REGULAR CHECKS AND MAINTENANCE WORK76
C Checking and adjustment of the fan belt tension
1. Press the fan belt down in the middle, with a force of
approx. 7 kgf (15.4 lbs). The belt tension is correct if it
deflects about 12 to 15 mm (0.47 to 0.59 in.). If
otherwise, loosen bolt and shift the AC compressor in
the direction shown by the arrow.
2. Replace the fan belt if worn out, cracked or torn.
A If the engine is run with a loose fan belt, the belt could
slip and cause insufficient room temperature control.
Check fan belt tension regularly.
3. After adjusting the V-belt, attach the V-belt cover with
the three bolts.
Tightening torque must be between 3 to 5 N-m (2.2 to
3.7 ft-lbs).

A Wait long enough for the radiator coolant to
cool down.

check should be carried out every 200 hours or every 6
months, whichever comes first.

leaks, tighten the hose clamps properly.
2. Should the radiator hoses become swollen, aged or
cracked, they must be replaced and the hose clamps
tightened again properly.
