A good quality system such as my Lexus, coolant never lost

I just need replace it on schedule.
酷冷掉了？要么系统管路渗漏；要么参于燃烧…
Google: Antifreeze doesn't evaporate but the water does. The reason is that the antifreeze contains several chemical components (80-95% ethylene glycol) that do not evaporate. However, if antifreeze is exposed to the air, it will evaporate over a period of time.

所有跟帖： 

• +1. micro leaking 最头疼。 家用空调，最后还是换新的。R22现在太贵了，备用的卖了可以换半个空调啊。 -PrimeryColor- ♀ (0 bytes) () 08/10/2023 postreply 17:25:40

• 谢谢指正！上一次有坛友车的循环水箱不通，是否与酷冷变质腐蚀有关？反正我3~4年换水，系统内部十分干净。 -老金工- ♂ (0 bytes) () 08/10/2023 postreply 17:50:14
