Detailed Product Description
The Gates Molded Coolant Hose from the Molded Coolant Hose product line is specifically designed to meet the cooling system demands of heavy-duty Ram trucks. This radiator coolant hose features a molded design with two branches, allowing it to fit complex coolant pathways without the need for additional connectors or modifications. The hose is constructed from EPDM rubber and plastic, materials known for their resistance to heat, ozone, and coolant chemicals, which helps maintain durability and prevent leaks over time.
The hose ends have an inside diameter of 15 mm (0.59 inches), ensuring a secure connection to the radiator and engine fittings. Multiple centerline length measurements (18.5 mm, 46 mm, and 470 mm) provide flexibility in installation and compatibility with specific Ram 2500 and 3500 configurations. This part does not contain any internal springs, which reduces the risk of internal damage and flow restriction.
