Product Details

This Dayco curved radiator hose is made for upper coolant routing on Mercedes-Benz Sprinter models where the hose must follow a formed path between the engine and radiator. The EPDM material is selected for coolant exposure and temperature cycling, while the dual I.D. configuration supports the different connection diameters used in the application. If you are replacing a worn or leaking upper hose on a Mercedes-Benz Sprinter 2500 or Mercedes-Benz Sprinter 3500, Dayco 72814 provides the correct curved hose shape and size match for the listed vehicles.

Compatible With: Fits 2019-2023 Mercedes-Benz Sprinter 1500, upper; Fits 2010-2023 Mercedes-Benz Sprinter 2500, upper; Fits 2010-2022 Mercedes-Benz Sprinter 3500, upper; Fits 2018-2022 Mercedes-Benz Sprinter 3500XD, upper. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Replacement Reasons

• Coolant seepage from a cracked or aged upper radiator hose
• Softening, swelling, or collapse of the hose under heat and pressure
• Improper hose fit after prior repair or incorrect replacement part selection
• Loss of coolant flow caused by internal hose deterioration
• Need for a formed hose that matches the factory routing on Sprinter cooling systems

Installation Notes and Tips

Verify the hose routing and connection diameters before installation, especially on Mercedes-Benz Sprinter 2500 and Sprinter 3500 applications. Inspect the radiator neck, engine outlet, and clamps for wear or corrosion before installing the new hose. Confirm the hose is seated fully and routed without twist or contact points that could create abrasion during operation.

Quality Assurance

Dayco manufactures this radiator coolant hose to SAE J20R4 Class D-1 and SAE J1684 Type EC standards, supporting consistent material and dimensional requirements for cooling system service.
