ECR Radiator Hose Freightliner

The Automann 561.46511 ECR radiator hose is a specialized coolant hose for Freightliner trucks, engineered to maintain proper flow and routing under engine heat and vibration. It incorporates a 25° special bend elbow, making it suitable for tight coolant path geometries. Its inner diameter is 2.500 inches, matched on both inlet and outlet ends. Construction utilizes 1-ply polyester reinforcement over EPDM rubber to resist pressure and flex fatigue. The part cross-references Freightliner 05-22451-001 and 0522451001, making it a direct replacement in applications that require this specific elbow hose. Available vendors list the hose weight at 0.30 lbs and packaging dimensions ~4.815 × 3.625 × 2.85 in. This hose helps maintain optimal coolant circulation and contributes to leak-free performance in demanding diesel engine environments.
