Engine Oil: Testing and Inspection

ENGINE OIL


Inspection


ENGINE OIL LEVEL

NOTE:
Park vehicle on a level surface, wait 10 minutes and check the engine oil level.
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, adjust it.

ENGINE OIL APPEARANCE
- Check engine oil for white milky or excessive contamination.
- If engine oil becomes 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 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 engine oil pressure check the transaxle should be in " Park position" (A/T models) and (CVT models) or "Neutral position" (M/T models), and apply the parking brake securely.
1. Check engine oil level.
2. Remove undercover using power tool.





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. Refer to .
If difference is extreme, check oil passage and oil pump for oil leaks.

NOTE:
When engine oil temperature is low, engine oil pressure becomes high.
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. Refer to Fluid Type Specifications.

Oil pressure switch : 14.7 N.m (1.5 kg-m, 11 ft-lb)

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