9) Run engine, with radiator cap removed, until radiator upper
hose is hot.
10) With engine idling, add coolant to radiator until level reaches
the bottom of filler neck. Install radiator cap, making sure
that the ear of cap lines up with reservoir hose.
Water Pump Belt Tension
1) Inspect belt for cracks, cuts, deformation, wear and cleanli-
ness. If it is necessary to replace belt, refer to “Water Pump
Belt and Cooling Fan” in this section.
2) Check belt for tension. Belt is in proper tension when it
deflects 4.5 to 5.5 mm (0.18 – 0.22 in.) under thumb pres-
sure (about 10 kg or 22 lb.).
Water pump belt tension
“a” : 4.5 – 5.5 mm (0.18 – 0.22 in.) as deflection / 10 kg (22
lbs)
3) If belt is too tight or too loose, adjust it to proper tension by
displacing generator position.
4) Tighten generator adjusting bolt and pivot bolts as specified
torque.
Tightening torque
Generator adjusting bolt (a) : 23 N·m (2.3 kg-m, 17.0 lb-ft)
Generator pivot bolts (b) : 50 N·m (5.0 kg-m, 36.0 lb-ft)
5) Connect negative cable at battery terminal.WARNING:
Disconnect negative cable at battery before checking and
adjusting belt tension.
NOTE:
When replacing belt with a new one, adjust belt tension
to 3 – 4 mm (0.12 – 0.16 in.).

WATER PUMP BELT TENSION INSPECTION
1) Check belt tension. It should be within specification. Refer to
“Water Pump Belt Tension” in this section.
2) If tension is out of specification, adjust it.
For its adjustment, refer to “Water Pump Belt Tension” in this
section.
After adjustment, be sure to tighten bolts.
COOLING FAN CLUTCH INSPECTION
Inspect fluid coupling for oil leakage.
If necessary, replace fan clutch assembly. Do not disassemble
