The Prestone AS105Y Total Cooling System Cleaner is a premium 2-in-1 formula designed for either a quick flush or a heavy-duty cleaning of your vehicle's cooling system. This 22 oz liquid cleaner effectively removes rust, corrosion, scale, and solid materials, which helps prevent overheating, a leading cause of engine failure. Its formula is safe for use on all metals and radiators and is compatible with all manufacturers' cooling systems. Specifically intended for vehicles with heavier build-ups of rust and deposits in the radiator and heater core, this cleaner works to increase overall system life and performance. The sweet-scented liquid is composed of Sodium Citrate and Water and is packaged in a convenient 22 oz bottle. Its pH range is 7.5 to 9.5, with a viscosity of 1 cSt and a flash point of 215 deg F.
