Flushing Cooling System and Changing Coolant (Continued)
■ Anti-Freeze
If coolant freezes, it can damage the cylinders and radiator. It is
necessary, if the ambient temperature falls below 0 °C (32 °F), to
remove coolant after operating or to add anti-freeze to it.
1. There are two types of anti-freeze available ; use the permanent
type (PT) for this engine.
2. Before adding anti-freeze for the first time, clean the radiator
interior by pouring fresh water and draining it a few times.
3. The procedure for mixing of water and anti-freeze differs
according to the make of the anti-freeze and the ambient
temperature, basically is should be referred to SAE J1034
standard, more specifically also to SAE J814c.
4. Mix the anti-freeze with water, and ten fill in to the radiator.
*At 760 mmHg pressure (atmospheric). A higher boiling points is
obtained by using a radiator pressure cap which permits the
development of pressure within the cooling system.
NOTE■
• The above data represent industry standards that
necessitate a minimum glycol content in the concentrated
anti-freeze.
• When the coolant level drops due to evaporation, add water
only. In case of leakage, add anti-freeze and water in the
specified mixing ratio.
• Anti-freeze absorbs moisture. Keep unused anti-freeze in a
tightly sealed container.
• Do not use radiator cleaning agents when anti-freeze has
been added to the coolant. (Anti-freeze contains an anti-
corrosive agent, which will react with the radiator cleaning
agent forming sludge which will affect the engine parts.)

Bleeding Fuel System
Air must removed :
1. When the fuel filter or lines are removed.
2. When tank is completely empty.
3. After the tractor has not been used for a long period of time.
Bleeding procedure is as follows.
1. Fill the fuel tank with fuel, and open the fuel cock (1).
2. Open the air vent cock (2) on the fuel injection pump.
3. Start the engine and run for about 30 seconds, and then stop the
engine.
4. Close the air vent cock.
IMPORTANT■
• Always close the air vent cock except for bleeding fuel lines.
Otherwise, engine runs irregularly or stalls frequently.
