Keep Cool Water Conditioner | NEO Synthetic Oil

Keep Cool Water Conditioner


NEO KEEP COOL is our original powerful inhibitor with over 30 years of successful history. It is an exclusive Neo Synthetic Oils process of inhibitors concentrated to give maximum resistance to rust, corrosion and mineral deposits in water transfer systems. Sold in 8oz bottles.


Cooling water, like fuel and lubricating oil, is a consumable store, which should be carefully selected, treated and continually monitored. If this is neglected, corrosion, erosion and cavitations may occur on the waterside of the cooling systems and deposits may form which will impair heat transfer and may cause thermal overloading of the parts which must be cooled.

NEO’s Keep Cool unique formula provides better heat transfer and prevents rust, corrosion, and mineral deposits in your engine’s cooling system, especially with aluminum. Recommended by leading racing radiator companies and engine builders as a great additive.

  • Safe for all racing surfaces.  Completely safe and easy to use, non-toxic, and passes all safety tests.  Non-injurious to all metals, paints, clothing, or human skin.
  • The finest water pump lubricant; no gummy residue to clog thermostats; will not gel; cleans while you drive.  Gently extends water hose life.
