Detailed Product Description

The Gates Molded Coolant Hose 23646 is engineered to meet the specific cooling system requirements of the Mitsubishi Eclipse. Its EPDM construction offers excellent resistance to heat, ozone, and coolant chemicals, which helps maintain hose integrity over time. The molded design allows for a precise fit, reducing the risk of leaks and ensuring proper coolant circulation. With a centerline length of 14.4 inches (366 mm) and matching inside diameters of 1.35 inches (34 mm) on both ends, this radiator coolant hose is optimized for the Eclipse’s cooling system layout. The absence of an internal spring means the hose maintains a smooth internal surface, minimizing flow restrictions.
