My wife claims that all she did was run over a curb today, and that all of the coolant leaked out of the car (03 S-type 4.2). She recovered several large pieces of the undercarraige protector with one looking as though it contained a box. I will be getting under the car tomorrow evening to look at the damage. I have never needed to work on this car before (unlike my porsche); is their anything that I should keep and eye out for? Is their a good linkfor a coolant system parts diagram?

Thanks in advanced
