Changed the cooling system (Rad, WP, thermo...etc.) and left the plastic shield off to check for leaks....but like an idiot left the plastic piece that was hanging below the radiator....then promptly drove over it as it fell off about 3 miles down the road. Dealer can't seem to find it on the system or at realoem. Any of you fellow 1998 MZ3 buds know what this dang part is? It wasn't very big (maybe 18 inches long?), and seemed to hook onto a lip either on or right below the radiator. Air duct? Splitter? Tried searching here and couldn't find a definite answer....
