The cooling medium, or coolant, in them is either water or some low-freezing liquid, called antifreeze. 系统所用冷却介质或是冷却液常委水或其他低凝固点液体，称为抗凝剂。
A water-cooling system means that water is used as a cooling agent to circulate through the engine to absorb the heat and carry it to the radiator for disposal. 水冷系统意味着水将用作冷却介质，用于在发动机中循环吸收热并将之带到散热器中散出。
Do not use coolant additives that are claimed to improve engine cooling. 不要使用声称能提高引擎冷却效果的冷却剂添加剂。
Frequently the cause is poor mold cooling and this is frequently caused by a lack of coolant rather than its temperature. 影响脱模的原因常常是差的模具冷却效果，而这又是由于缺乏冷却剂，而不是温度的设定所致。
