Prestone Super Radiator Flush is a premium Prestone antize and coolant change solution designed to enhance your vehicle’s cooling system performance. This advanced formula helps remove rust deposits and oily residue through an easy, one-step process. It maximizes cooling system efficiency by flushing out harmful rust, grease, and other corrosion deposits using a strong chelating compound that binds and eliminates these contaminants before new antize is added. The detergents in the formula emulsify oily residues, making it especially effective for cars with heavier buildups of rust and deposits in the radiator and heater core. Super Radiator Flush ensures a cleaner, more efficient cooling system and helps maintain your vehicle’s optimal temperature regulation. Model Number: AS105Y
