e60 520 2004 m54 水箱
 

e60 的主水箱都通用嗎? ← 主要問提 有想換全鋁的 往拍5000而已

已下屁話
最近又亮燈 大約9個月的時間水少了600cc
不知道是否合理? 因為去年7月才換水路全餐
上水管 下水管 水龜 水普 連接熱水閥三通那一段 都換了

原廠水箱晶 濃度50已上
開暖氣無水箱晶味道 引擎室也無水箱晶之味道
肉眼觀察也無滲漏

木前推判已下幾點可能
1.水箱細微滲漏
2.快速接頭細微滲漏
3.當時師工師傅故意少加
4.熱水閥之後端至熱排有地方細微熱漏
5.屬自然現象 補水即可
6.引擎墊片 應該不會吧...... 沒有奶茶 也沒有氣泡阿 = =

今日發生意外後 留校觀察中 4/1號 e60跟我的愚人節快樂...

小弟也是有類似狀況~後來添加福士水箱止漏劑~開了1年了~水位都正常~短時間沒要修可以試試~小弟是想開久一點之後把冷卻水周邊一起處裡.

我不喜歡添加劑 要就要治本不要治標

當然是有分的.

水箱精濃度太高也不好，以下參考TIS的 說明
Prescribed mixture for coolant:

50 % antifreeze for antifreeze protection up to -38 °C

The original coolant mixture for the initial filling at the factory has this antifreeze-to-water ratio.
If the proportion of antifreeze is less than 40 % to -29 °C (i.e. the water content is higher than 60 %), not only the degree of protection against freezing, but also corrosion protection is reduced. When the water content is too high, this can lead to premature excess temperature in very hot weather or hot climates and as a consequence lead to coolant being ejected out of the system and damage to the engine through excess temperature.
This means that it is essential that an antifreeze and corrosion inhibitor is added even in the tropics.
Too high a concentration, more than 55 % down to -47°C, leads to deterioration of the cooling properties (heat transfer) and protection against freezing-up is modified in the opposite direction, i.e. it also deteriorates.

The amounts of screenwash required for protection against freezing are stated (percentage values) on the containers.
