Check for oil leakage around the following areas:

• Oil  pan

• Oil pan drain plug

• Oil pressure switch

• Oil filter

• Oil cooler

• IVTC cover

• Front cover

• Mating surface between cylinder block and cylinder head

• Mating surface between cylinder head and rocker cover

• Crank oil seal (front and rear)

• For M/T models, put the gearshift lever in the Neutral "N" position. For CVT models, put the selector

lever in the Park “P” position.

1. Check the oil level. 
2. Remove undercover using power tool.
3. Disconnect oil pressure switch harness connector at the oil

pressure switch. Remove oil pressure switch and install Tools.

CAUTION:

Do not drop or shock oil pressure switch.

4. Start the engine and warm it up to normal operating temperature.

reference only. Always use the dipstick to determine when the proper amount of oil is in the

engine.

7. Warm up the engine and check around the oil pan drain plug and oil filter for oil leaks.
8. Stop engine and wait for 10 minutes.
9. Check the engine oil level using the dipstick.

CAUTION:

Do not overfill the engine oil.
