(d) Align the knock pin and knock pin groove and install VVT-
i on the camshaft.
NOTICE:
Install it under the condition that the lock pin is operated
and lock at the maximum delay angle position.
(e) Apply the engine oil on the nut, the placing surface of
VVT-i and the screw portion.
HINT:
Be sure to apply the oil, otherwise the prescribed torque cannot
be obtained.
(f) Using a 46 mm socket wrench, install and torque a new
lock nut by turning it counterclockwise.
Torque: 150 N´m (1,530 kgf´cm, 110 ft´lbf)
NOTICE:
Must change the nuts to the new ones when to change
VVT-i.
The lock nut have LH threads.
Never use any tool other than the socket wrench,
otherwise that may result in deforming the cam angle
rotor portion.
3. REPLACE SPARK PLUG TUBE GASKETS
(a) Bend up the tab on the ventilation baffle plate which pre-

50°C (122°F) and ºHotº is from 50°C (122°F) to 100°C
(212°F).
1. INSPECT SPARK TEST
Check that the spark occurs.
(1) Remove the ignition coils (with igniters) (See page
IG-5).
(2) Remove the spark plugs.
(3) Install the spark plug to the ignition coil, and connect
the ignition coil connector.
(4) Ground the spark plug.
(5) See if spark occurs while engine is being cranked.
NOTICE:
To prevent gasoline from being injected from injectors dur-
ing this test, crank the engine for no more than 5 - 10 se-
conds at time.
If the spark does not occur, do the test as follows:

OIL AND FILTER
INSPECTION
1. CHECK ENGINE OIL QUALITY
Check the oil for deterioration, entry of water, discoloring or thin-
ning.
If the quality is visibly poor, replace the oil.
Oil grade:
API grade SJ, Energy-Conserving or ILSAC multi-
grade engine oil.
SAE 5W - 30 is the best choice for your vehicle, for
good fuel economy, and good starting in cold weath-
er.
2. CHECK ENGINE OIL LEVEL
After warm up the engine and then 5 minutes after the engine
stop, oil level should be between the low level and full level
marks on the dipstick.
If low, check for leakage and add oil up to the full level mark.
NOTICE:
Do not fill with engine oil above the full level mark.
3. REMOVE OIL PRESSURE SWITCH, AND INSTALL
OIL PRESSURE GAUGE
(a) Using SST, remove the oil pressure switch.
SST 09816-30010
(b) Install the oil pressure gauge.
4. WARM UP ENGINE
Allow the engine to warm up to normal operating temperature.
5. CHECK OIL PRESSURE
Oil pressure:
At idle29 kPa (0.3 kgf/cm2, 4.3 psi) or more
At 3,000 rpm294 - 539 kPa (3.0 - 5.5 kgf/cm2, 43 - 78 psi)

(a) Clean and install the oil drain plug with a new gasket.
Torque: 45 N´m (460 kgf´cm, 33 ft´lbf)
(b) Fill with fresh engine oil.

GENERAL MAINTENANCE
1. GENERAL NOTES
Maintenance items may vary from country to country. Check the owner's manual supplement in which
the maintenance schedule is shown.
Every service item in the periodic maintenance schedule must be performed.
Periodic maintenance service must be performed according to whichever interval in the periodic main-
tenance schedule occurs first, the odometer reading (miles) or the time interval (months).
Maintenance service after the last period should be performed at the same interval as before unless
otherwise noted.
Failure to do even one item an cause the engine to run poorly and increase exhaust emissions.
2. WINDSHIELD WASHER FLUID
Check that there is sufficient fluid in the tank.
3. ENGINE COOLANT LEVEL
Check that the coolant level is between the ºFULLº and ºLOWº lines on the see-through reservoir.
4. RADIATOR AND HOSES
(a) Check that the front of the radiator is clean and not blocked with leaves, dirt or bugs.
(b) Check the hoses for cracks, kinks, rot or loose connections.
5. BATTERY ELECTROLYTE LEVEL
Check that the electrolyte level of all battery cells is between the upper and lower level lines on the case.
6. BRAKE FLUID LEVEL
Check that the brake fluid level is near the upper level line on the see-through reservoirs.
7. ENGINE DRIVE BELTS
Check drive belt for fraying, cracks, wear or oiliness.
8. ENGINE OIL LEVEL
Check the level on the dipstick with the engine turned off.
9. POWER STEERING FLUID LEVEL
Check the level.
The level should be in the ºHOTº or ºCOLDº range depending on the fluid temperature.
10. AUTOMATIC TRANSMISSION FLUID LEVEL
(a) Park the vehicle on a level surface.
(b) With the engine idling and the parking brake applied, shift the selector into all positions from ºPº to ºLº,
and then shift into ºPº position.
(c) Pull out the dipstick and wipe off the fluid with a clean rag. Re-insert the dipstick and check that the
fluid level is in the ºHOTº range.
(d) Do this check with the fluid at normal driving temperature (70 - 80°C, 158 - 176°F).
HINT:
Wait until the engine cools down (approx. 30 min.) before checking the fluid level after extended driving at
high speeds, in hot weather, in heavy traffic or pulling a trailer.
11. EXHAUST SYSTEM
If any change in the sound of the exhaust or smell of the exhaust fumes is noticed, have the cause located
and corrected.
