Show original supplier description
The BMW Genuine Parts 11531438632 is a direct replacement water hose assembly, specifically designed for various BMW 5 Series models. This hose circulates hot engine coolant from the cooling system to the vehicle's heater core, playing a critical role in the cabin's climate control system. Signs of a failing heater hose include visible cracks, leaks at connections, softening or deterioration of the rubber, low coolant levels, a coolant smell, or a lack of heat from the heater. This part fits the following BMW models: 1997-2000 528i (Sedan and Wagon), 2001-2003 525i (Sedan and Wagon), and 2001-2003 530i (Sedan). It is important to note that some users have reported issues with the end alignment pins being 180 degrees off, requiring minor modifications or the use of specific hose clamps to install correctly. This genuine BMW part is guaranteed by BMW's factory warranty.
