24. SERVICE PROCEDURE When deciding the ratio of antifreeze to water, check the lowest temperature in the past, and decide from the mixing rate table given below. It is actually better to estimate a temperature about 10˚C lower when deciding the mixing rate. Mixing rate of water and antifreeze Min. atmospheric temperature Amount of 85.5 antifreeze 22.57 18.81 Amount of 85.5 water 22.57 18.81 WARNING Antifreeze is flammable, so keep it away from any flame. Use city water for the cooling water. 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.
