Anti-freeze
• There are 2 types of anti-freeze available : use the permanent
type (PT) for this engine.
• When you add anti-freeze for the first time, flush the water
jacket and radiator interior with clean, soft water several times.
• The brand of the anti-freeze and the ambient temperature have
an effect on the procedure to mix water and anti-freeze. Refer
to the SAE J1034 standard, especially to the SAE J814c.
• Mix the anti-freeze with clean, soft water, and then fill into the
radiator.
IMPORTANT
• Make sure that when you mix the anti-freeze and water, the
ratio of anti-freeze is less than 50 %.
* At 1.01 × 100000 Pa (760 mmHg) pressure (atmospheric). Use a radiator pressure
cap that lets the pressure collect in the cooling system to get a higher boiling point.
NOTE
• The above data is the industrial standards that shows the
minimum glycol content necessary in the concentrated
anti-freeze.
• When the coolant level decreases because of evaporation,
add clean, soft water only to keep the anti-freeze mixing
ratio less than 50 %. If there is a leakage, add anti-freeze
and clean, soft water in the specified mixing ratio.
• The anti-freeze absorbs moisture. Keep new anti-freeze in
a tightly sealed container.
• Do not use the radiator cleaning agents after you add
anti-freeze to the coolant. Anti-freeze contains an
anti-corrosive agent, which reacts with the radiator
cleaning agent to make sludge and cause damages to the
engine parts.
