Show original supplier description
The BMW Genuine Parts 11531738055 is a radiator return hose, specifically designed to facilitate the flow of coolant from the heater core back to the engine. As a Genuine BMW part, it guarantees the same quality and fitment as the original component installed at the factory, adhering to BMW's stringent manufacturing standards. Heater hoses, like all coolant hoses, are subjected to extreme temperature fluctuations which can lead to deterioration over time. Signs of wear such as bulges, cracks, or softness indicate that a replacement is necessary to prevent leaks and maintain the integrity of your BMW's coolant system. This hose plays a vital role not only in the cabin's heating functionality but also in overall engine reliability by preventing overheating. Symptoms of a failing heater hose include visible cracks, leaks at connection points, hose material becoming soft or deteriorated, a consistently low coolant level, a coolant smell within the cabin or engine bay, or a lack of heat from the vehicle's heater. The Genuine BMW 11531738055 is engineered to withstand these conditions, ensuring consistent performance. This part is specifically designed for select BMW 328i (2.8L L6, Chassis E36) models from 1996-1999, and BMW 323i (2.5L L6, Chassis E36) models from 1998-1999. Fitment includes both convertible and sedan body styles with automatic or manual transmissions.
