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.
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

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 lower cylinder block

Mating surface between cylinder block and cylinder head

Mating surface between cylinder head and rocker cover

Crankshaft oil seals (front and rear)
OIL PRESSURE CHECK
WARNING:

Be careful not to burn yourself, as engine oil may be hot.

Engine oil pressure check should be in “ Parking position” (A/T models) or “Neutral position” (M/T
models), and should apply parking brake securely.
1. Check engine oil level. Refer to LU-7, "
ENGINE OIL LEVEL" .
2. Remove RH undercover.

3. Disconnect harness connector at oil pressure switch, and
remove oil pressure switch using a deep socket (commercial
service tool).
4. Install oil pressure gauge and hose (special service tool).
5. Start engine and warm it up to normal operating temperature.
6. Check oil pressure with engine running under no-load.
NOTE:
When engine oil temperature is low, engine oil pressure becomes high.
Engine oil pressure [Engine oil temperature at 80°C (176°F)]
If difference is extreme, check oil passage and oil pump for oil leaks.
7. After the inspections, install oil pressure switch as follows:
a. Remove old liquid gasket adhering to oil pressure switch and engine.
b. Apply liquid gasket and tighten oil pressure switch to specification.
Use Genuine Thread Sealant or equivalent.
c. After warming up engine, make sure there is no leaks of engine oil with running engine.
Changing Engine OilEBS00KO4
WARNING:

Be careful not to burn yourself, as engine oil may be 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 oil leakage from engine components. Refer to LU-
7, "ENGINE OIL LEAKAGE" .
2. Stop engine and wait for 10 minutes.

Removal and InstallationEBS00KO8
WARNING:
Be careful not to get burned when engine and engine oil may be hot.
CAUTION:

When removing oil cooler and oil cooler bracket, prepare a shop cloth to absorb any engine oil
leakage or spillage.

Completely wipe off any engine oil that adhere to engine and vehicle.
REMOVAL
1. Remove RH front road wheel and tyre and RH undercover.
2. Drain engine coolant by removing water drain plug on cylinder block and radiator drain plug. Refer to EM-
89, "CYLINDER BLOCK" and CO-9, "Changing Engine Coolant" .
3. Disconnect water hoses from oil cooler.
4. Remove oil cooler and oil cooler bracket.
NOTE:
For reference when installing, put a mating mark on oil cooler and oil cooler bracket.
INSPECTION AFTER REMOVAL
Oil Cooler
Check oil cooler for cracks. Check oil cooler for clogging by blowing through engine coolant inlet. If necessary,
replace oil cooler assembly.
Relief Valve
Inspect relief valve for movement, cracks and breaks by pushing the ball. If replacement is necessary, remove
valve by prying it out with a suitable tool. Install a new valve in place by tapping it.
INSTALLATION
Installation is the reverse order of removal.
INSPECTION AFTER INSTALLATION
1. Check the engine oil level and the engine coolant level, and adjust engine oil and engine coolant. Refer to
LU-7, "
ENGINE OIL" and CO-9, "ENGINE COOLANT" .
