Product Details

Gates 52108 is a radiator coolant hose made from EPDM, a material commonly used in cooling-system service for its resistance to heat and coolant exposure. This molded hose is shaped for the upper connector-to-engine position and is listed for 2019-2025 Ram 2500 and 2019-2025 Ram 3500 models with OE adapter required. For buyers searching for a Ram 2500 upper radiator hose or Ram 3500 molded coolant hose replacement, part number 52108 provides a direct-fit service option within the Gates molded coolant hose family. This part cross-references F11612 for the same application.

Common Problems It Can Address

  • Cracked or leaking upper coolant hose
  • Softened hose material from heat cycling
  • Incorrect hose routing after cooling-system service
  • Coolant seepage at the connector-to-engine connection
  • Restricted coolant flow caused by a deteriorated hose

Installation Notes and Tips

Verify the OE adapter requirement before installation on Ram 2500 and Ram 3500 trucks. Match the molded shape, end diameters, and centerline length to the original hose routing before removal. Inspect adjoining connectors, clamps, and the engine-side connection for wear or residue so the replacement hose seats correctly. Confirm the cooling system is properly filled and bled after service.

Quality Assurance

Gates manufactures molded coolant hoses to OEM-quality specifications and offers broad coverage across replacement cooling-system applications. Part number 52108 is part of the Gates Molded Coolant Hose line, which is engineered for service replacement across multiple coolant hose positions.
