The D 68800 Water Hose – Bottom (HSA) is a heavy-duty lower radiator water hose designed for CASE 580 C and CASE 580 D backhoe loaders. This hose connects the lower radiator outlet to the engine cooling circuit, allowing cooled coolant to return efficiently to the engine and maintain stable operating temperature.
Manufactured by HSA, this hose is produced using reinforced, high-quality rubber that resists heat, pressure, vibration, and coolant corrosion commonly encountered in construction and earthmoving applications. Its durable construction helps prevent leaks, swelling, and premature failure, ensuring reliable long-term performance.
Designed to OEM-correct dimensions, this bottom radiator hose allows direct replacement without modification, making it ideal for routine maintenance, cooling-system repair, or full engine overhaul.
