ENGINE OIL LEVEL
●Before starting the engine, put vehicle horizontally then check
the engine oil level. If the engine is already started, stop it and
allow 10 minutes before checking.
●Check that the engine oil level is within the range shown in the
figure.
●If it is out of range, adjust it.
ENGINE OIL APPEARANCE
●Check the engine oil for white turbidity or remarkable contamination.
●If the engine oil becomes turbid and white, it is highly probable that it is contaminated with engine coolant.
Find the cause and repair.
ENGINE OIL LEAKAGE
Check for engine oil leakage around the following area.
●Oil pan
●Oil pan drain plug
●Oil pressure switch
●Oil filter
●Oil cooler
●Intake valve timing control cover and 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.
OIL PRESSURE CHECK
WARNING:
●Be careful not to burn yourself, as the engine oil is hot.
●Engine oil pressure check should be done in “ Parking
position” (A/T model) or “Neutral position” (M/T model).
1. Check engine oil level. Refer to LU-7, "
ENGINE OIL LEVEL" .
2. Remove the undercover.
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 [Engine oil temperature at 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.

WARNING:
●Be careful not to burn yourself, as the engine oil is hot.
●Prolonged and repeated contact with used engine oil may
cause skin cancer. Try to avoid direct skin contact with
used engine oil. If skin contact is made, wash thoroughly
with soap or hand cleaner as soon as possible.
1. Warm up engine, put vehicle horizontally and check for engine
oil leakage from engine components.
2. Stop engine and wait for 10 minutes.
3. Remove drain plug and oil filler cap.
4. Drain engine oil.
●Install drain plug and refill with new engine oil.
Engine oil specifications and viscosity:
●API grade SG, SH, SJ or SL.
