Anti-Freeze
• There are two types of anti-freeze available: use the permanent
type (PT) for this engine.
• Before adding anti-freeze for the first time, clean the radiator
interior by pouring fresh, soft water and draining it a few times.
• The procedure for mixing water and anti-freeze differs
according to the maker of the anti-freeze and the ambient
temperature. Basically, it should be referred to SAE J1034
standard, more specifically also to SAE J814c.
• Mix the anti-freeze with fresh, soft water, and then fill into the
radiator.
• When the anti-freeze is mixed with fresh, soft water, the
anti-freeze mixing ratio must be less than 50 %.
* At 1.013 × 100000 Pa (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.
• The above data represents industrial standards that
necessitate a minimum glycol content in the concentrated
anti-freeze.
• When the coolant level drops due to evaporation, add
fresh, soft water only to keep the anti-freeze mixing ratio
less than 50 %. In case of leakage, add anti-freeze and
fresh, soft 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.)
