1. If the engine coolant temperature is within a range of
10 ~ 55°C, drain the coolant and fill half a plastic cup
with it.
CAUTION
When taking out a sample of coolant from the
supplementary tank, it is difficult to measure the
precise concentration. Always take out sample by
opening the drain plug of coolant.
2. Soak the test sheet in the coolant and take it out after
3 ~ 5 seconds. Shake the sheet to remove the
remaining coolant.
3. Wait for approximately 45 seconds until the test sheet
changes its colour.
CAUTION
Measurement time should not exceed 75 seconds.
The color changes as time passes.
4. Check the color on test sheet.
1) Compare the color of part (A) on the test sheet to
the color of GLYCOL/FREEZEPOINT (End pad) of
the standard color table.
2) Compare the color of the test sheet (B) to the color
of MOLYBDATE (Middle pad) of the standard color
table.
3) Compare the color of the test sheet (C) to the color
of NITRITE of the standard color table.
5. Compare and confirm the parts with identical colors
on the test sheet and the standard color table.
1) Compare the changed pink color part A of the test
sheet with the GLYOOL/FREEZEPOINT (End pad) of
the standard color table on top of the container and
confirm the concentration. The concentration
indication has to be within the color scope of 33~50%
2) It should be maintained at the optimum range, in
the green section between 0.3 to 0.8 where the color
of MOLYBDATE (Middle pad) on the standard color
table (which is identical with the Middle (B) of the test
sheet) is crossed with the color of NITRITE on the
standard color table (which is identical with the (C) of
the test sheet).
3) If it is above 0.8, drain a little coolant and then add
clean tap water to adjust the concentration.
CAUTION
If the color on the test sheet does not match the color
of the standard color table, find a middle color on the
standard color table. For example, if the color of (C)
of the test sheet matches D and F on the NITRITE of
the standard color table, select E.
To prevent corrosion inside of the engine cooling
unit, drain the coolant and replace it with new
coolant once a year.
