Flashing 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 then fill in to the radiator.
* At 760 mmHg pressure (atmospheric). A higher boiling point is
obtained by using a radiator pressure cap which permits the
development of pressure within the cooling system.
NOTE
■
• The above date 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.)
