UltraCool Universal Antifreeze + Coolant CONCENTRATE (Blue) is a premium, ethylene glycol antifreeze + coolant for heavy-duty diesel, gasoline, and natural gas-powered engines that protects your complete cooling system all year-round. Recommended for use in all makes and models of European, Asian, and American cars and trucks. It can be used in both aluminum and conventional metal engine cooling systems of heavy-duty diesel engines, automobiles, trucks, marine and industrial stationary equipment. Formulated with deionized water, a low silicate rust and a corrosion inhibiter system that effectively alleviates gel formation problems and prevents radiator heat transfer capacity loss.

Ready to mix (Note this is a concentrate to be mixed with distilled water based on the mix chart on the packaging) At BluePrint engines, we felt it's better to offer a gallon of concentrate (opposed to pre-mix), so your dollar goes further, and we're not charging you for water!!!
