MAINTENANCE SERVICE

1. FUEL SYSTEM (TANK, PIPE LINE AND
CONNECTION, AND FUEL TANK FILLER TUBE
CAP) (CHECK FOR LEAKS)

M1001001600312

Check for damage or leakage in the fuel lines and connections.

2. FUEL HOSES (CHECK CONDITION)

M1001001700308

1. Inspect the surface of fuel hoses for heat and mechanical

damage. Hard and brittle rubber, cracking, tears, cuts,
abrasions and excessive swelling indicate deterioration of
the rubber.

2. If the fabric casing of the rubber hose is exposed by cracks

and abrasions in the fuel system, the hose should be
replaced.

3. AIR CLEANER FILTER (REPLACE)

M1001001800338

The air cleaner element will become dirty during use, reducing
its effectiveness. Replace it with a new one.
REPLACEMENT OF AIR CLEANER ELEMENT
1. Unclamp the air cleaner housing cover.
2. Remove the air cleaner element and install a new one.
3. When clamping the air cleaner housing cover in place, be

sure that the cover is completely closed.

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

M1001001900324

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

5. SPARK PLUGS (REPLACE)

M1001002000346

CAUTION

Iridium plugs are used. Use care not to damage the iridium
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 type

2. The new plugs should be checked for the proper gap.

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. INTAKE AND EXHAUST VALVE CLEARANCE
(INSPECT AND ADJUST)

M1001012900027

1. Before checks, check that the engine oil, starter and battery

are normal. Also, set the vehicle in the following condition:

• Engine coolant temperature: 80 − 95°C (176 − 203°F)

• Lights and all accessories: OFF

• Transaxle: P range

NOTE: Vehicles for Canada, the headlight, taillight, etc.
remain lit even when the lighting switch is in "OFF" position
but this is no problem for checks and adjustment.

2. Remove all of the ignition coils.
3. Remove the rocker cover.
4. Turn the crankshaft clockwise until the notch on the pulley is

lined up with "T" mark on the timing indicator.

5. Move the rocker arms on the No.1 and No.4 cylinders up

and down by hand to determine which cylinder has its piston
at the top dead center on the compression stroke.
If both intake and exhaust valve rocker arms have a valve
lash, the piston in the cylinder corresponding to these rocker
arms is at the top dead center on the compression stroke.

6. Valve clearance inspection and adjustment can be

performed on rocker arms indicated by white arrow mark
when the No.1 cylinder piston is at the top dead center on
the compression stroke, and on rocker arms indicated by
black arrow mark when the No.4 cylinder piston is at the top
dead center on the compression stroke.

7. Measure the valve clearance.

If the valve clearance is not as specified, loosen the rocker
arm lock nut and adjust the clearance using a thickness
gauge while turning the adjusting screw.

Standard value (hot engine):

<VEHICLES EXCEPT FOR CALIFORNIA EMISSION

REGULATION>

Intake valve: 0.20 mm (0.008 inch)
Exhaust valve: 0.32 mm (0.013 inch)

<VEHICLES FOR CALIFORNIA EMISSION REGULA-

TION>

Intake valve: 0.20 mm (0.008 inch)
Exhaust valve: 0.31 mm (0.012 inch)

8. While holding the adjusting screw with a screwdriver to

prevent it from turning, tighten the lock nut to the specified
torque.

Tightening torque: 9

± 1 N⋅m (80 ± 9 in-lb)

9. Turn the crankshaft through 360 degree angle to line up the

notch on the crankshaft pulley with the "T" mark on the
timing indicator.

10.Repeat steps (7) and (8) on other valves for clearance

adjustment.

11.Install the rocker cover.
12.Install the ignition coils.
