This hose joins the water pump to the thermostat. Like most serviceable items in your BMW's cooling system, these cooling hoses are one of the first areas to degrade and become brittle, crack, split or swell — this can leave you stranded and your car at risk of overheating. Preventative maintenance is a must. We offer this OE-Quality replacement from Febi Bilstein.
