About the Molded Coolant Hose Product Line

The Molded Coolant Hose line by Gates focuses on precision-engineered hoses that are molded to exact specifications for specific vehicle applications. This approach ensures a secure fit and optimal coolant flow, reducing the risk of leaks and premature wear. The 23604 part number is part of this line, providing a reliable replacement hose for Dodge Ram trucks that require a molded radiator coolant hose.

Detailed Product Description

The Gates Molded Coolant Hose 23604 is manufactured from EPDM, a synthetic rubber known for its excellent resistance to heat, ozone, and automotive fluids. The molded construction allows the hose to maintain its shape and fit precisely between radiator connections, with an 18.3-inch centerline length accommodating the specific routing in Dodge Ram 1500, 1500 Classic, 2500, and 3500 models. The hose features two different inside diameters—1.75 inches (44 mm) on one end and 2 inches (51 mm) on the other—to match the radiator and engine fittings accurately. This hose does not include springs or quick connect fittings, simplifying installation and maintenance.
