Measurement of Coolant Concentration
•
Special Tools
The coolant concentration can be measured as follows.
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.
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 about 45 seconds until the test sheet
changes its color.
4. Check the color on test sheet.
EDL0213002A
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.
EDL022154A
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) The state of additives for anticorrosion is shown on
the point 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). It
should be maintained at the optimum range, in the
green section between 0.3 to 0.8.

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.
CAUTION
Measurement time should not exceed 75 seconds.
The color changes as time passes.
