Keep coolant moving between the radiator and engine with the Dayco Radiator Coolant Hose 70817.

  • Coolant routing: carries engine coolant between the radiator and the engine/water pump to help maintain proper cooling-system circulation.
  • Cataloged position: listed in upper and lower positions, including pipe-to-radiator, pipe-to-engine, and water-pump-to-chain-case routings; the position that applies depends on your specific vehicle.
  • Signs it may need replacing: cracks, bulges, soft or swollen spots, and coolant seepage at the hose or its connections.

If a deteriorated coolant hose is the cause of a leak or coolant loss, replacing it with this Dayco hose restores that section of the cooling circuit. Inspect the clamps and connecting fittings during installation and diagnose the underlying cause before replacing. Manufacturer part number 70817.
