Ok, I finally have to simply ask the question. Where the heck is my overflow bottle located on my 1999 XK8? Not the expansion reservoir, but the overflow bottle. There has to be one somewhere, right? I've searched the forum, searched the web, and all I've been able to discern is that on 1997 & 98 they are hidden in the fender, but there's no mention ANYWHERE of where the dingdang 1999 overflow bottle is located.

Hepmeh Hepmeh!!!

 

Front wheel arch behind the liner I think .

 

Yes, front passenger side.

 

Front passenger side wheelwell, behind the liner towards the rear.

 

does a 2003 xk8 have one?
