Radiator Elbow 90° Freightliner

The Automann 561.4619 90° radiator elbow is a precision cooling component used primarily in Freightliner engines and chassis. Both ends feature a 2.500″ inner diameter to match radiator and hose interfaces. Its construction is EPDM/silicone rubber reinforced for durability, offering corrosion resistance and maintaining flexibility under engine vibration and thermal expansion. The elbow has equal-length legs (centerline lengths) to route coolant around tight corners with minimal flow disruption: about 4.000″ in both long and short side directions. The part cross-references OEM Freightliner numbers 05-16062-090 / 0516062090. It is listed as part 561.46190 in many catalogs. The design helps maintain coolant flow integrity and seal under high-pressure cooling systems and frequent thermal cycling in heavy truck service.
