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. Having the proper hose is crucial to cooling system performance. A non-stock or generic hose may not have the same length or shape and could diminish cooling or fail to fix annoying leaks.
