Super Coolant (AF-ACL) has an anti-corrosion effect as well as an antifreeze effect. The ratio of antifreeze to water depends on the ambient tempera- ture, but to obtain the corrosion resistance effect, a minimum ratio of 30% by volume is necessary. To determine the proportion for mixing coolant with water, check the lowest temperature in the past and decide the proportion of the mix from the table below. Set to a temperature 10°C (50°F) lower than the minimum tempera- ture. Table of ratios of water and anti-freeze. Antifreeze (e) A WARNING Antifreeze is flammable, so keep it away from flames. Never smoke when handling antifreeze. Use tap water as the coolant.
If the only available water is river water or well water, please contact your Komatsu distributor for advice. We recommend using an antifreeze density gauge to control the proportion of the mix.
