Inspection Procedures of Coolant Concentration
Check the concentration of DCA4 in coolant using the
inspection kit shown below.
Name of Kit
Inspection Kit CC2602
 Outline
1. Both A and B reagents are coated on CC2602 test paper,
allowing to measure the color changes on both A and B
reagents.
2. At the same time, one more reagent is coated to easily
determine the antifreeze concentration through color
change.
(The antifreeze concentration checked by this method
should be just a guide line. When the exact antifreeze
concentration is required, measure it using a specified
equipment.)
3. Do not use diluted coolant for measurement. Collect
coolant into a sample container. Directly dip the
test paper into the collected coolant. Compare the
reagent color change on the test paper with the color
specimen coated on the test paper box 45 seconds after
desiccating.
