Product Details

Gates Molded Coolant Hose part number 51417 is part of the brand’s modular coolant hose line, which is built around vehicle-specific fitment and OE-style integrated components. This hose is shaped for the upper radiator coolant path on the Mercedes-Benz C250 and uses molded construction to match the original hose routing more closely than universal hose options. The design includes quick-connect interfaces and modular components that align with the original cooling system layout.

This part cross-references Dayco 73100 for the same application. If you are replacing a worn Mercedes-Benz C250 upper coolant hose, Gates 51417 provides a direct replacement path for the 2012-2015 model years.

Common Problems This Hose Can Address

• Coolant leaks from a cracked or aged upper radiator hose
• Softening, swelling, or heat damage in the original hose material
• Loose or damaged quick-connect fittings at the cooling connection points
• Improper hose routing caused by a non-molded replacement
• Cooling-system service needs on a 2012-2015 Mercedes-Benz C250

Installation Notes and Tips

Verify the hose routing, connector style, and end diameters before installation. Inspect the mating necks, seals, and adjacent cooling components for wear or residue before connecting the new hose. Because this is a molded, application-specific hose, correct orientation matters for proper fit on the Mercedes-Benz C250 upper cooling circuit.
