Antifreeze Industry-Leader Provides Cutting-Edge Technology to Improve Engine Life

Chicago, IL. – The groundbreaking Cor-Guard® corrosion inhibitors, developed by Prestone Products Corporation, are five times more effective at protecting against corrosion than the next leading branded antifreeze/coolant. Guaranteed for all vehicles, Prestone antifreeze/coolant delivers longer engine life. Engineered with Cor-Guard®, this Prestone product sets the industry standard in fighting against corrosion and keeping cooling systems running more efficiently.

Prestone‘s Cor-Guard formula reduces the risk of breakdowns, and keeps engines free from the damaging effects of worn-out antifreeze. Corrosion is the enemy of any cooling system, robbing engines of performance and causing premature failure. Prestone offers a unique solution to this issue through this patented corrosion inhibitor package. Prestone begins to work immediately and is five times more effective than the next branded competitor at preventing corrosion from forming on water pumps and radiators.

Prestone‘s Cor-Guard formula is a result of seven years of research and development at the renowned Prestone® Innovation Center. The formula improves existing technology while maintaining the product’s versatility to work in any car and light-duty truck.

Prestone‘s Cor-Guard formula is available in two products. Prestone® Concentrate Antifreeze/Coolant can be used to fill radiators after a thorough flush and clean. Alternatively, Prestone® 50/50 Prediluted Antifreeze/Coolant is a quick and convenient way to top off a car’s cooling system with the superior protection of Prestone’s Cor-Guard formula. It can be added to any existing fluid to improve protection for the cooling system.
