This hose carries engine coolant through the heater circuit, and is cataloged for the heater inlet and heater outlet positions.

Over time, coolant hoses can harden, crack, swell, or chafe at their connections. If a failed or leaking heater hose is the cause of coolant seepage, damp spots under the dash or in the engine bay, a dropping coolant level, or weak cabin heat, replacing it with this hose restores the intended coolant path. Always diagnose the cause before replacing, and follow the vehicle service information for correct routing and clamp installation.
