G FUNDAMENTAL PROCEDURES
DISASSEMBLY
1. Inspection of parts
Each part when removed should be carefully inspect-
ed for malfunctioning, deformation, damage, and
other problems.
2. Arrangement of parts
All disassembled parts should be carefully arranged
for reassembly.
Be sure to separate or otherwise identify the parts to
be replaced from those that will be reused.
3. Cleaning parts for reuse
All parts to be reused should be carefully and
thoroughly cleaned in the appropriate method.
REASSEMBLY
Standard values, such as torques and certain adjust-
ments, must be strictly observed in the reassembly
of all parts.
If removed, these parts should be replaced with new
ones:
1. Oil seals
2. Gasket
3. O-rings
4. Lock washers
5. Cotter pins (split pins)
6. Nylon nuts

1A TUNE-UP PROCEDURE
Coolant Level (Cold engine)
1. Check that the coolant level is near the radiator inlet
port.
2. Check that the level in the coolant reservoir is be-
tween the FULL and LOW marks.
Add coolant if necessary.
Warning
a) Never remove the radiator cap while the en-
gine is hot.
b) Wrap a thick cloth around the cap and care-
fully remove it.

Drive Belt
1. Check the drive belt for wear, cracks, or fraying.
Replace if necessary.
2. Check the drive belt tension by using the tension
gauge.
Standard belt tension N (kg, lb)

Adjusting bolt
3. Check the drive belt deflection by applying moder-
ate pressure (98 N, 10 kg, 22 lb) midway between
the pulleys.
(1) Alternator belt deflection
New : 6—8 mm (0.24—0.31 in)
Used: 7—9 mm (0.27—0.35 in)
If necessary, loosen the alternator mounting
bolts and adjust the belt deflection by turning
the adjusting bolt.
Tightening torque
31—46 Nm (3.2—4.7 m-kg, 23—34 ft-lb)
(§): 37—52 Nm (3.8—5.3 m-kg, 27—38 ft-lb)
(2) P/S belt deflection
New : 8—10 mm (0.31—0.39 in)
Used: 9—11 mm (0.35—0.43 in)
If necessary, loosen the idler pulley lock bolt
and adjust the belt deflection by turning the ad-
justing bolt.
Tightening torque of lock bolt:
37—52 Nm (3.8—5.3 m-kg, 27—38 ft-lb)

(3) A/C belt deflection
New : 7—9 mm (0.27—0.35 in)
Used: 8—10 mm (0.31—0.39 in)
If necessary, loosen the A/C mounting bolts
and adjust the belt deflection by turning the ad-
justing bolt.
Tightening torque
37—52 Nm (3.8—5.3 m-kg, 27—38 ft-lb)

(4) P/S and A/C belt deflection
New : 7—9 mm (0.27—0.35 in)
Used: 8—10 mm (0.31—0.39 in)
If necessary, adjust the belt deflection using the
same procedure as used for the A/C belt
deflection.
Spark Plug
Check the following points. Clean or replace if
necessary.
1. Damaged insulation
2. Worn electrodes
3. Carbon deposits
4. Damaged gasket
5. Burnt spark insulator
6. Plug gap
