    Even in the areas where freezing is not an issue, the use of anti- freeze coolant is essential. KOMATSU machines are supplied with KOMATSU Supercoolant (AF-NAC). KOMATSU Supercoolant (AF-NAC) has excellent anticorrosion, antifreeze and cooling properties and can be used continuously for 2 years or 4000 hours.
  • Page 286 To maintain the anticorrosion properties of Supercoolant (AF- NAC), always keep the density of Supercoolant between 30% and 68%. When using KOMATSU Supercoolant (AF-NAC), there is no need to use a corrosion resistor. When no corrosion resistor is used, use the special cover (600- 411-9000).
  • Page 287 Always use KOMATSU genuine super coolant (AF-NAC) for the coolant. Use tap water to dilute the coolant. If river water, well water or other such water supply must be used, contact your KOMATSU distributor. We recommend use of an antifreeze density gauge to control the mixing proportions.
