Prestone says its newest coolant is five times more effective at protecting against corrosion

Prestone Products Corporation, a leader in under-the-hood chemicals, announced that Prestone antifreeze/coolant with patented Cor-Guard corrosion inhibitors is five times more effective at protecting against corrosion than the leading branded competitor. Guaranteed for all vehicles, Prestone antifreeze/coolant delivers longer engine life, according to the company. Engineered with Cor-Guard, this Prestone product fights corrosion and keeps 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 robs engines of performance and causes premature failure. Prestone offers a unique solution to this issue through this patented corrosion inhibitor package, preventing corrosion from forming on water pumps and radiators better than the next leading branded competitor, according to the company.

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

Prestone‘s Cor-Guard formula is available in two products. Prestone Concentrate Antifreeze/Coolant should only 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 protection of Prestone’s Cor-Guard formula. It can be added to any existing fluid to optimize the cooling system.
