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 (A) shown in the figure.
3. If it is out of range, adjust it.
ENGINE OIL APPEARANCE
 Check engine oil for white turbidity or heavy contamination.
 If engine oil becomes turbid and 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 area.
 Oil pan (upper and lower)
 Oil pan drain plug
 Oil pressure switch
 Oil level sensor
 Oil filter
 Intake valve timing control solenoid valve
 Front cover
 Mating surface between cylinder head and camshaft bracket
 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 get burned, as engine oil may be hot.
 When checking engine oil pressure, shift position should be “Neutral”, and apply parking brake
securely.
1. Check engine oil level. Refer to LU-6, "
Inspection".

WARNING:
 Be careful not to burn yourself, as engine oil may be hot.
 For engine oil pressure check the transaxle should be in “Neutral position”, and apply the parking
brake securely.
1. Disconnect harness connector at oil pressure switch (1), and
remove oil pressure switch using a suitable tool.
