冬季彻底放净冷却水,是发动机防冻的一个重要措施。冬季当气温下降至0℃以下时,拖拉机、汽车等机动车辆停止使用时必须放净冷却水,否则因冷却水冻结,会冻裂水箱、气缸盖和气缸体等部件,造成严重的事故。我们发现许多驾驶员在给机车放水时,掌握不好放水的方法。有的驾驶员还错误地认为,停车后只要把放水开关打开就行了。其实不然,近年来从我县发生的几起“冻车”事故来看,出现冻车的原因一般有三种:一是没有掌握好放水温度;二是忘记了放水;三是没有彻底把水放净。正确的放水方法是:
Completely let the net cooling water in winter is an important measure of the engine antifreeze. When the temperature drops below 0 ° C in winter, the cooling water must be drained when the motor vehicles such as tractors and automobiles stop using.

Some drivers also mistakenly believe that as long as the water after the parking switch is turned on. In actual fact, in recent years, from my county a few “frozen car” accident, there are three reasons for the emergence of frozen vehicles: First, do not have a good water temperature; second, forget the water; Third, there is no water net. The correct way to drain is:
