For all owners of duratec engines with a bad overflow this is what I do with mine. After a deep investigation the Mondeo mk3 has almost the same accesories, but because is a late model there is a lot of improvements in the design of many items, just like the overflow tank. Here in mexico you can find this tank for about 120 or 130 USD but there are huge noticiable differences that worth the trouble for the people living in the states to get one of this. Here are some pics to get clear what Im talking about. The part number that is completely interchangeable with our Mystique or contour and even the cougar is: 1S71-8K218-AB
