Heinmo Aluminum Auto R53 Radiator Coolant Expansion Alloy Tank for Cooper S R52 Convertible R53 3-Door Hatchback 2002-2008

Fits fine, the locating bolts could be longer, and the cap leaks.. But it will do as I save for a better replacment.

Arrived in 15 days, have not installed it yet but seems to fit perfectly. Perfect quality for the money
