Detailed Product Description

This radiator coolant hose is engineered from EPDM, a synthetic rubber known for its excellent resistance to heat, ozone, and automotive fluids. The molded design of the Gates 51798 hose provides a precise fit with end diameters of 1.7 inches (43 mm) and 1.75 inches (44 mm), accommodating the specific radiator connections on Ram 2500 and 3500 trucks. With a centerline length of 24.13 inches (613 mm), this hose maintains proper coolant flow and system pressure without kinking or collapsing. The absence of an internal spring allows for natural flexibility while maintaining structural integrity.

Common Applications and Problem Solving

• Replacement of worn or cracked radiator coolant hoses on Ram 2500 and 3500
