Gates molded coolant hoses are precision-manufactured to fit upper, lower, bypass, heater, and other coolant applications with factory specifications. The advanced EPDM compound resists the electrochemical degradation that occurs when hoses, coolant, and metal fittings create a galvanic reaction, significantly extending service life. Gates recommends replacing hose clamps each time a new coolant hose is installed for optimal performance. Not for use in fuel or oil transfer applications.
