OIL LEVEL
• Before starting the engine make sure the vehicle is parked on a flatand level surface, then check the oil level. If the engine is already
running, turn it off and allow 10 minutes before checking.
• Check that the oil level is within the low (L) and high (H) range as indicated on the dipstick.
• If the engine oil level is out of range, add oil as necessary. Refer to
MA-12, "
Fluids and Lubricants".
OIL APPEARANCE
• Check the engine oil for a white milky appearance or excessive contamination.
• If the engine oil is milky, it is highly probable that it is contaminated with engine coolant. Repair the broken
parts.
OIL LEAKAGE
Check for oil leakage around the following areas:
•Oil pan
• Oil pan drain plug
• Oil pressure switch
• Oil filter
• Oil cooler
• Intake valve timing control cover
• 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 seal (front and rear)
OIL PRESSURE CHECK
WARNING:
• Be careful not to burn yoursel f, as engine oil may be hot.
• Put the A/T shift selector in the Park “P” position.
1. Check the engine oil level. Refer to LU-8, "
Inspection".
2. Remove engine front undercover using power tool.
3. Disconnect the oil pressure switch harness connector.
4. Remove the oil pressure switch (A).
