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 make sure the engine oil level is within the range shown in the figure.
3. If it is out of range, adjust it.
NOTE:
When checking the engine oil level, insert oil level gauge with its
tip aligned with oil level gauge guide on cylinder head. (In figure,
air cleaner case and air duct are removed.)
ENGINE OIL APPEARANCE
 Check engine oil for white turbidity or heavy contamination.
 If engine oil becomes turbid and white, it is highl y 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 pans (lower and upper)
 Oil pan drain plug
 Oil pressure switch
 Oil filter
 Oil filter bracket (AWD models)
 Oil cooler
 Water pump cover
 Chain tensioner cover
 Intake valve timing control cover and intake valve timing control solenoid valve
 Mating surface between cylinder head and rocker cover
 Mating surface between front timing chain case and rear timing chain case
 Mating surface between rear timing chain case and cylinder head
 Mating surface between rear timing chain case and cylinder block
 Mating surface between rear timing chain case and oil pan (upper)
