil for white milky appearance or excessive contamination.
- If engine oil becomes milky, 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 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 block and cylinder head
- Mating surface between cylinder head and rocker cover
- Crankshaft oil seals (front and rear)
- Oil filter (for intake valve timing control)

OIL PRESSURE CHECK

WARNING:
- Be careful not to burn yourself, as engine oil may be hot.
- For M/T models, put the shift selector in the Neutral "N" position and apply the parking brake securely. For CVT models, put the shift selector in the Park "P" position.
1. Check engine oil level.
2. Remove engine under cover. Service and Repair.





3. Disconnect harness connector at oil pressure switch (1), and remove oil pressure switch using a suitable tool.
- Oil pan (lower) (2)
- Arrow Indicates Front

CAUTION:
Do not drop or shock oil pressure switch.





4. Install oil pressure gauge and hose.






5. Start engine and warm it up to normal operating temperature.
6. Check oil pressure with engine running under no-load. [1][2]Engine Oil Pressure.

NOTE:
When engine oil temperature is low, engine oil pressure becomes high.
If difference is extreme, check oil passage and oil pump for oil leaks.
7. 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 Silicone RTV Sealant or equivalent. Recommended Chemical Products And Sealants.






c. Check engine oil level.
d. After warming up engine, make sure there are no leaks of engine oil with running engine.
