24. SERVICE PROCEDURE When deciding the ratio of antifreeze to water, check the lowest tem- perature in the past, and decide from the mixing rate table given be- low. It is actually better to estimate a temperature about 10°C lower when deciding the mixing rate. Mixing rate of water and antifreeze 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.
