Changing Engine Oil
WARNING:
IBe careful not to burn yourself, as the engine oil is hot.
I Prolonged and repeated contact with used engine oil may
cause skin cancer; try to avoid direct skin contact with
used oil. If skin contact is made, wash thoroughly with
soap or hand cleaner as soon as possible.
1. Warm up engine, and check for oil leakage from engine com- ponents.
2. Stop engine.
3. Remove dipstick, oil filler cap and drain plug.
4. Drain oil.
5. Install drain plug.
CAUTION:
I Be sure to clean drain plug and install with new washer.
Drain plug:
: 29-39N ×m(3.0 - 4.0 kg-m, 21 - 29 ft-lb)
6. Fill slowly with new oil whilst not exceeding the maximum level.
Oil specification and viscosity:
I See ªRECOMMENDED FLUIDS AND LUBRICANTSº (MA-
17).
Oil capacity (Approximately):
Unit: (Imp qt)
Drain and refill
With oil filter change 6.2 (5-1/2)
Without oil filter change 5.5 (4-7/8)
CAUTION:
IThe refill capacity depends on the oil temperature and
drain time. Use these specifications for reference only.
Always use the dipstick to determine when the proper
amount of oil is in the engine.
7. Install dipstick and filler cap.
8. Start engine. Check area around drain plug and oil filter for any sign of oil leakage.
9. Run engine for a few minutes, then turn it off. After several minutes check oil level again.
10. If necessary, add oil whilst not exceeding the maximum level.
Changing Oil Filter
1. Remove oil filter with a suitable wrench.
WARNING:
Be careful not to burn yourself as engine and oil is hot.

Removal
WATER PUMP, ALTERNATOR AND AIR CONDITIONER
BELT
1. Remove radiator shroud.
2. Contract and hold the auto tensioner using the following proce-dure.
a. Securely hold the 19 mm (0.75 in) hexagonal portion A of auto tensioner with a closed wrench.
I Preferably use a tool with a handhold of 500 mm (19.69 in) or
more in length.
I No bolts or nuts are required to be loosened during the opera-
tion.
b. Turn the hexagonal portion A in the direction shown by the arrow to contract the damper unit of the auto tensioner.
CAUTION:
I Because the tensioner has a high tension, it shall be
securely held and turned with a closed wrench.
I Because the hexagonal portion A of the tensioner is made
of aluminum and may be damaged by sudden input, turn
it slowly according to the contraction of the damper unit.
3. Remove the belt from the alternator pulley first, and then remove it from the other pulleys.
I If the tensioner is not held firmly, your finger may get caught
between the belt and the pulleys. Confirm the holding of the
tensioner, and then hold the belt side in the place away from
the pulleys to attach or remove the belt, paying attention to
prevent your finger from being caught.
CAUTION:
I When handling the belt, pay attention to prevent the oil or
coolant from adhering to the belt.
I Do not distort or bend the belt intensively.
Installation
IInstall the belt in the reverse order of removal.
I After installation of the belt, confirm that the belt engages the
pulleys securely.
I Depending on the engagement between the belt and the idler
pulley, noise (belt noise) may be heard when the engine is
started just after installation. This noise will stop with time.
Changing Engine Oil
WARNING:
IBe careful not to burn yourself, as engine oil is hot.
I Prolonged and repeated contact with used engine oil may
cause skin cancer; try to avoid direct skin contact with
used oil. If skin contact is made, wash thoroughly with
soap or hand cleaner as soon as possible.
1. Warm up engine, and check for oil leakage from engine com- ponents.
2. Remove drain plug and oil filler cap.

5. While referring to the figure, measure the valve clearance in thecircled area of the table below.

When the No. 4
cylinder is in the
TDC qq qq
6. If the valve clearance is outside the specification, adjust as fol-
lows.
Adjustments
IRemove the adjusting shim for parts which are outside the
specified valve clearance.
1. Remove the spill tube.
2. Extract the engine oil on the upper side of the cylinder head (for the air gun used in step 7).
3. Rotate the crankshaft to face the cam for adjusting shims that are to be removed upward.
4. Grip the camshaft with camshaft pliers (SST), the using the camshaft as a support point, push the adjusting shim downward
to compress the valve spring.
CAUTION:
Do not damage the camshaft, cylinder head, or the outer cir-
cumference of the valve lifter.
5. With the valve spring in a compressed state, remove the cam- shaft pliers (SST) by securely setting the outer circumference
of the valve lifter with the end of the lifter stopper (SST).
I Hold the lifter stopper by hand until the shim is removed.
CAUTION:
Do not retrieve the camshaft pliers forcefully, as the camshaft
will be damaged.
6. Move the rounded hole of the adjusting shim to the front with a very thin screwdriver.
I When the adjusting shim on the valve lifter will not rotate
smoothly, restart from step 4 with the end of the lifter stopper
(SST) touching the adjusting shim.
7. Remove the adjusting shim from the valve lifter by blowing air through the rounded hole of the shim with an air gun.
CAUTION:
To prevent any remaining oil from being blown around, thor-
oughly wipe the area clean and wear protective goggles.
