OIL LEVEL AND MUDDINESS
lBefore starting the engine, check the oil level. If the engine is
already started, stop it and allow 10 minutes before checking.
lCheck that the oil level is within the range shown in the figure.
lIf it is out of range, adjust it.
lCheck the oil for white turbidity or remarkable contamination.
lIf the oil becomes turbid and white, it is highly probable that it is
contaminated with coolant. Find the cause and repair.
OIL LEAKAGE
Check for oil leakage around the following area.
lOil pan
lOil pan drain plug
lOil pressure switch
lOil filter
lIntake valve timing control cover
lFront cover
lMating surface between cylinder block and cylinder head
lMating surface between cylinder head and rocker cover
lCrankshaft oil seal.
OIL PRESSURE CHECK
WA RN ING:
lBe careful not to burn yourself, as the engine oil is hot.
lOil pressure check should be done in “ Parking position”.
1. Check the oil level.
2. Remove the under cover.
3. Remove the oil pressure switch to connect the oil pressure
gauge.
4. After warming up the engine, check that oil pressure corre-
sponding to the engine speed is produced.
Engine oil pressure [Oil temperature is 80°C (176°F)]
5. After checking, install the oil pressure switch as follows.
a. Remove old sealant adhering to the switch and engine.
b. Apply thread sealant.
Use Genuine Liquid Gasket or equivalent.

WAR NIN G:
lBe careful not to burn yourself, as the engine oil is hot.
lProlonged and repeated contact with used engine oil may
cause skin cancer: try to avoid direct skin contact with
used oil. If skin contact is made, wash thoroughly with soap
or hand cleaner as soon as possible.
1. Warm up engine, and check for oil leakage from engine compo-
nents.
2. Stop engine and wait for 10 minutes.
3. Remove drain plug and oil filler cap.
4. Drain oil and refill with new engine oil.
Oil specification and viscosity:
lAPI grade SG, SH or SJ.
lILSAC grade GF-I or GF-II
lRefer toMA-17, "RECOMMENDED FLUIDS AND LUBRICANTS".
Oil capacity (Approximate):
CAUTION:
lBe sure to clean drain plug and install with new washer.
lThe refill capacity depends on the oil temperature and drain time. Use these specifications for ref-
erence only.
Always use the dipstick to the determine when the proper amount of oil is in the engine.
5. Warm up engine and check area around drain plug and oil filter for oil leakage.
6. Stop engine and wait for 10 minutes.
7. Check oil level.

REMOVAL
1. Open the oil filter installation/removal cover on the under cover.
2. Using an oil filter wrench, remove the oil filter.
CAUTION:
lBe careful not to get burned when the engine and engine oil
are hot.
lWhen removing, prepare a shop cloth to absorb any oil
leakage or spillage.
lDo not allow engine oil to adhere to the drive belts.
lCompletely wipe off any oil that adhere to the engine and
the vehicle.
INSTALLATION
1. Remove foreign materials adhering to the oil filter installation surface.
2. Apply engine oil to the oil seal circumference of the new oil filter.
3. Screw the oil filter manually until it touches the installation sur-
face, then tighten it by 2/3 turn.
4. After warming up the engine, check for engine oil leakage.
5. Check oil level and add engine oil. Refer toLU-7, "
