“宝马软管,塑料冷却系统部件和水泵的寿命,我认为6-7年或90-105k, 冷却水可能会持续(在某些情况下更长)更长时间。”
Buddy of mine has an m5... clock work my friend.. every 40k.
Also, what I have found is that ever 80K or so... full overall of the coolant system needs to be done. I have had many BMW mechanics at reputable independent shops all say the same thing.
This is the nature of this beast... you either live with it or get a Honda”
