The ACDelco heater hose routes coolant between the engine and the cabin heater core on the Honda Accord. EPDM construction with knit-cord reinforcement resists heat cycling. Heater hoses degrade on the same schedule as radiator hoses — pinhole leaks into the distributor or cabin are documented failures on aging vehicles.

Fits: 2000-2024 Honda Accord (all engine variants).
