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

I just need replace it on schedule.
酷冷掉了？要麽係統管路滲漏；要麽參於燃燒…
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 最頭疼。 家用空調，最後還是換新的。R22現在太貴了，備用的賣了可以換半個空調啊。 -PrimeryColor- ♀ (0 bytes) () 08/10/2023 postreply 17:25:40

• 謝謝指正！上一次有壇友車的循環水箱不通，是否與酷冷變質腐蝕有關？反正我3~4年換水，係統內部十分幹淨。 -老金工- ♂ (0 bytes) () 08/10/2023 postreply 17:50:14

• 見笑了。 沒有看仔細。是冷卻液，不是冷媒。大家當笑話得。LOL。禁網半天。 -PrimeryColor- ♀ (0 bytes) () 08/10/2023 postreply 17:54:55
