Gates 51976 Molded Coolant Hose Overview

The Gates 51976 molded coolant hose is a direct-fit radiator coolant hose for specific Hyundai and Kia applications. Built with EPDM and plastic, it follows OEM-style routing and integrates the application-specific features needed for a precise upper hose replacement.

Compatible with 2017-2022 Hyundai Ioniq and 2017-2021 Kia Niro upper coolant hose applications, this molded hose is shaped for the correct centerline length and end dimensions. Gates 51976 is engineered for vehicles that use a female quick connector and other integrated OE-style components.

Product Details

Gates 51976 is part of the Molded Coolant Hose line, which focuses on application-specific radiator and coolant hose replacement. Gates builds this hose to match the original routing and essential integrated features used on the vehicle, including the female quick connector called out for the application. This makes it a practical replacement for upper coolant hose service on Hyundai Ioniq and Kia Niro models where the factory hose uses molded geometry rather than a universal straight hose.

This part cross-references Monroe Shocks & Struts (e.g., 25414G2300, F11359) for the same application. The Gates 51976 part number is also useful when searching for an OE-style molded coolant hose for the Hyundai Ioniq or Kia Niro upper hose position.

Common Problems This Hose Can Address

  • Cracked or brittle upper radiator hose material
  • Coolant seepage at molded hose sections or connector points
  • Incorrect fit from a universal hose replacement
  • Loss of proper hose routing in the engine bay
  • Service replacement for a worn female quick connector hose assembly

Installation Notes and Tips

Verify the vehicle year, make, model, and upper hose position before installation. Confirm the end diameters and connector style match the original hose routing on the vehicle. Inspect adjoining coolant system components, clamps, and connection points for wear or residue before installing the new hose. Proper coolant refill and bleed procedures should be followed after replacement.

Quality Assurance

Gates is a recognized automotive aftermarket supplier with a focus on modular coolant hose assemblies that mirror OE-style application requirements. The 51976 molded coolant hose is built for specific vehicle fitment and cooling system service.
