ENGINE OIL
WARNING:
• Be careful not to get burn your
self, as engine oil may be hot.
 Oil pressure check should be done in “Parking position”.
1. Check the engine oil level. Refer to "ENGINE OIL LEVEL".
2. Remove front engine undercover with power tool.
3. Disconnect harness connector at oil pressure sensor, and remove oil pressure sensor using deep socket (commercial ser-
vice tool).
CAUTION:
Do not drop or shock oil pressure switch.
4. Install the oil pressure gauge (SST) and hose (SST).
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.
Engine oil pressure [Engi ne oil temperature at 80 °C (176 °F)]
Unit: kPa (kg/cm2, psi)
If difference is extreme, check engine oil passage and oil pump for engine oil leaks.
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 RTV Silicone Seal ant or equivalent. Refer to GI-44, "
Recommended Chemical Prod-
uct and Sealant".

Changing Engine OilINFOID:0000000001325814
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 thorough ly with soap or hand cleaner as
soon as possible.
1. Remove front engine undercover with power tool.
2. Warm up the engine, and check for engine oil leakage from engine components. Refer to LU-5, "
Inspec-
tion".
3. Stop the engine and wait for 10 minutes.
4. Loosen oil filler cap and then remove drain plug.
5. Drain engine oil.
6. Install drain plug with new washer. Refer to EM-30, "
Component (2WD Models)".
CAUTION:
Be sure to clean drain plug and install with new washer.
7. Refill with new engine oil. Engine oil specificat ion and viscosity:
Refer to MA-9, "
Fluids and Lubricants".
Engine oil capacity (Approximate):
Unit: (US qt, lmp qt)
CAUTION:
 When filling engine oil, do not pull out oil level gauge.
 The refill capacity depends on the engine oi l 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.
8. Warm up the engine and check area around drain plug and oil filter for engine oil leakage.
9. Stop the engine and wait for 10 minutes.
10. Check the engine oil level. Refer to LU-5, "
Inspection".

WARNING:
Be careful not to get burn yourself, as en
gine oil and engine coolant may be hot.
NOTE:
When removing oil cooler only, step 2 is unnecessary.
1. Remove front engine undercover with power tool.
2. Drain engine coolant from radiator and cylinder block. Refer to CO-10, "
Changing Engine Coolant" and
EM-123, "
Disassembly and Assembly".
NOTE:
Perform this step when removing water pipes.
3. 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.
 Do not spill engine coolant on drive belts.
4. Using oil filter wrench [SST: KV10115801 (J38956)], remove oil filter. Refer to LU-8, "
Removal and Instal-
lation".
CAUTION:
Do not spill engine oil on drive belts.
5. Remove connector bolt, and remove oil cooler. CAUTION:

the engine oil level. If engine is already started, stop
it and allow 15 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 highl y probable that it is contaminated with engine coolant.
Repair or replace damaged parts.

Check for oil leakage around the following area.
Oil pan
 Oil pan drain plug
 Oil pressure switch
 Oil filter
 Oil cooler
 Intake valve timing control cover
 Intake valve timing control solenoid valve
 Front cover
 Chain tensioner cover
 Mating surface between cylinder block and cylinder head
