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 check 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 areas:
 Oil pans (lower and upper)
 Oil pan drain plug
 Oil pressure switch
 Oil filter
 Water pump cover
 Oil cooler
 Valve timing control covers (bank 1 and bank 2)
 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)
 Mating surface between cylinder block and cylinder head
 Crankshaft oil seals (front and rear)
 Camshaft position sensor (PHASE)
OIL PRESSURE CHECK
WARNING:
• Be careful not to get burn yourself, as engine oil may be hot.
 Oil pressure check should be done in “Parking position”.
1. Check the engine oil level. Refer to LU-7, "
Inspection".
2. Remove splash guard (RH). Refer to EXT-22, "
FENDER PROTECTOR : Exploded View".

3. Disconnect harness connector at oil pressure switch (2), and
remove oil pressure switch using deep socket (commercial ser-
vice tool).
CAUTION:
Never drop or shock oil pressure switch.
4. Install the oil pressure gauge [SST: ST25051001 (J25695-1)] (A)
and hose [SST: ST25052000 (J25695-2)] (B).
5. Start the engine and warm it up to normal operating temperature.
6. Check the engine oil pressure with engine running under no-load.
NOTE:
When the engine oil temperature is low, the engine oil pressure becomes high.
If difference is extreme, check engine oil passage and oil pump for engine oil leakage.
7. After the inspections, install oil pressure switch as follows:
a. Remove old liquid gasket adhering to oil pressure switch and the mating surface.
b. Apply liquid gasket and tighten oil pressure switch to the specification.
Use Genuine Liquid Gasket or equivalent.
c. After warming up engine, check there is no leakage of engine oil with running engine.
DrainingINFOID:0000000003793122
WARNING:
 Be careful not to get 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 the engine, and check for engine oil leakage from engine components. Refer to LU-7, "
Inspec-
tion".
2. Stop the engine and wait for 10 minutes.
3. Loosen oil filler cap.

RefillingINFOID:0000000003793123
1. Install drain plug with new washer. Refer to EM-38, "Exploded View".
CAUTION:
Be sure to clean drain plug and install with new washer.
2. Refill with new engine oil.
Engine oil specification and viscosity: Refer to MA-11, "
Fluids and Lubricants".
CAUTION:
 When filling engine oil, never pull out oil level gauge.
 The refill capacity depends on the engine oil temperature and drain time. Use these specifica-
tions for reference only.
 Always use oil level gauge to determine the proper amount of engine oil in engine.
3. Warm up the engine and check area around drain plug and oil filter for engine oil leakage.
4. Stop the engine and wait for 10 minutes.
5. Check the engine oil level. Refer to LU-7, "

OIL COOLER
4. Disconnect water hoses from oil cooler.
 When removing oil cooler only, pinching water hoses near oil cooler to prevent engine coolant from spill-
ing out.
 Remaining engine coolant in piping will come out. Use a tray to collect it.
CAUTION:
 Perform this step when the engine is cold.
 Never spill engine coolant on drive belt.
5. Remove connector bolt, and remove oil cooler.
CAUTION:
Never spill engine oil to rubber parts such as drive belt.
6. Remove water pipes, as necessary.
INSTALLATION
Note the following, and install in the reverse order of removal.
 Check that no foreign objects are adhering to the installation surfaces of oil cooler and oil pan (upper).
 Align cutout (B) on oil cooler (2) with protrusion (A) on oil pan
(upper) side, and tighten connector bolt (1).
InspectionINFOID:0000000003793129
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.
Relief Valve
Inspect relief valve for movement, cracks and breaks by pushing the ball. If replacement is necessary, remove
relief valve by prying it out with a suitable tool. Install a new relief valve in place by tapping it.
INSPECTION AFTER INSTALLATION
1. Check the engine oil level and the engine coolant level and add engine oil and engine coolant. Refer to
LU-7, "
