Show original supplier description
The BMW Genuine Parts 11531438633 is a stock replacement auxiliary water pump-to-expansion tank hose, engineered to maintain the original cooling system performance in your BMW. This rubber hose allows for essential movement and flexibility, crucial for reliable operation and preventing premature failure. This hose is specifically designed for the E39 chassis, fitting the 525i (M54 2.5L), 528i (M52 2.8L), and 530i (M54 3.0L) models from 1999 to 2003. It directly replaces BMW part number 11531438633. It is important to replace coolant hoses as a preventative maintenance measure before they degrade and fail. A failed hose can lead to significant coolant loss, potentially causing overheating and loss of vehicle control. This replacement hose ensures proper fitment and integration with your BMW's cooling system, avoiding the issues that can arise from using non-stock or generic alternatives. Special Application Notes indicate that this hose is for the 528i model only during the 1999-2000 model years.
