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 cu
p
wi
th 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
col
or of GLYCOL/FREEZEPOINT (End pad) of t
he
st
andard 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 indicati
on
has
to be within the color scope of 33~50%.
2) The state of additives for anticorrosion is shown
on
t
he point where the color of MOLYBDATE (Middl
e
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 tabl
e
(
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.
