The BMW Genuine Parts lower radiator hose is a direct stock replacement specifically designed for the E46 M3's S54 cooling system. Constructed from rubber, this hose offers essential flexibility and movement during operation, which is crucial for the longevity of cooling system components. Over time, rubber hoses can degrade, leading to potential coolant loss and overheating, making timely replacement a critical preventative measure. This hose replaces the original BMW part #11537830715. Manufactured by Rein (CRP) Automotive, it is an original equipment supplier to BMW, ensuring it meets all original design, fitment, and performance requirements. As an OEM part, it provides a virtually identical alternative to Original BMW parts without the premium price tag and is TUV approved. This part comes with a two-year warranty. Special Application Notes: The coolant temperature sensor is sold separately and is located in the lower hose. Please see related items for the correct sensor.
