2. FUEL HOSES (CHECK CONDITION)

M1001001700137

Make sure that the hoses do not come in contact with any heat
source or moving component which might cause heat damage
or mechanical wear.

3. AIR CLEANER ELEMENT (Replace)

M1001001800286

The air cleaner element will become dirty during use, reducing
its effect. Replace it with a new one.
REPLACEMENT OF AIR CLEANER ELEMENT
1. Loosen the clamp coupling the air intake hose and the air

cleaner housing cover, and separate the air intake hose.

2. Disconnect the volume airflow sensor connector.
3. Disconnect the air cleaner housing cover clips.
4. Remove the air cleaner housing cover and replace the air

cleaner element with a new one.

5. Clamp the clips and coupling, and then connect the volume

airflow sensor connector.

4. EVAPORATIVE EMISSION SYSTEM (CHECK
FOR LEAKS AND CLOGGING) - EXCEPT
EVAPORATIVE EMISSION CANISTER

M1001001900272

If the fuel-vapor vent line is clogged or damaged, the fuel vapor
mixture will escape into the atmosphere causing excessive
emissions. Disconnect the line at both ends, and blow it clean
with compressed air. Remove the fuel tank filler tube cap from
the filler tube and check to see if there is evidence that the
packing makes improper contact to the filler tube.

5. SPARK PLUGS (Replace)

M1001002000238

CAUTION

Iridium plugs are used. Use care not to damage the iridium
and platinum tips of the plugs. Do not adjust the spark
plug gap.
1. Spark plugs must spark properly to assure proper engine

performance and reduce exhaust emission level. Therefore,
they should be replaced periodically with new ones.

Spark plug gap: 0.7

− 0.8 mm (0.028 − 0.031 inch)

3. Install the spark plugs and tighten to 25

±5 N⋅m (18±4 ft-lb).

6. IGNITION CABLES (Replace)

M1001002100020

CAUTION

When disconnecting an ignition cable, be sure to hold the
cable boot. If the cable is disconnected by pulling on the
cable, an open circuit might result.
The ignition cables should be replaced periodically with new
ones. After replacing, make sure that the ignition cables are
routed properly and fully seated.

7. TIMING BELT (REPLACE)

CONDITION)

M1001002500318

Generator, Water Pump, Power Steering Pump
Drive Belt Tension Check and Adjustment

CAUTION

Perform the check after rotating the engine in the normal
direction (one revolution or more).
1. Check that the indicator mark of the auto-tensioner is

located between the marks shown as "A" on the tensioner
bracket.

2. If the mark is located out of the space "A," replace the drive

belt.

NOTE: Since the auto-tensioner is used, it is not necessary to
adjust the tension of the belt

Check of auto-tensioner

1. Run the engine at idling speed and then stop it to check

whether the drive belt is centered on the auto-tensioner
pulley.

2. Insert a1/2 inch breaker bar into the square hole on the drive

belt auto tensioner, and rotate it clockwise until the tensioner
touches the stopper.

3. Align hole B with hole A, and insert a 5.0 mm (0.20 inch)

Allen wrench to hold the tensioner. Then loosen the drive
belt, and then remove the drive belt auto tensioner.

4. Move the auto-tensioner right and left by using a 1/2 inch

breaker bar or similar tool to verify that it moves smoothly.

5. If some abnormality is found during the above mentioned

check (1) and (3), replace the auto-tensioner.

6. Install the drive belt auto tensioner with Allen wrench

inserted.

WARNING

Use care. Oil could be hot.

2. Remove the drain plug to allow the engine oil to drain.
3. Replace the drain plug gasket with a new one, and then

tighten the drain plug to the specified torque.
NOTE: Install the drain plug gasket so it faces in the direc-
tion shown in the illustration.

Tightening torque: 39

± 5 N⋅m (29 ± 3 ft-lb)

4. Pour new engine oil in through the oil filler tube.

Engine oil capacity: 4.3 dm

(4.5 quarts)

[excluding oil filter 0.3 dm

(0.32 quart), oil cooler 0.3

(0.32 quart)]

5. Start the engine and run it at idle for a few minutes.
6. Stop the engine and check to ensure that the engine oil level

is within the level range indicated on the dip stick.

10. ENGINE OIL FILTER (REPLACE)

M1001002700282

The quality of replacement filters varies considerably. Only high
quality filters should be used to assure most efficient service.
Genuine oil filters require that the filter is capable of withstand-
ing a pressure of 1,765 kPa (256 psi) are high quality filters and
are recommended as follows:
