SERVICE PROCEDURE
When deciding the ratio of antifreeze to water, check the lowest temperature in the past, and decide from the mixing
table given below.
It is actually better to estimate and temperature about 10°C (18°F) lower when deciding the mixing ratio.
The mixing ratio depends on the ambient temperature, but it should always be a minimum of 30% by volume
(antifreeze/total amount of coolant x 100).
Even in areas where it is not necessary to prevent freezing, use Supercoolant (AF-NAC) at a mixing ratio of at least
30% to prevent corrosion of the cooling system.
The freezing temperature of undiluted antifreeze is -15°C (5°F). Do not store undiluted antifreeze at a temperature
of below -15°C (5°F).

WARNING
Antifreeze coolant is flammable, so keep it away from flame.
Antifreeze coolant is toxic. When removing the drain plug, be careful not to get water containing antifreeze coolant on you. If it
gets in your eyes, flush your eyes with large amount of fresh water and see a doctor at once.
Use antifreeze and appropriate water for diluting (for details, see "COOLANT AND WATER FOR DILUTION (PAGE
4-6)")
We recommend use of an antifreeze density gauge to control the mixing proportions.
WARNING
When removing the drain plug, be careful not to be covered with the drained coolant.
