Upper Radiator Hose, Rein - E30 318is (M42), Rein - 11531717622

This Upper Radiator Hose is a stock replacement for your E30 318is, 1989, 1990, 1991, which came with the 16 valve M42 engine. 

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.
