Coolant issue.

[Andyk]

Hello all, this is my first thread so hope you can help.
My wife picked up her 2001 x5 4.4 yesterday from a local dealer. This was her dream car so you can imagine how disappointed she was when after a 50 mile trip the coolent warning light came on only to find that the coolent was spewing from the top of the cap. I took the cap off and it looks like it could be damaged so we have taken the car back for them to sort. My only concern is that it could be more serious...like headgasket....The water only comes out once the car is stopped and the engine in turned off....OK so we have the warrenty which hopefully will cover....just wondered about your thought on this.
