(1) Compare the end pad “a)” 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 column 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.
