color of
the strip with color blocks of a row at
the upper part of the standard color
chart (below of the letter
″
GLYCOL/
FREEZE POINT ″ ). Same color in the
block of the row means the content
of anti-freeze in the coolant. (Normal
range is between 33% and 50%.)
(2) Compare the middle pad ″ b) ″ color of
the strip with the color that the col-
umn block color of MOLYDATE at
the left side of the table intersects
the row block color of NITRITE at the
bottom (pad
″ c) ″ color of the strip) on
the table ″ SCA Units per Litre ″ .
(Normal range of ″ SCA Units per
Litre ″ is between 0.3 and 0.8 :
″ green color area ″ )
During the comparison, if uncertain about color match, pick the lower numbered block.
(example: if the color of NITRITE pad is between standard color
″ D ″ and ″ F ″ , then use
column E.)
(3) If the value of ″ SCA Units per Litre ″ is less than 0.3, refill the DCA4 liquid (anti-corrosion agent) a
little, But larger than 0.8, Drain some amount of engine coolant and replenish the fresh water
instead. The content of the anti-freeze and anti-corrosion agent can be regulated by this way.
Every year coolant must be replaced. It is essential the coolant should be mixture
of fresh water, proper anti-freeze and anti-corrosion agent.
4.3.3. Anti-freeze
The anti-freeze, 35 ~ 40% of the whole coolant, is always to be used to prevent the cooling system from the
corrosion. And in winter the amount of anti-freeze shown in the following table should be used in accordance
with the ambient temperature.
As the individual freezing points corresponding to the proportions of antifreeze in the table are subject to
change slightly according to the kind of antifreeze, you must follow the specifications provided by the anti-
freeze manufacturer.
