Cautions for Using Coolant:
Use coolant of specified mixing rate. (The mixing rate of 425cc KYMCO SIGMA coolant
concentrate + 975cc distilled water is 30%.)
Do not mix coolant concentrate of different brands.
Do not drink the coolant which is poisonous.
The freezing point of coolant mixture shall be 5• •lower than the freezing point of the riding
area.
