That did happen on the 300SE. Today #1 boy drags me out to the car to show me the coolant mess near the overflow tank. Having not seen it before, I thought it was his head gasket. The spew was not at all as dramatic as he portrayed. Seemed to come from the overflow hose from the rad. Closer look shows a micro crack. Hot fluid was escaping, but not horrid. No shoe goo, so I drug out the spare tank and had him clean it out and install.
