Prestone AS105 Total Cooling System Cleaner – 22 oz, 6 Pack

Description

Prestone AS105 Total Cooling System Cleaner is a powerful 2-in-1 formula designed for both light flushing and heavy-duty cleaning of radiators, heater cores, and hoses. Ideal for preventing engine overheating—the leading cause of engine failure—this cleaner removes rust, scale, and other heavy deposits that can block coolant flow and reduce heat transfer. Its super-chelating additive draws metal oxides into solution, helping restore maximum system efficiency. Despite its strength, the formula is non-toxic, non-acidic, and safe for use on all cooling system metals.
