Use of Anti-Freeze
Freezing of the coolant may result in damage to the
engine. Mix in anti-freeze (Long Life Coolant) when
the outside temperature will drop below 0°C (32°F)
during the winter.
The mixture ratio of anti-freeze differs depending upon
the anti-freeze manufacturer and temperature. Follow
the instruction for the anti-freeze.
Cleaning of Radiator
WARNING: Make sure to stop the engine
when cleaning the radiator. Placing your
hands in this area while the engine is op-
erating may result in serious injury.
FIG. 6-17: Cleaning Insect Net ,1
When the tractor is operated in fields or at night, the
insect net may become clogged with grass, straw,
insects and other matter.
Open the hood, pull out the insect net and clean it.
Cleaning Radiator Core ,2
Wash away any dirt or other foreign matter in between
the fins with tap water.
IMPORTANT: When the radiator becomes clogged,
it will overheat, resulting in increased
oil consumption.
Be careful not to apply high pressure
water directly to the radiator as this
may result in deformation of the fins.
Do not directly spray water on the
electrical wiring or electrical parts
around the engine.
FIG. 6-18:
Correct fan belt tension helps to insure
adequate coolant flow through cylinder block and ra-
diator. Belt is correctly tensioned when belt deflection
is approximately 14 mm when thumb pressure (10kgf)
is exerted at center of belt span.
CAUTION: Due to muffler position, allow
it to cool before checking or adjusting fan
belt tension.
FIG. 6-19:
To adjust belt tension, loosen alternator
pivot bolt, 1, and tensioning bracket bolt, 2. Pull out-
ward on top of alternator to correctly tension belt and
tighten bolt, 2, first and then tighten pivot bolt, 1.
IMPORTANT: Do not pry against alternator hous-
ing or pulley. Carefully pry against
alternator mounting flange to prevent
damage.
