Prestone HOAT or hybrid-OAT antifreeze is a low silicate-based automobile coolant infused with neutralized organic acids that protect engine parts from corrosion. This extended-life coolant with its patented formula works with light-duty trucks as well as with all car models and makes.
The Prestone HOAT antifreeze provides as high degree of balance and increased protection against extreme temperatures, while its silicates provide rust corrosion in cooling system materials such as aluminum surfaces. It thereby enhances engine component durability while preserving performance. This coolant meets the requirements and specifications prescribed by auto manufacturers and may be used in all vehicle types.
