ANTI-FREEZE
* At 760 mmHg pressure (atmosph-
eric). A higher boiling point is ob-
tained by using a radiator pres-
sure cap.
This tractor is lled with 50% of eth-
ylene glycol at factory.
If the anti-freeze has been replaced
by tap water later on, the coolant can
freeze, leading to damage to the cyl-
inder and radiator when the ambient
temperature is below zero
(32 °F).
Therefore, make sure to change wa-
ter into anti-freeze before winter sea-
son comes.
When changing the anti-freeze with
one of another type, ush the cooling
system several times and contact a
professional for the mixture ratio.
The temperatures shown on the
left are 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 specied 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 cooling water.
(Anti-freeze contains an anti-cor-
rosive agent, which will react with
the radiator cleaning agent form-
ing sludge which will affect the
engine parts.)
