防冻液多长时间就应该换一次?

防冻液严格意义上来说并不是一个损耗品,因此没必要在短时间内更换。防冻液变质主要有两大原因,一是使用时间长了之后内部的挥发性物质损耗,造成冰点和沸点降低;二是防冻液中的有机液体时间长了之后溶解大量水道和管路中的有机质,造成浑浊甚至引起变质。
Antifreeze is not strictly a waste product, so it is not necessary to replace it in a short time. There are two main reasons for the deterioration of antifreeze: one is the loss of internal volatile substances after a long time of use, resulting in the reduction of freezing point and boiling point; Second, the organic liquid in the antifreeze solution dissolves a large amount of organic matter in water channels and pipelines after a long time, causing turbidity and even deterioration.
判定防冻液是否变质并不是简单靠肉眼观察是否变色,或者依靠时间来推算,正确的方法是需要专业仪器测量,一般正规的4S店或汽修厂都会有这种设备。当检测下来数值低于标准时,就需要更换防冻液了。目前防冻液的更换主要有重力换液法和循环机换液法两种,简单来说重力换液法就是将水箱底部的螺丝拧开,放掉老冷却液,再拧上螺丝加入新冷却液;循环机换液法就是将水箱盖拧开,把老防冻液直接抽走,再加入新防冻液。严格意义上来说两种方法并没有很大的区别,只是现在4S店将循环机换液法包装成高大上的“黑科技”,目的自然是收取更高的替换费用,因此车主们记得甄别!
To judge whether the antifreeze has deteriorated is not simply to observe whether it has changed color with the naked eye, or to calculate by time. The correct method is to need professional instruments for measurement. Generally, regular 4S stores or repair garages will have this kind of equipment. When the detected value is lower than the standard, it is necessary to replace the antifreeze. At present, the replacement of antifreeze mainly includes gravity replacement method and circulator replacement method. In short, gravity replacement method is to unscrew the screws at the bottom of the water tank, drain the old coolant, and then screw in the screws to add new coolant; The liquid replacement method of the circulating machine is to unscrew the water tank cover, directly pump away the old antifreeze, and then add new antifreeze. Strictly speaking, there is no great difference between the two methods, but now the 4S store packages the liquid change method of the circulator as a "black technology" on a tall scale. The purpose is naturally to charge a higher replacement fee, so car owners remember to distinguish!
还需要指出的是,很多老司机认为防冻液并不需要更换,只是缺少时及时添加就行,这种想法是完全错误的。因为目前的车辆只要冷却系统没有故障就不会出现防冻液减少的问题,而反过来防冻液减少就一定意味着冷却系统出现渗漏,需要及时检查水管、接头处是否老化开裂。
It should also be pointed out that many old drivers think that antifreeze does not need to be replaced, but can be added in time when it is lacking. This idea is completely wrong. As long as the cooling system of the current vehicle is not faulty, there will be no problem of antifreeze reduction. Conversely, the reduction of antifreeze must mean that the cooling system leaks. It is necessary to check whether the water pipes and joints are aging and cracking in time.
