This is a molded radiator coolant hose designed for certain Freightliner Cascadia models. It carries engine coolant between the radiator and the engine, manufactured from EPDM rubber with a single-ply polyester reinforcement for durability under high temperatures and pressure. Replacement is typically needed when the hose becomes soft, swollen, cracked, or starts leaking, which can lead to coolant loss and engine overheating. This hose is a direct aftermarket replacement for the OEM hose.
OEM number 0521969000. Designed for radiator coolant routing. Verify engine family and production year; the hose fits specific cooling system configurations. The 'Air System' category on the inventory appears incorrect—this is a coolant hose.
