Anotation

This specification covers the requirements for fully-formulated glycol base coolants for cooling systems of heavy-duty engines. When concentrates are used at 40 to 60 % glycol concentration by volume in water of suitable quality, or when prediluted glycol base engine coolants (50 volume % minimum) are used without further dilution, they will function effectively during both winter and summer to provide protection against corrosion, cavitation, freezing, and boiling. The coolant concentrate mixed with water or the prediluted coolant, when maintained with maintenance doses of supplemental coolant additives (SCA), shall be suitable for use in a properly maintained cooling system in normal service for a minimum of two years. In addition, the coolant concentrate or prediluted coolant shall provide protection in operating engines against cavitation corrosion (also termed liner pitting) and against scaling of internal engine hot surfaces. Hot surfaces typically are within the engine head, head spacer, upper cylinder liner, or liquid cooled exhaust manifold.
