Gates precision-manufactures these hoses with exclusively-developed factory processes to ensure compatibility and exceptional performance to specific vehicle manufacturer specifications.

Quality & Durability: Gates engineered this hose with superior electrochemical resistance to prevent micro-cracks that form when the hose, liquid coolant, and engine/radiator fittings create a galvanic cell reaction. This advanced EPDM material compound ensures your coolant hoses last longer and keep your engine systems running stronger.

Installation Note: Gates recommends replacing hose clamps each time a new coolant hose is installed for optimal sealing and performance. Not intended for fuel or oil transfer applications.
