Description Reviews MINI Cooper S Coolant Hose #9! Why do we call it hose #9? Because it's #9 in the diagram break down for the parts catalog. This hose goes from the water pump to the lower radiator connection. We have installed a few of these hoses over the years and have seen wear on this hose from wearing on the fan housing. We only see this wear on higher mile cars, and then only in a hand full of cars. If you're replacing the radiator or a supercharger, this might be an item that you want to think about replacing. We have been surprised how well the rubber has held up over the years on the MINI, but we all know MINI owners take really good care of their cars. So if you have bought it used you might want to look it over. Thisis a MINI OEM Part. Fits all generation 1 MINI Cooper S's, 2002-2006 R53 MCS & 2005-2008 R52 MCS convertibles. Comes with new clamps on each side. Don't forget some quality fluid and make sure it's mixed to 50/50.
