A radiator hose carries hot coolant through the cooling circuit so the engine can shed heat. Over time, heat and pressure cycling can leave a hose cracked, bulged, soft, or leaking. If a worn or failed hose is the source of a coolant leak or loss, this hose replaces it; diagnose the cause before replacing so any related components are addressed.
