The molded EPDM design helps maintain proper hose routing and connection points, while the heat- and ozone-resistant construction is suited for demanding underhood conditions. This hose is a practical OE-style replacement for Mercedes-Benz CLK430, CLK55 AMG, and C43 AMG models that require the upper radiator hose configuration.

This part cross-references Rein (e.g., CHR0435) for the same application.

Common Repair Symptoms

• Coolant leaks at the upper hose connection
• Cracking, swelling, or softening of the hose rubber
• Overheating caused by restricted coolant flow
• Visible deterioration from heat or ozone exposure
• Loss of sealing at molded bends or end connections

Installation Notes

Inspect hose clamps, necks, and adjacent cooling components before installation. Confirm the routing matches the original upper hose path and verify the hose seats fully on the radiator and engine-side connections. After installation, refill and bleed the cooling system according to the vehicle service procedure and check for leaks at operating temperature.

Quality Assurance

URO part number 2025015982 is backed by a 24-month unlimited mileage warranty. The hose is precision-molded for OE-style fit and made from ECD-resistant EPDM to help resist internal rubber breakdown from electrolysis.
