This Genuine Gates Upper Radiator Hose is designed to ensure your vehicle's cooling system functions optimally. The cooling system is crucial for maintaining your engine's reliable temperature by circulating coolant through pipes and hoses. Over time, these hoses can become frail. This hose has an inner diameter of 30mm and is black in colour. It is sold individually. The cover is heat and ozone resistant and the hose itself resists electrochemical degradation, a common cause of hose failure. It is suitable for upper, lower, bypass, heater and other automotive coolant hose applications.
