Chinese-English Translation:
冷却液和防冻液是一样的，只是同一个物品的两种称呼。防冻液的全称叫防冻冷却液又称冷却液，意思是有防冻功能的冷却液。防冻液可以防止在冬季停车时冷却液结冰而胀裂散热器，冻坏发动机气缸体或盖。
Coolant and antifreeze are the same, just two names for the same thing. The full name of antifreeze is antifreeze coolant, which means the coolant with antifreeze function. Antifreeze can prevent the radiator from cracking and the engine cylinder block or cover from freezing when the coolant is stopped in winter.

相信广大车友对于冷却液和防冻液这两个名词一定不会陌生，但是也有一些不熟悉的朋友会分不清这两样东西有什么区别。
I believe that the majority of car drivers will not be unfamiliar with the two terms coolant and antifreeze, but some unfamiliar friends will not be able to distinguish the two things.
冷却液是什么
What is the coolant
甘油型冷却液沸点高、挥发性小、不易着火、无毒、腐蚀性小，但降低冰点效果不佳、成本高、价格昂贵，用户难以接受，只有少数北欧国家仍在使用；乙二醇型冷却液是用乙二醇作防冻剂，并添加少量抗泡沫、防腐蚀等综合添加剂配制而成。
The glycerol type cooling liquid has high boiling point, small volatility, no easy ignition, no toxicity and little corrosion. However, the freezing point effect is not good, the cost is high, the price is high and the users are hard to accept. Only a few northern European countries are still using it. Glycol type coolant is prepared by using ethylene glycol as antifreeze and adding a small amount of anti foam and anticorrosive additives.
由于乙二醇易溶于水，可以任意配成各种冰点的冷却液，其最低冰点可达-68℃，这种冷却液具有沸点高、泡沫倾向低、粘温性能好、防腐和防垢等特点，是一种较为理想的冷却液，目前国内外发动机所使用的和市场上所出售的冷却液几乎都是这种乙二醇型冷却液。压缩机冷媒有时也被称为冷却液。
It is easy to dissolve in water from glycol, and it can be allocated into any coolant at any freezing point. Its lowest freezing point can reach -68 degrees. This kind of coolant has the characteristics of high boiling point, low foam tendency, good viscosity temperature performance, antisepsis and anti scaling. It is an ideal coolant. Compressor refrigerant is sometimes referred to as coolant.
防冻液是什么
What is antifreeze
防冻液的全称应该叫防冻冷却液，意为有防冻功能的冷却液。防冻液可以防止在寒冷冬季停车时冷却液结冰而胀裂散热器和冻坏发动机气缸体或盖，防冻液是一种含有特殊添加剂的冷却液，主要用于液冷式发动机冷却系统，防冻液具有冬天防冻，夏天防沸，全年防水垢，防腐蚀等优良性能。
The full name of antifreeze should be called antifreeze coolant, which means the coolant with antifreeze function. Antifreeze can prevent the radiator from cracking and the engine cylinder block or cover from freezing when the coolant stops in cold winter. Antifreeze is a kind of coolant with special additives, which is mainly used in the cooling system of liquid-cooled engine. Antifreeze has excellent performance such as antifreeze in winter, anti boil in summer, water-proof and anti-corrosion throughout the year.
