BASIC INSPECTION
Engine Oil
1. Remove the engine oil level gauge and check the engine
oil level and oil condition.
2. Add or change the oil as necessary.
Coolant
Warning
l Never remove the radiator cap while the engine is
hot.
l Wrap a thick cloth around the cap before carefully
removing it.
1. Remove the coolant level gauge from the coolant reservoir.
2. Check that the coolant level is between the L and F marks
of the gauge.
3. Add coolant if necessary.
Battery
1. Check for corrosion on the terminals and for loose cable
connections. If necessary, clean the clamps and tighten
them firmly.
2. Check that the electrolyte level is between the UPPER LEV-
EL and LOWER LEVEL marks.
3. Add distilled water if necessary.
4. Check the specific gravity with a hydrometer.
Gravity: 1.27-l .29 (at 20% [68OF] )

Air Cleaner Element
Inspection
1. Check the air cleaner element for excessive dirt, damage,
or oil.
Caution
l Do not use compression air to clean the element.
2. Replace the element if necessary.
ADJUSTMENT
Preparation
1. Warm up the engine to normal operating temperature.
2. Turn all electric loads OFF.
3. Connect the
SST to the diagnosis connector.
4. Connect a timing light.
5. Connect a tachometer to the diagnosis connector
IG- ter-
minal as shown.
6. Set switch @to position 1.
7. Set TEST SW to SELF-TEST.
Note
l If the SST is not used, jump across the TEN termi-
nal and the GND terminal of the diagnosis con-
nector.
Ignition Timing
1. Perform “Preparation”. (Refer to above.)
2. Check if the timing mark (yellow) on the crankshaft pulley
and the mark on the timing belt cover are aligned.

3. If the marks are not aligned, loosen the distributor lock bolts,
and turn the distributor to make the adjustment.
4. Tighten the distributor lock bolts to the specified torque.
Tightening torque:
19-25 N#m (1.9-2.6 m-kg, 14-19 ft-lb)
5. Disconnect the SST.

5. Fuel filter
Assembly note
O-ring set
1. Use a new O-ring set. (O-ring, cap, and spacer)
2. Apply oil or fuel to the O-ring set before installing.
3. To confirm sealing of the O-ring, blow air through the main
pipe after assembling the fuel pump and fuel tank gauge
sender unit, and verify that no air flows past the O-ring. If
air flows through the pump, the check ball may be stuck.
Shake the fuel pump two or three times and recheck.
Fuel pump
1. After installing the fuel pump to the bracket, pull the pump
down so that it is tight against the bracket.

Rotor
1. Measure the resistance between the slip rings with an
ohmmeter.
Specification: 3.5-4.5Q [at 20°C (66OF)]
2. If not within specification, replace the rotor.
3. (1) Check continuity between each slip ring and the core
with an ohmmeter.
(2) Replace the rotor if there is continuity.
4. Check if the slip ring surface is rough. Use fine sandpaper
to repair it if necessary.
Stator
1. Check for continuity between the stator coil leads with an
ohmmeter.
2. Replace the stator it there is no continuity.
3. Check continuity between the stator coil leads and the core
with an ohmmeter.
4. Replace the stator if there is continuity.

Inspection
Spark test
1. Disconnect the high-tension lead from the distributor.
2. Hold it with insulated pliers 5-l
Omm (0.20-0.39 in) from
a ground.
3. Crank the engine and verify that a strong blue spark is
visible.
4. If there is no spark, disconnect the connector from the igni-
tion coil and check for voltage at the positive (+) terminal
of the connector with the ignition switch in the ON position.
Specification: Battery voltage
5. If there is no voltage, check the main fuse, ignition switch,
and wire harness.
Primary coil winding
1. Use an ohmmeter and measure resistance of the primary
coil winding. If not within specification, replace the coil.
Prlmary coil resistance: 0.81-0.99112 (at 2O*C [88*F])
Secondary coil winding
1. Use an ohmmeter and measure resistance of the secon-
dary coil winding. If not within specification replace the coil.
Secondary coil resistance: lo-18 kQ (at 20°C [68*F])
Insulation of case
1. Use a 500V megger tester to measure the insulation resis-
tance between each terminal and the case.
