Anti-Freeze
If cooling water freezes, the cylinders and radiator can be
damaged. It is necessary, if the ambient temperature falls below
0
°
C (32
°
F), to remove cooling water mix it with anti-freeze and
full the radiator with 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 maker of the anti-freeze and the ambient
temperature, basically should be referred to SAE J1034, more
specially also to SAE J814c.
4. Mix the anti-freeze with water, and then fill in to the rediator.
* At 101 kPa (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 concentrates
anti-freeze.
• When the cooling water 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 cooling water. (Anti-freeze contains an
anti-corrosive agent, which will react with the radiator
cleaning agent forming sludge which will affect the engine
parts.)
