苏联在寒冷地区使用的汽车,冬季多采用乙二醇基的低凝点冷却液。目前苏联生产有两种乙二醇基的冷却液。气温不低于-35℃的地区用40号;低于这个温度的地方使用65号(见表)。
In the Soviet Union, cars used in cold areas use glycol-based low-freezing point coolants in winter. Currently, the Soviet Union produces two ethylene glycol-based coolants. Use a temperature of not less than -35 ℃ in the area with No. 40; below this temperature use No. 65 (see table).
