Upper Radiator Hose, Rein - E82 135i, E9X 335i, E84 X1 35i, E89 Z4 35i (N54, N55)

Top radiator hose for N54 and N55 engines used on E82 135i, E9X 335i, E84 X1, E89 Z4. This hose returns hot coolant from the cylinder head to the radiator. Rubber hoses are ideal when new, as they allow some movement and flexibility during driving. The only problem is that they begin to degrade as they age, and can eventually fail, leaving you with the potential for loss of control from coolant spilling and/or an overheating situation. Replace your radiator hoses as a preventative measure before they fail in order to save you from further headaches and expenses.
