Radiator Flush + Cleaner 1-Gal, Cooling System Cleaner - Prestone AS105R (6-PACK) The Prestone AS105R Radiator Flush Cleaner is a powerful, professional-grade solution designed to remove rust, scale, and debris from vehicle cooling systems. This concentrated formula restores optimal coolant flow by cleaning internal passages in the radiator, heater core, water pump, and engine block?helping prevent overheating and prolonging the life of your vehicle?s cooling system. Formulated for use in all gas and diesel engines, including those with aluminum components, the AS105R safely dissolves built-up contaminants without damaging seals, hoses, or metal parts. It is ideal for use before coolant changes, seasonal maintenance, or when signs of reduced cooling efficiency appear?such as fluctuating temperatures or reduced heater output. To use, simply pour the concentrate into the radiator or overflow reservoir, add water, and run the engine at idle for 15 to 30 minutes. After flushing, drain the system completely and refill with fresh antifreeze/coolant. This process helps ensure maximum heat transfer and prevents clogs that can lead to costly repairs. The AS105R is compatible with all types of antifreeze, including ethylene glycol and propylene glycol-based coolants, and works in both domestic and imported vehicles. Its ready-to-mix concentrate provides multiple treatments per container, offering excellent value for mechanics and DIYers alike. Packaged in a durable 1-gallon container weighing 2.35 lbs (1.07 kg), it?s easy to store and handle. The compact dimensions (11.1" x 7.6" x 9.7") make it suitable for garage shelves or toolboxes.
