Not For Use In Cooling Systems That Use Proprietary or Manufacturer Specific Coolants. Lucas Super Coolant has been scientifically formulated to provide the ultimate protection in automotive and racing cooling systems. It protects the entire system from rust, corrosion and electrolysis including aluminum and has been proven to reduce coolant temperatures up to 20°F. Our unique formula prevents deposits that can cause overheating. Lower cylinder head temperatures means advanced ignition time and more horsepower.
