Super Coolant Radiator Additive 12x16oz

Lucas Oil Super Coolant Radiator Additive 12x16oz is a professional-grade cooling system treatment engineered to enhance the performance and longevity of vehicle radiators and engine coolant. Designed for fleet operators, automotive technicians, and serious vehicle owners, this additive addresses the real-world challenge of coolant degradation, corrosion, and heat dissipation inefficiency that develops over thousands of miles. The bulk 12-pack format makes it an economical choice for workshops, service facilities, and multi-vehicle operations that demand consistent cooling system maintenance.

Each 16-ounce bottle of Super Coolant formulation works by creating a protective film on internal cooling passages, reducing scale buildup, and preventing corrosive oxidation that degrades standard coolant over time. The additive's chemistry enhances heat transfer efficiency, allowing engines to maintain optimal operating temperatures even under heavy load or high ambient conditions. Lucas Oil's proprietary blend is compatible with both conventional and extended-life antifreeze coolants, making it versatile across domestic and import applications. The pint-sized bottles are easy to measure and dispense, and the 12-bottle set ensures adequate supply for routine maintenance across multiple vehicles without frequent reordering.

This product benefits owners of light-duty trucks, SUVs, sedans, and specialty vehicles experiencing coolant issues such as overheating, white residue buildup, or rust-colored discoloration in the reservoir. It is particularly valuable for vehicles operating in extreme climates, towing service, or high-performance applications where stock coolant may reach saturation limits. Simply add one bottle per cooling system flush cycle or mix into existing coolant according to the manufacturer's recommendations—no special tools or expertise required. The 15.15-pound case dimensions make it suitable for storage in service bays, garages, or vehicle maintenance kits for immediate access when needed.
