Prestone Cooling System Flush is a specialist cleaning product designed to remove dirt, contaminants, and deposits from your car’s cooling system. This deep clean eliminates dirt and limescale, reducing corrosion and improving the lifespan of internal components.

If you’ve done a cooling system flush before, you might have used water to remove old coolant/antifreeze. But water doesn’t clear away deposits and scale; in fact, it can contribute to the problem.

Seeking a solution, the experts at Prestone developed Cooling System Flush – a powerful cleaner that removes dirt, deposits, and contaminants from the cooling system when flushing the radiator. Safe for all engines and all cooling system components, Cooling System Flush is an effective way to maintain the materials within the cooling system, including metals, plastics, gaskets, and hoses.
