Ultra-Tech 50/50 Antifreeze


Our Full-Strength, Heavy-Duty, Antifreeze is a non-silicate, non-phosphate formulation that contains the initial charge of supplemental coolant additive (SCA) and a minimum of 2400ppm Nitrite (as NO2). It provides outstanding protection from cavitation erosion/corrosion in water pumps and wet sleeve cylinder liners, as well as excellent overall corrosion protection. In addition, this Heavy-Duty, Full Strength Antifreeze contains an advanced additive inhibitor system to provide broader range protection than most coolants. This includes ingredients to disperse minor oil leakage, prevent fouling and control hot surface scaling. The antifreeze meets ASTM D 3306 (Automotive Prediluted Antifreze), ASTM D 4985 (Heavy-Duty Prediluted Antifreeze) and ASTM D 6210 (Heavy-Duty Precharged, Fully-Formulated Antifreeze). It also meets or exceeds the following industry specifications as a concentrate or pre-diluted antifreeze/coolant:


  • ASTM D 3306, D 4985, and D 4340
  • Cummins 90T8-4, 3666132
  • GM 6043M, 1899M and 1825M
  • Ford ESE M97B44A & ESE M978B18-C
