Keep coolant moving through the heater circuit with the Gates HVAC Heater Hose / Radiator Coolant Hose (MPN 19830), a direct-fit replacement for the 2017-2019 Chevrolet Bolt EV and 2004-2007 Saturn Vue. This is the LOWER, engine-to-heater hose, carrying coolant between the engine and the heater core.

  • Position: Lower, engine-to-heater routing.
  • Function: Carries coolant between the engine and the heater core as part of the cooling/HVAC loop.
  • Dual listing: Cataloged under both names — HVAC Heater Hose and Radiator Coolant Hose.
  • Direct-fit: Application-specific replacement for the listed vehicles.

Over time a coolant hose can crack, swell, soften, or seep at its connections, letting coolant escape. If a worn lower engine-to-heater hose is the cause of a leak or coolant loss, this replaces it — diagnose the cause before replacing. Inspect the clamps and connections during installation and refill and bleed the cooling system per the vehicle service procedure.
