Thanks Gary.

I understood everything you said about the pressure cap, but, I just can't make sense out of the hose flow explanation.

However, this thread is clearly all about the pressure cap; so, I just opened a separate thread solely on the topic of how the overflow (aka bypass) hose works, over here:
> E39 (1997 - 2003) > Can someone explain the flow through the expansion tank so-called "overfow" hose?

Please read the suggested threads and add value, either by pictures or by descriptions, so the next person stands on your shoulders.
