CHECKING- THE RADIATOR COOLANT LEVEL

in the coolant.
For replenishment, remove the radiator cap and enter water

PRECAUTIONS ON COOLING SYSTEM IN COLD
WEATHER
Frozen cooling water may damage the cylinder block. To avoid
such a trouble, mix antifreeze into cooling water, or thoroughly
drain cooling water from the cylinder block in case the tractor is
stored or left unused for a long time in cold weather.
ANTIFREEZE
When adding antifreeze solution, the following rules should be
observed, otherwise, the cylinder block will rust.
1. This tractor's engine is of a diesel type and its cylinder block
is made of cast iron. Therefore, suitable anti-freeze solution
for such a cast engine block must be used.
2. Before adding mixture of antifreeze and water, completely
drain cooling water and clean the radiator with detergent.
3. Water to be added to antifreeze should be clean soft water.
4. When antifreeze is no longer used, drain and wash the cool-
ing system using detergent and fill it again with clean water.
Do not re-use antifreeze drained from the engine.
